That Girl That Makes Videos About Rocks

Welcome to Scottish Geologist’s website - the home of “That Girl That Makes Videos about rocks”. 

I’m Luisa - a Glasgow-trained geologist who ditched the engineering world after nine years to follow my dream of, well… talking about rocks for a living. And it worked! Now I Make funny, Bite-sized geology videos on TikTok, Instagram, YouTube and Facebook (@scottishgeologist) where more than 600K rock fans follow along.

I started making videos about rocks in March 2023 because I felt like something was seriously missing from social media: a proper appreciation for Scotland’s incredible geological landscapes. So I set out to fix that - one silly, educational video at a time.

As my online community grew, I wanted to take what I do on camera and bring it outdoors. That’s why I created Scot Rock Walks - Scottish Geology Tours ranging from short local walks to full-day and multi-day adventures across Scotland.

Come and explore the birthplace of modern geology with me!

Volcanoes, Beaches & Ancient Seas: A Geology Tour of Gullane with @ScottishGeologist

Join @ScottishGeologist for a stunning coastal geology tour around Gullane, East Lothian—where wide sandy beaches, rocky headlands, and classic Scottish geology come together. This area offers an exceptional snapshot of Carboniferous volcanism, sedimentary environments, and Ice Age landscape change, all in an accessible, walkable setting with big views across the Firth of Forth.

What to Expect

🌋 Carboniferous Volcanic Activity 

  • Explore volcanic rocks formed around 340 million years ago, when this part of Scotland lay near the equator.

  • Examine basaltic intrusions and lava flows exposed along the shoreline and at Gullane.

  • Learn how magma forced its way through soft sediments, baking and altering them at the margins - very good examples of chilled margins.

🪨 Sedimentary Rocks from Ancient Seas and Deltas

  • Walk across sandstones, mudstones, and limestones deposited in warm, shallow seas, lagoons, and river deltas.

  • Identify features such as bedding planes, ripple marks, iron nodules, cross bedding, deformation beds and fossil-rich layers that record shifting environments through time.

🦴 Fossils and Past Life

  • Look for marine fossils—including shells and crinoid fragments—in limestone beds and loose blocks.

  • Discover how these fossils help reconstruct a tropical Carboniferous coastline very different from today’s Scotland.

🌍 Structural geology and plate tectonics 

  • Analyse faults and learn about brittle deformation. 

  • Learn about stresses associated with convergent, divergent and transform plate boundaries. 

🌊 Coastal Processes in Action

  • Observe wave-cut platforms, rock pools, and eroded cliffs that give textbook exposures of the geology.

  • Discuss how modern coastal erosion continues to reveal new sections of rock each year.

👣 Hands-On Geology

  • Practice reading the rocks in the field: distinguishing igneous from sedimentary units and tracing contacts.

  • Use everyday features—beaches, cliffs, headlands—to link big geological ideas to real landscapes.

Who Should Attend?

  • Perfect for beginners, families, students, and anyone curious about Scotland’s coastal geology.

  • Ideal if you enjoy learning outdoors with minimal scrambling and maximum scenery.

The geology of Lower Largo, Fife - Sunday 12th April 2026 15:00-17:00
from £25.00

Join @ScottishGeologist for a fascinating guided walk along the coastline of Lower Largo in Fife, where quiet beaches and rolling farmland hide the remains of an ancient volcanic, tropical and semi-arid landscape.

This geology tour explores the story 315-million-year-old Carboniferous Scotland, when the land that is now Fife sat close to the equator and was shaped by erupting volcanoes, tropical rivers, shallow seas and semi-arid environments.

Standing on the shores of Largo Bay, we’ll uncover the geological history written in the rocks beneath our feet and learn how one dramatic hill in the landscape reveals the plumbing of a long-extinct volcano.

What You’ll Discover

🌋 The Volcano of Largo Law

Towering above the landscape is Largo Law, a striking volcanic plug that formed when magma solidified inside the throat of an ancient volcano.

Over millions of years erosion stripped away the surrounding cone, leaving behind the hardened volcanic core that now dominates the skyline.

On the tour you’ll learn:

  • How volcanic necks form

  • Why Largo Law stands higher than the surrounding landscape

  • What this tells us about Scotland’s Carboniferous volcanic activity

🪨 Reading the Rocks of the Beach

Along the shoreline we’ll examine the rocks that tell the story of a very different Scotland.

Participants will discover:

  • Basalt lava flows formed from ancient eruptions

  • Volcanic ash and tuff deposits from explosive activity

  • Sedimentary rocks laid down in rivers, coastal lagoons, inter-tidal areas and semi-arid environments

Each rock reveals clues about the environment that existed here hundreds of millions of years ago.

🌍 Scotland Near the Equator

During the Carboniferous Period, Scotland was located close to the equator and experienced a warm tropical climate.

