35
ingredients for the Hypogene recipie
ground water, heat, metal, conduit
36
Heat source for Hypogene
comes from the magma itself as it cools (Includin when it's solid but still realy warm

38
groundwater in hypogene
falls down, then rises again as it is heated. carying away metals

40
metal source in hypogene
metals that can't be incoprerated in the igneous rocks are extruded

42
conduit
cracks and spaces in the rock where fluid flows
43

conduit
44
gasses in hypogene
various gasses are released by the magma and transpoted in the water, they react with the metals in the water to produce sulfides.
45
Supergene enrichment process
Once the heat source cools off, water traveling downwards turns sulfides into oxides, and creates highly enriched sulfides at the water table

47
host rock transformation
as the mineral rich water flows through the conduit, it may cause changes in nearby rocks
