Drape folds are different to those that have formed by compression. They form traps in oil fields and a nice example is shown here from Somerset, UK.

A wee write up of our Aberdeen Geological Society trip to Skatie Shore on 30th August 2026

A wee bit of advertising for this geology trip to the highly deformed Dalradian age rocks just North of Stonehaven. With Aberdeen Geological Society.

Beautiful set of thrust faults in the Hopeman Sandstone that may have formed shortly after sand deposition (Permian period).

Molybdenum and small amounts of gold can be found in quartz veins in the Souter Head Complex, just S of Aberdeen, UK.

This spectacular unconformity at Arbroath is one of several Scottish locations that appear in the observers book of geology

Gloom Hill Quarry, outside of the town of Dollar in Clackmannanshire, now abandonned, supplied quart dolerite for various uses such as road surfacing. There are many types of joints here.

One hour long montage of field trip to the Moray Coast (Hopeman Sandstone), UK, to celebrate the life and work of Professor Ken Glennie in early May 2026. That’s me above btw, not Ken !

On 8th June 2026, I co-led a geology trip to the Stonehaven coast as part of the EAGE annual conference in Aberdeen. Wide range of geological features here in what is quite a controversial area of Scottish geology

This boulder of gneiss sits on the beach of Craigeven Bay, just South of Aberdeen, Scotland - but it’s not from here - read on to find out more…

Great view of the Clashach Fault from hilltop on other side of the bay - read on to find about a bit more about this well exposed fault on the Moray coast.

Not all folds in rocks form deep in the Earth’s crust - some examples here from the Scottish Fife coast have formed soon after sandstone deposition

The disused quarry at Lethen House, just South of Auldearn (in Moray, Scotland) has exposed sediments where fossil fish bearing nodules can be found together with plant remains.

We are surrounded by granite in Aberdeen, mainly the Rubislaw granite but there’s quite a variety at Aberdeen Art Gallery

A pleasant circular (& short) walk taking in a little bit of geology in the River Tummel

During the Devonian period (around 410 million years ago) there was a big lake in the Forfar area - we know this due to fossil fish found there

Not a classic location for Scotland’s Geology - but I decided to take a look - glad that I did !

This example of mechanical stratigraphy where thinner limestone beds are more fractured than thicker ones, is from Iran. Plenty of examples from Scottish geology here as well..

The Lower Devonian conglomerates have supplied pebbles for a spectacular beach at Auchmithie. It is also host to a range of structural (geological) features.

I wonder what future generations of geologists would make of the polystyrene clasts in this rock
