Orogenic gold deposits: A proposed classification in

1998-4-1  Most deposit types that contain ore-grade gold,whether with gold as the principal metal or together with copper, are sited along convergent plate margins (Sawkins, 1990). There are notable exceptions, such as gold-rich volcanogenic massive sulfide deposits developed along spreading ocean ridges (e.g. Bousquet) and other deposit styles associated with possible anorogenic hot spots (e.g.

Gold Deposits and Their Geological Classification

2016-11-20  The development of a simple classification scheme for gold deposits, as presented here, has been approached with a full appreciation that there are many difficulties associated with classification of ore deposits in general. In the case of lode gold deposits, contrasting classifications and nomenclatures have been arrived at historically depending on

1) To render barren the upper parts of many ore deposits. 2) To change minerals into more usable or less usable form or to make rich bonanzas. 3) Supergene enrichment may add much where there was little. 4) Leaner parts of the vein may be made rich. 5) Unworkable protore may be enriched to the ore grade. E.g. many of the copper districts would not have come into existence except for the process of enrichment.
