#ThinSectionThursday No fancy minerals in today's rock, but it does feature clear skeletal plagioclase crystals looking like a wee propeller & a wee hand pointing upwards (or giving the finger?? 😁 ) The rest of the rock is brown glass, with finely dendritic-skeletal magnetite and clinopyroxene. From Scobull, on the Isle of Mull. Field of view 2mm wide. #Geology #Microscopy #quenching #Supersaturation #Mull

"Our simulations predict that frequent cycling of a solution between #supersaturation and undersaturation can accelerate #dolomite growth by up to seven orders of magnitude. We validated our theory with in situ liquid cell transmission electron microscopy, directly observing bulk dolomite growth after pulses of dissolution. This mechanism explains why modern dolomite is primarily found in natural environments with pH or salinity fluctuations."
