Abstract: | The authors discussed the metallogenic conditions of gold-bearing skarn deposits along the middle-lower Yangtze River reaches.
Gold was enriched in mantle-originated magmas while copper was enriched in crust-originated magmas. So the enrichment of gold
in skarn deposits was decided by the M/C ratios of the intrusive rocks. The distribution of these deposits was controlled
not only by the localization of the intrusive rocks which were decided by Mesozoic Era-developed large-scaled and deep-seated
faults, but also by the favorable stratigraphic horizons.
Synopsis of the first author Zhang Shugen, associate professor, born in 1958, received Ph. D degree in 1993, majoring in ore deposit and geochemistry,
has published 44 papers. |
