A tricolor slice of gritty Neapolitan ice cream . . . er, I mean . . . saprolite
All quartz-rich and fractured: light (vanilla) center is clean micaceous quartzite;
grey-brown (chocolate) left side looks more like garnet-mica schist;
purple-to-red (strawberry) right side appears more iron-rich.
Everything dips southeast; apparent fold is due to change from vertical to horizontal cut surface.
Vanilla-to-Strawberry transition
