Ore Deposits part 1 Flashcards
Rocks or minerals that are mined, processed and delivered at a profit
Ore
Non- valuable minerals in the ore
Gangue
Mineralized Rock that is too lean in ore minerals to yield a profit
Protore
Non- valuable portion of ore
Waste
Concentration of minerals
Mineral Deposits
Concentration of minerals which certain elements can be recovered economically
Ore Deposit / Orebody
Lowest grade, or quality of mineralized material that qualifies as economically mineable and available in a given deposit
Cut-off Grade
Average content of an element in the earth’s crust
Clarke of Concentration
Ore formed as the same time as the host rock
Syngenetic Ore
Ore formed after the host rock
Epigenetic Ore
Ore formed within the earth
Hypogene Ore
Ore formed at the earth surface
Supergene Ore
Ore formed form either magmas or fluids
Primary Ore
Ore formed as a consequence of alteration of pre-existing minerals
Secondary Ore
the study of geologic materials used by man to facilitate his task
Resource Geology
Any geological material which is of commercial value to human society
Economic Geology
Accumulations or concentrations of one or more useful substances, metalliferous or non-metalliferous that are for the most part sparsely distributed in the earth’s outer crust
Mineral Deposit
Naturally occurring solids, liquids or gases known or thought to exist in or on the Earth’s crust in concentrations which make extraction economically feasible either at present or sometime in the future
Geologic Resource
A subset of a geologic resource; that portion of an identified resource which can be extracted economically using current technology
Geologic Reserve
Believed that ores are formed by magmatic differentiation
Plutonism
Ores are direct magmatic product or are formed as a products of differentiation
Plutonism
They believe in plutonism
Magmatists
Pioneer of Plutonism
James Hutton
Pioneer of Neptunism
Abraham Werner
Believe that ore deposits were formed from sediments in a primival ocean
Neptunism
Believe that ores are formed from Sedimentary Process or Underwater
Neptunism
They believe in Neptunism
Syngeneticists
