42
Q

conduit

A

cracks and spaces in the rock where fluid flows

43
Q

cracks and spaces in the rock where fluid flows

A

conduit

44
Q

gasses in hypogene

A

various gasses are released by the magma and transpoted in the water, they react with the metals in the water to produce sulfides.

45
Q

Supergene enrichment process

A

Once the heat source cools off, water traveling downwards turns sulfides into oxides, and creates highly enriched sulfides at the water table

47
Q

host rock transformation

A

as the mineral rich water flows through the conduit, it may cause changes in nearby rocks
