just Naomi 🏳️‍⚧️<p>You've got to love Roach Stone - it's a facies (variety) of the famous Portland Stone (a Jurassic limestone) that many of the public buildings in London are built from. Christopher Wren made Portland Stone famous when he used it to build the new St Paul's Cathedral in London after the Great Fire. OK, so he had shares in the quarry...</p><p>The stone is full of fossil shells - the pointy ones are the famous 'Portland Screws'.</p><p><a href="https://tech.lgbt/tags/Geology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Geology</span></a> <a href="https://tech.lgbt/tags/UrbanGeology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>UrbanGeology</span></a> <a href="https://tech.lgbt/tags/Limestone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Limestone</span></a> <a href="https://tech.lgbt/tags/PortlandStone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PortlandStone</span></a> <a href="https://tech.lgbt/tags/RoachStone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RoachStone</span></a> <a href="https://tech.lgbt/tags/Jurassic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Jurassic</span></a> <a href="https://tech.lgbt/tags/ChristopherWren" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ChristopherWren</span></a> <a href="https://tech.lgbt/tags/FossilFriday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FossilFriday</span></a></p>
This Is My Glasgow<p>Differential erosion on a red sandstone mask on the Trustees Savings Bank in Springburn.</p><p>The lines across this scultpture are created by layers of different composition and hardness within the 270 million year old sandstone, which means they weather at different rates.

haq<p>Urban fossil hunting fun from a 19th century wall built 1822-66 in Ledbury, Herefordshire. These brachiopod shells and crinoid stems, and colonial coral, are preserved remains of animals that lived in a warm shallow sea about 430 million years ago. I don't know which quarry these ashlar blocks originated from but they're Much Wenlock Limestone. They can be found on the Barrett Browning Institute facing The Homend, named for poet Elizabeth Barrett Browning, which is appropriate as I was there for the literary festival. There are also crinoid stems in the cobbles paving Church Lane.</p><p><a href="https://kolektiva.social/tags/FossilFriday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FossilFriday</span></a> <a href="https://kolektiva.social/tags/fossils" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>fossils</span></a> <a href="https://kolektiva.social/tags/UrbanGeology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>UrbanGeology</span></a> <a href="https://kolektiva.social/tags/urbanism" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>urbanism</span></a> <a href="https://kolektiva.social/tags/Herefordshire" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Herefordshire</span></a> <a href="https://kolektiva.social/tags/WenlockWednesday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>WenlockWednesday</span></a></p>

ricardo vacapinta<p>The center of Amsterdam is full of fossils if you look down. Much of the pavement border is Kilkenny Limestone which was rich in Carboniferous fossils.

AnthropoceneMan<p>Petrology Assistance Needed</p><p>What am I looking at here? It has been 40 years since Ig/Pet and I am rusty as hell.</p><p>Looks like settling of “clots” of early crystallizing kspar/hornblende that settled into the bottom of the magma chamber where they were both rounded and “attacked” by the magma at the bottom due to incompatibility.

just Naomi 🏳️‍⚧️<p>It's not often that you see rock trying to pass itself off as Kendal Mint Cake, but these blocks of Carrara Marble cladding Birmingham Bullring's Rotunda are doing a pretty good impression of it. </p><p>We're probably(!) more used to seeing Carrara Marbles slabbed or sculpted and then polished, but here the un-dressed face of each piece catches the light. It started life as a limestone, but was recrystallised as marble by heat and pressure - a metamorphic rock, of Jurassic age.</p><p><a href="https://tech.lgbt/tags/Geology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Geology</span></a> <a href="https://tech.lgbt/tags/UrbanGeology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>UrbanGeology</span></a> <a href="https://tech.lgbt/tags/Marble" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Marble</span></a> <a href="https://tech.lgbt/tags/CarraraMarble" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CarraraMarble</span></a> <a href="https://tech.lgbt/tags/Texture" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Texture</span></a> <a href="https://tech.lgbt/tags/Metamorphic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Metamorphic</span></a> <a href="https://tech.lgbt/tags/Jurassic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Jurassic</span></a> <a href="https://tech.lgbt/tags/Birmingham" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Birmingham</span></a></p>

Urban Geology<p>This side project started on the bird app pre-covid, but turned out be pretty fun and useful during home office, lockdowns and quarantine and got more attention than I imagined. 😁 Just keep your eyes open and look out for geology around you, no matter if at home or in the city.
