CLASSIFICATION OF DEPOSITS - Earth Sci

2017-6-26  Magmatic deposits are syngenetic in that the ore minerals crystallize from the same liquid that produces the silicate minerals which form the bulk of the intrusive - they crystallize more or less simultaneously as the melt cools.

Ore Deposit - an overview ScienceDirect Topics

Ore deposits are rarely comprised of 100% ore-bearing minerals, but are usually associated with rock-forming minerals during the mineralization process. These associated minerals or rocks, having no significant or low commercial value, are called gangue minerals. Pure chalcopyrite having 34.5% Cu metal in copper deposit and sphalerite with 67% Zn metal in zinc deposit are hosted by quartzite ...

Magmatic ore deposits (Chapter 2) - Ore Deposit Geology

Magmatic ore deposits, also known as orthomagmatic ore deposits, are deposits within igneous rocks or along their contacts in which ore minerals crystallised from a melt or were transported in a melt. Ore deposits that form in and around igneous rock units as a result of mineral precipitation from aqueous solutions or hydrothermal fluids are hydrothermal ore deposits.

Morphology of ore deposits and their relations with host

a) Disseminated deposits: In these deposits, the ore minerals are dispersed throughout the body of the host rock e.g. diamonds in kimberlite. In other deposits, the disseminations may be mainly along close-spaced veinlets cutting the host rock and forming an intercalated network called a stockwork.
