Rotating cute cartoony plagioclase grain

I may have just discovered the true worth of LLM image generation… #thinsection #plagioclase #geology

Unlike Sunstone Knoll which is quite tholeiitic, such #plagioclase megacryst porphyritic lavas of my home island of #Oʻahu are transitional between #calc-alkaline and #alkaline. We have one calc-alkaline flow formed via hydrous anatexis, the Mauna Kūwale rhyodacite.

Sunstone Knoll, a dual-vented Pleistocene compound cinder cone of the Ice Springs Subfield of the Black Rock Desert Volcanic Field. #Plagioclase -phyric tholeiitic basalt erupted here has the highest Y of BRDVF basalts which may be the source of reported flourescence of those labradorite under LWUV.
