Mining in Manitoba |
Geological Considerations |

Ore occurs in many forms and is associated with mant types of geologic structures. The geologic conditions and ore occurrence are major factors in determining the type of mining method. Knowledge of the geology of a deposit will help the mine operators in the actual mining and may help to discover new ore deposits. A magma may be considered as a hot, fluid, subterranean mass that contains the common rock-forming elements, different gases, such as water vapour, carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur, chlorine, fluorine, boron, and the various metals. During cooling, a magma differentiates or splits into mineral components that give rise to BASIC and ACIDIC phases of igneous rocks and to a residual mother liquor which is the principal source of ore minerals |