This meant:

  • Lush swamp forests covered the landscape

  • Rivers and deltas flowed across the Midland Valley

  • Volcanoes erupted across the region

The rocks around Lower Largo preserve evidence of this remarkable time in Scotland’s deep geological past.

Tour Highlights

✔ Explore a spectacular volcanic and sedimentary landscape

✔ Learn how geologists read rocks like a storybook

✔ See the remains of an ancient volcano up close

✔ Discover the tropical Scotland of 320 million years ago

✔ Experience the coastline of historic Fife through the lens of geology

The geology of the Isle of Lewis and Harris - Friday 24th July to Monday 27th July 2026
from £300.00

Ancient Stones and Atlantic Shores: A Geology Tour of Lewis & Harris with @ScottishGeologist

Join @ScottishGeologist on a breathtaking geological journey across the Isle of Lewis and Harris, where the landscape tells a story stretching back nearly 3 billion years. From the Lewisian gneiss, some of the oldest rocks in Europe, to stunning Atlantic beaches and towering Harris mountains, this tour reveals how Scotland’s Outer Hebrides became a geological wonderland.

What to Expect

🪨 The Lewisian Gneiss Complex

  • Walk across outcrops of Lewisian gneiss, formed over 3.2 billion years ago deep in Earth’s crust.

  • Learn how these rocks were altered by intense heat and pressure, creating their distinctive banded appearance.

  • Understand how these gneisses are fragments of Earth’s earliest continental crust, older than almost all life.

⛰️ The Mountains and minerals of Harris

  • Explore the dramatic Harris hills, where gneiss forms a rugged, rocky landscape shaped by glaciers.

  • See how later intrusions of granite and pegmatite veins cut through the gneiss, telling a story of deep magmatic activity.

  • Trace how these ancient foundations influence the island’s modern topography.

  • Analyse crystals such as tourmaline, mica and quartz in pegmatic form. 

🏜️ The Uig and Stornoway Sandstones

  • Visit exposures of Torridonian-like sandstones, deposited around 1 billion years ago by ancient rivers and deserts.

  • Spot sedimentary structures like ripples and cross-bedding, frozen evidence of vanished landscapes.

⛰️ Structural Geology in the Gneiss

  • Analyse how the Lewisian was deformed over billions of years, recording cycles of burial, heating, and uplift.

  • Look at isoclinal folds, refolded folds, and shear fabrics, and discuss what they reveal about the pressures and directions of ancient tectonic forces.

  • Learn how geologists unravel deformation histories by tracing cross-cutting relationships between different fold generations.

  • Compare the structures in Lewisian gneiss to those found in modern mountain belts like the Himalayas.

🌍 The Outer Hebrides Fault Zone (OHFZ)

  • Explore one of Scotland’s most significant tectonic structures, stretching for more than 200 km along the Outer Hebrides.

  • Understand how this ancient fault marks the boundary between the Lewisian gneiss block and rocks further east.

  • Learn that the OHFZ was reactivated several times:

    • During the Proterozoic, when the Lewisian basement was fractured and sheared.

    • During the Caledonian Orogeny (~430 million years ago), when thrusts and folds developed as Scotland collided with North America and Greenland.

    • Even later, during the opening of the Atlantic, when dykes intruded along fault lines.

  • See spectacular mylonites and sheared rocks, where the gneiss has been ground and stretched by movement along the fault.

  • Discuss how this deep crustal fault connects Arran, the mainland, and the Outer Hebrides, showing how Scotland’s geology is linked across regions.

🌊 Glacial and Coastal Landscapes

  • Discover how the last Ice Age carved corries, valleys, and lochs across Lewis and Harris.

  • Walk along the Atlantic coast, where white-sand beaches like Luskentyre meet outcrops of ancient gneiss.

  • Observe how waves and weather continue to shape the coast today, creating sea stacks, cliffs, and machair grasslands.

🏛️ Geology and Culture

  • Learn how Lewisian gneiss was used in building crofts and stone walls across the islands.

The geology of the Isle of Arran - Friday 12th June to Sunday 14th June 2026
from £300.00

Scotland in Miniature: A Geology Tour of the Isle of Arran with @ScottishGeologist

Join @ScottishGeologist for an inspiring geological tour of the Isle of Arran, often called “Scotland in Miniature” because it showcases almost every type of rock and geological process found across the country. From ancient ocean crust found In north Glen Sannox along the Highland Boundary fault line to folded meta-sediments that were deformed during the Caldeonian orogeny (mountain building) to the granite mountains, fossil-rich sandstones, and famous unconformities, Arran is one of the best places in the world to explore Earth’s story in a single island.

What to Expect

🌍 Deep Time on Display

  • Walk through hundreds of millions of years of Earth history in a single island, from Precambrian metamorphic rocks to Tertiary granites and dykes.

