a piece of ocean’s crust …

Joides Resolution on the core deck…

… a great moment, the Rockers are investigated a core of ocean’s crust !

I have already seen rocks like gabbro, basalt but never a piece of the crust coming from the Juan de Fuca ridge.

I can show you some sections of the core, find the right legends ! and the good sequence …

 

legends : dolerite / pyrite formation / contact gabrro and basalt / basalte with hematite
