Today is #FossilFriday & I taught my humans that to be a #fossil the specimen needs to be at least 10.000 a old. That doesn't hold for this #corals, but this is basically how fossils of corals look like. We found them during #hedgewatch on the #Seychelles.

Today #GeologyWithCats. We found during #hedgewatch many #quartz veins at the #Rosstrape. They formed when #silica rich fluids circulated in #fractures that formed during cooling of the Ramberg #pluton & are now remnants of a #geothermal system.

Today 3D #PillowLava for #VolcanoThursday. Such #lava forms during underwater #eruption's & is often #basaltic. Cold #water causes formation of a skin. Following lava inflates the body until the skin ruptures & forms new pillow's.

Today: during #hedgewatch in the #Alps near the #Aletsch #glacier we found these glacial #striations. The scratches are probably from the #LittleIceAge .The glacier was much thicker. They are cut in by #rocks at the bottom of the glacier.

Today 2a ago my humans met this little #toad during #hedgewatch & found also this piece of #limestone with #fossils. The fossils are stems from #crinoids i.e. small animals also called #sealilies. We love this name

Today: last week one of the humans was on #hedgewatch in a #porcelain #cafe. I'm impawressd. One main ingredient of china is the #clay #mineral #kaolinite. Which is produced by weathering of e.g. #feldspar.

Today is #VolcanoThursday. These are #lapilli in #buildingstone. Lapilli describes the size of #tephra-a #volcanic #rock. These are accretionary lapilli-round particles formed in a wet cloud of volcanic ash. Found during #hedgewatch on the #Azores

Today #geology from my #hedgewatch on the #Seychelles. There most #rocks belong to the #granite's & exist of #quartz, #feldspar (FSP), & #mica. Granites aren't happy in warm & humid #climate's because the FSP weathers very fast away while the quartz stays longer.

Today is #VolcanoThursday 😻 During #hedgewatch on #Tenerife I found this #lava piece with bubbles. #Magma contains gas & when it travels to the surface it cools down & pressure drops so the gas is released & makes bubbles.

Today #GeologyWithCats! We found this #drillcore it's a #sandstone. The white layers had large pores with #water in it. When #sediment was accumulated the pressure was growing & finally the water was squeezed out upwards-its a water escape structure.