  • Understand why Arran is nicknamed “Scotland in Miniature”—its rocks represent almost every major stage of Scotland’s geological story.

🪨 Hutton’s Unconformity at Lochranza

  • Stand at the site where James Hutton, the father of modern geology, found one of his most famous examples of unconformity.

  • See how vertical Dalradian schists (c. 500–600 million years old) are overlain by much younger Devonian sandstones (~370 million years old).

  • Learn how this relationship gave Hutton evidence for “deep time” and the endless cycles of rock formation.

🌋 Igneous Geology: The Arran Granite and Beyond

• Explore the granite mountains of North Arran, intruded around 60 million years ago during the opening of the North Atlantic.

• Learn how slow-cooling magma deep underground produced the rugged Goatfell massif.

• Trace dyke swarms that cut through older rocks, part of the same magmatic activity that shaped Skye and Mull.

• See where igneous intrusions altered surrounding rocks by metamorphism (contact aureoles).

🧭 Structural Geology and Tectonics

  • Identify folds and faults in Dalradian metamorphic rocks.

  • Learn how these structures formed during the Caledonian Orogeny (~430 million years ago), when Scotland was part of a giant mountain belt like today’s Himalayas.

  • Discuss how later extension and volcanism reshaped the island

👣 Hands-On Exploration

  • Use simple field skills: sketching outcrops, noting sedimentary structures, and identifying igneous textures.

  • Compare rocks of very different ages side by side.

  • See how Arran acts as a “natural classroom,” ideal for connecting big geological ideas with real-world rocks.

🏜️🏝️Sedimentary Stories

  • Walk across Devonian Old Red Sandstone, laid down in rivers and desert basins when Scotland lay near the equator.

  • Visit Carboniferous rocks with limestones, sandstones, and shales, packed with fossils of corals, crinoids, and plants, evidence of warm shallow seas and swampy deltas.

  • Examine the Permian sandstones of southern Arran, deposited in arid desert conditions, their vivid red colour still striking today. 

Who Should Attend?

  • Geology enthusiasts and students eager to see world-famous outcrops.

  • Walkers, families, and nature lovers looking to understand Arran’s landscapes more deeply.

  • Anyone curious about James Hutton and the birth of modern geology.

No prior geological knowledge needed—just sturdy footwear and a sense of curiosity!

The geology of Ardnamurchan - Friday 26th June to Sunday 28th June 2026
from £300.00

Inside Scotland’s Ancient Volcano: A Geology Tour to Ardnamurchan with @ScottishGeologist

Join @ScottishGeologist for a spectacular field excursion to the Ardnamurchan Peninsula — the best-preserved Palaeogene (Tertiary) volcanic complex in the UK, and one of the finest exposed volcanic ring structures in the world. This is a rare chance to step inside the heart of an ancient volcano, where lava once erupted, magma forced its way into the crust, and geological structures were frozen in time.

What to Expect

🌋 Explore a Classic Eroded Volcano

  • Stand inside the remains of a 60-million-year-old central volcanic complex, formed during the opening of the North Atlantic.

  • Learn how Ardnamurchan’s gabbroic ring structures, cone sheets, and radial dykes were formed as magma rose through the Earth’s crust.

  • Understand the anatomy of a volcano from the inside out: magma chambers, feeder systems, and surface eruptions — all visible in 3D.

🧭 The Famous Ring-Dyke Complex

  • Walk across the textbook example of a ring dyke, formed when the central magma chamber collapsed and magma injected into concentric fractures.

  • Observe radial dykes that radiate from the old volcanic centre like spokes on a wheel.

  • Understand how geologists interpret volcanic plumbing systems using these kinds of structures.

🪨 Gabbro, Basalt, and Beyond

  • Examine coarse-grained gabbro, crystallised slowly within the magma chamber, alongside finer-grained basaltic intrusions.

  • Learn how differences in cooling rate and magma chemistry affect mineral textures and rock types.

  • Identify minerals like plagioclase, pyroxene, and olivine, common in mafic volcanic systems.

📏 Geological Structures in the Field

  • Measure and sketch dykes, sills, and cone sheets, and interpret how they relate to the broader volcanic structure.

  • Try basic field mapping and orientation exercises, guided by clear outcrop patterns in the landscape.

  • Discuss the link between Ardnamurchan and modern volcanoes like those in Iceland.

🌊 Wild Coastlines and Erosion

  • Explore how coastal erosion has cut into the volcano, exposing deep levels of its plumbing system.

  • Visit dramatic sea cliffs, headlands, and raised beaches, where geological processes from different eras intersect.

📚 From Volcano to Field Lab

  • Learn how Ardnamurchan became a classic site in British geology, featured in textbooks and taught at universities worldwide.

  • Discuss the site’s scientific importance in understanding volcanic ring complexes and collapse structures.

Who Should Attend?
