In amongst the pebbles in my last post, there is a crop of what i understand to be Canisp Porphyry. They were uncovered quite dramatically after one of last year's storms. Since then, they have obviously moved around and are no longer so concentrated in one spot as they had been. Who knows how it all got there or how long it has taken to round their edges into perfect pebbles.

Rock appreciation - amygdaloidal andesite from the Angus coast, telling a story of violent volcanic eruptions that took place over 400 million years ago 🌋🏴󠁧󠁢󠁳󠁣󠁴󠁿 #ScottishGeology

Here’s some wee 330 million year old crinoid ossicles that wonderfully illustrate their five-fold radial symmetry. Nature is awesome 🖤 #ScottishFossils #ScottishGeology

The next open day at Fossil Grove in Victoria Park, Glasgow, is tomorrow (Sunday the 16th July) from 12-4pm! Head along to see this awesome 330 million year old fossilised forest and learn about life in equatorial Scotland during the carboniferous period 🏴󠁧󠁢󠁳󠁣󠁴󠁿🖤 #ScottishFossils #ScottishGeology

A goth in her happy place 🖤 Awesome to back at Fossil Grove - a truly spectacular example of an in-situ 330 million year old fossilised forest, right in the heart of Glasgow 🏴󠁧󠁢󠁳󠁣󠁴󠁿 #ScottishFossils #ScottishGeology

Awesome liesegang banding and iron staining in the carboniferous sandstones at Pathhead Sands, Kirkcaldy 🖤 #ScottishGeology

A wild agate appeared! #ScottishGeology

Geological pilgrimage to Hutton’s Unconformity on Arran 🖤 the basement precambrian dalradian schists are unconformably overlain by early carboniferous sediments - a gap in the rock record of almost 200 million years! #ScottishGeology

Honeycomb weathering in the permian new red sandstones at Corrie 😍 #ScottishGeology
