Metamorphism/Metasomatism
Hydrothermal process
Exogenous Processes
Weathering & Supergen enrichment
Chemical deposition
Mechanical concentration

2. With an ore body 4km long and 80m wide and lying at a depth of 2km, Kiruna is one of the world’s largest, most modern underground iron ore mines. At present, approximately 800Mt of ore, only one third of the original ore body, has been extracted.

3. EL LACO MAGNETITE DEPOSIT
Bedded hematite ash and lappilli. This deposit is composed of loose, uncemented, material that can be dug out by hand..

8. Plate Tectonics and Mineralization

10. Distribution of major tectonic plates

15. Classifications of Mineral Deposits

16. Simple genetic classification of minerals deposits
Magmatic mineral deposits concentrated in igneous rocks;
Residual mineral deposits formed by weathering reactions at the earth’s surface.
Placer deposits are sorted and distributed by flow of transporting media such as water, wind and ice;
Sedimentary mineral deposits are precipitated from a solution, typically sea water;
Metamorhogenic mineral deposits form in association with metamorphism
Hydrothermal mineral deposits form in association with magma and water;
