摘要
在系统统计湘南地区出露地层(震旦系至侏罗系)各类岩石成矿元素丰度(A)、总体平均含量(M)、浓集克拉克值(K)和叠加强度参数(M/A)基础上,结合湘南地区成矿特点,分析了W,Sn,Pb,Zn和Sb等元素的成矿作用.初步认为在湘南地区仅沉积作用、海底火山作用及热卤水作用难以形成上述元素的大型矿床,但通过沉积改造、热液叠加作用有可能形成层控型铅。
The abundance(A),concentration clark(K),total average concentration(M) and M/A ratio of the chemical elements in the (Sinian to Jurassic) sedimentary cover are calculated.The result suggests that sedimentation and hydrothermal activities played an insigificant role in the formation of large-scale ore deposits in the region.But they might have led to the formation of small-scale sedimentary and reformed type of lead,zinc and antimony deposits.
