Intracontinental layered intrusions, hosting magmatic ore deposits, have the closest link with mantle plumes. By far the best example of the great layered intrusions is the Bushveld Igneous Complex in South Africa, which is undoubtedly the largest repository of Cr, PGE and V in the :// Nickel Sulfide Ores and Impact Melts: Origin of the Sudbury Igneous Complex presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada.

Page - A conspicuous illustration of ore-deposits of this class which may be mentioned are the metallic copper deposits of the Lake Superior region. The copper was in all' probability reduced and precipitated directly as metallic copper from upward moving cupriferous solutions.

Some deposits are related to metamorphic processes and are as such classified as deposits of metamorphic origin. Within these three broad modes of origin, a mineral deposit of economic value might have originated due to set of simple or complex processes.

Describe the processes that act to form igneous Metallic ore deposits can form wherever there is igneous activity, due to either vulcanism certain pH conditions, so increased acidity in surface water can harm ecosystems. Also, /activities/ Syngenetic deposits of igneous origin are usually less regular than sedimentary beds.
However in some thick sills and lopoliths, the rock constituents have a very regular stratiform arrangement. 2 In Epigenetic deposits Ore that has been introduced into rocks may show strain partiality to certain formations whether the ore follows fractures or replaces formations :// IN an earlier communication to NATURE (April 3,p.

A deposit is economically viable only if a certain element occurs in a substantially higher concentration than in the average rock of the earth's crust.

Prof. Louis quotes the following sentence: ``It would perhaps be too much to say in the present state of our knowledge that all primary ore-deposits are of igneous origin, but this is a view which may very likely 12R/abstract.

Introduction. The Sudbury Igneous Complex (SIC) contains the second largest known concentration of magmatic Ni-Cu sulfide mineralization after Noril’sk in Russia (Lightfoot, ).The ore deposits at Sudbury were formed by the segregation and settling of dense immiscible sulfide from a melt sheet generated by a catastrophic impact event at Ga (Keays and Lightfoot, ).
This book "presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada. As the first complete reference on the subject, this book explores the linkage between the processes of meteorite impact, melt sheet formation, differentiation, sulfide immiscibility and metal collection, and the localization of ores by magmatic and post A compilation of quartz veins or dikes of igneous origin has been pub-lished by Tolman ().
He excludes quartz veins that contain metallic ore deposits, but does mention auriferous quartz veins in Victoria, Aus-tralia, which are believed to be of pegmatitic origin because of the pres-ence in varying amounts of feldspar, muscovite and Willemse J (a) The geology of the Bushveld Igneous Complex, the largest repository of magmatic ore deposits in the world.
