Rock 365 : Day 5


Day 5 : The first of my deskcrops.  This sample of otherwise unremarkable fine-grained grey rhyolite has an important minor component – there is gold in that there rock. The small light coloured specks are native gold.  The rock is from El Guanaco Mine, Santa Catalina, Antofagasta Province, Antofagasta Region, Chile
