摘要
本文讨论了土岭、石湖金矿区与成矿有关的地质体的地球化学特征及其找矿标志。认为该矿区成矿物质—Au具有多源性;As、Sb、Ag、Au、Cu、Pb、Zn、Co、Ni为找矿指示元素;Hg是远程指示元素,而Au则是直接指示元素。指示元素的轴向分带序列为:As—Ag—Sb—Cu—Zn—Au—Pb—Ni—Co,并以此建立了预测矿体埋藏深度关系式:H=38.790As/Co+442.842 LnH=0.0923Ln[(As.Ag.Sb)/(Au.Co.Ni)]+6.
The paper describes the geochemical characteristics and the indicators for prospecting for the geological bodies related to mineral deposits in the Tuling and Shihu gold mines. It is considered that Au has polygenetic characteristics; As、Sb、Ag、Au、Cu、Pb、Zn、Co, and Ni are indicator elements for prospecting; Hg is telescoped indicator element, and Au is direct indicator. Axial zoning sequence of the indicator elements is described as follows: As—Ag—Sb—Cu—Zn—Au—Pb—Ni—Co, on the basis of this, the following formulas for predicting buried depth of the ore body are established. H=38.790 As/Co+442.842 LnH=0.0923Ln[(As, Ag, Sb)/(Au, Co, Ni)]
