The concentration of minerals within a body of rock
Local concentration of metallic minerals.
(3) the processes taking place in the earth's crust resulting in the formation of valuable minerals or ore bodies.
the natural process by which sometimes valuable minerals are aggregated, resulting in a potential ore deposit
The concentration of metals and their compounds in rocks, and the processes involved therein.
Minerals occurring in rocks, generally of value if found in sufficiently high concentrations.
rock containing an undetermined amount of minerals or metals.
a natural aggregate of one or more valuable minerals.
The process or processes by which mineral or minerals are introduced into a rock, resulting in a valuable or potentially valuable deposit.
The formation of minerals. New minerals may be added to fractures and empty spaces in a rock or by replacing preexisting minerals with different ones.
A natural aggregate of one or more metallic minerals.
