54
process where a partly crystallized magma is subjected to stress, the fluid fraction is squeezed off from the residual crystalline mush.
Filter Pressing
55
materials is forced into the surrounding rocks, the process is called
Magmatic Injection
56
If ore is present, it is called
magmatic injection deposit
57
Oxides or sulfides dominated magma or magmatic fractions that solidify directly as ore is called
Ore magma
58
formed from continuous cooling, differentiation and crystallization of intermediate to silisic magmas.
Hydrothermal Fluids
59
hot-water solution carrying dissolved mineral substance
Hydrothermal fluids
60
Any water that passed thru & equilibrated with the atmosphere
Meteoric Waters
61
Temperature and consequently solubility of mineral increases as this water percolates down
Meteoric Waters
62
involved in formation of evaporites, phosphorites, submarine exhalatives, Mn nodules & oceanic crust deposits
Sea Water
63
medium of dispersion of dissolved ions, molecules, and suspended particles.
Sea Water
64
“fossil water” trapped in sediments at the time they were deposited
Connate Water
65
sinking of globules of a heavy liquid formed by immiscibility within and from a parent liquid after some differentiation
late-liquid gravitative accumulation
66
residual liquid is squeezed out into the surrounding rocks
magmatic injection
67
