Classification of Ore Deposits. No two ore deposits are the same! However, they can be divided into broad classes eg syngenetic (BIF) vs epigenetic (vein) 10 Discordant Orebodies. Regularly shaped bodies ; Tabular veins, faults. Divides footwall and hanging wall ; Tubular pipes or chimneys (vertical) and mantos (horizontal) Irregularly shaped

Lecture 1: An introduction to minerals, ore and exploration

Ore is rare in the crust. The geological formation processes are several and often complex, and no ore body is the same. Trying to find ore is called mineral exploration, or just exploration. Exploration is done in many steps, and often takes several years or even decades before an ore body can be defined and potentially mined.

May 07, 2015 A “shear zone” is a wide zone of distributed shearing in crushed rock mass with width varying between few centimeters and several kilometers. The interconnected openings of shear zone serve as an excellent channel ways for mineral-bearing solutions and subsequent formation of deposits. Many shear zones in orogenic belts host ore deposits.

Lead-Zinc Ore deposits (MVT ores). The mechanism of formation is remarkably similar to that of the other hydrothermal deposits. Groundwater seeps downward through sedimentary rocks and gets a little bit warmer as it sinks. There is no hot magma source. This heating is due entirely to the geothermal gradient, which is a natural consequence
