Ore genesis - Wikipedia

Endogenous Magmatic processes. Fractional crystallization: separates ore and non-ore minerals according to their crystallization temperature.As early crystallizing minerals form from magma, they incorporate certain elements, some of which are metals.These crystals may settle onto the bottom of the intrusion, concentrating ore minerals there. Chromite and magnetite are ore minerals that form in ...

Stormwater plays an important role in the hydrolysis and oxidation processes within the rocks. Stormwater can become a bit acidic by absorbing carbon dioxide in the atmosphere and as such this activates chemical action with the mineral granular particles in the rock producing chemical compounds such as salts and minerals that dissolve or eats away the rocks.

Classification of Mineral Deposits | Geology for Investors

Jul 29, 2013· Most mineral deposits are formed by more than one process, so attaching a single label to them is difficult. Hence, there is a tendency to talk about Stillwater Complex type or Carlin-type gold deposits, which rather defeats the purpose of finding a general from the specific.

Mineral deposit - Formation of mineral deposits | Britannica

Formation of mineral deposits. Mineral deposits form because some medium serves as a concentrating and transporting agent for the ore minerals, and some process subsequently causes the transporting agent to precipitate, or deposit, the minerals. Examples of concentrating and transporting agents are groundwater, seawater, and magma; examples of precipitating processes are boiling (as …

Soils – Fundamental Concepts

Soils have four major components: (a) mineral matter, (b) organic matter, (c) air, and (d) water. Air and water occupy the pore spaces in soils. Pore spaces are the voids between the soil particles. Air and/or water occupy approximately half the volume of soil. Fine-textured soils have more total pore space than coarse-textured soils.
