This Metallogenic Map includes 1285 energy resources, solid metallic and non-metallic mineral deposits of 22 commodities in 121 countries of 6 continents of the world and established them as a data bases with a digital Architecture including 19 parameters of mineral deposits for convenient of user.
According to the dynamics of disharmonic movement of mantle-crust of the earth and the global evolution of continental divergent and accretion, we have divided 4 global tectonic background and 39 tectonic settings as well as Lau Asia, Tethys, Circum-pacific Ocean and Gondwana 4 metallogenic domains, and 21 metallogenic zones.
Under the ground of global tectonic background map, we have projected the entire data base of 1285 large-superlarge deposits on the above metallogenic domains and zones to completed the (1:25M) Metallogenic Map of Large-Superlarge Deposits of the World, which is a first sheet color map (2.5§O0.8m) in the world completed by uses.
The metallogenic regularities of large-superlarge deposits in the world. Firstly, is unity in global by endogenic, exogenic and metamorphic, as well as epigenetic in origin, especially the later one is usually to overprint or rework on the former to form super accumulation of metals. Secondly, is speciality in different metallogenic domains by 35 exceptional super large ore. Among them, the most representatives are Olympic Dam in Australia, Busnvrd Cr in South Africa, and Chuquicamata Cu in Chile, Komdok PbZn in Korea, Xikuangshan Sb and Baiyunebo REE in China, Witwatersrand Au in South Africa, and so on.
Thirdly, there are preferentiality of large-superlarge deposits as fallows: 1) preference to ore-forming elements of Cu,Au,Fe,Ag,Cr,Mn,Zn,Pb,Sb,Hg is listed at a relatively high rank to form superlarge deposits easily; 2) preference to metallogenic geological settings of available data of the world indicate that are: (1) Accretion belts along continental margins or plate convergent belts: (2) Intra-cratonic or pericontinental rifts; (3) Intra-continental tectono-magmatic complex belts; (4) Precambrian granite-greenstone belts; (5) Large ductile shear zones.
Additionally, We have proposed the special metallogeny of exceptional super large deposits is to emphasize the effect of an explosive anomaly superimposing on the normal ore-forming processes. This anomaly effect is suggested to be indicated by a strong super-accumulation of metals in a short time. we hereby propose that they were created by global thermal events in certain eons and ears in geologic history. The global thermal events are tentatively recognized as oxyatmversion (excess oxygen atmospheric event) in Archean, redoxyatmversion (lack oxygen atmospheric event) in Proterozoic-Paleozoic, and tectonosphere thermal erosion (great amount of tectonic magmatic event) in Mesozoic-Cenozoic.
