摘　　要：对遂昌治岭头金矿床 3个矿段 (东矿段、中矿段、西矿段 )的黄铁矿进行了化学成分标型特征的研究。指出黄铁矿中铁、硫主元素的含量 ,钴、镍含量及比值 ,硒、碲含量及比值均为本矿床的成因系沉积后经热液叠加提供了比较可靠的依据。黄铁矿中的 w( Cu) /w( Zn)、w ( Ag) /w ( Zn)、w ( Pb) /w ( Zn)值为本矿床提供了成矿信息 ,认为西矿段见矿部位矿体向下延伸要大于中矿段 ,指出了进一步找矿的前景。Chemical typomorphic characteristics of the pyrites on three ore blocks from Zhilingtou gold deposit of Suichang County in Zhejiang Province are studied.It is shown that the contents of main elements Fe,S and trace elements Co,Ni,Se,Te in pyrites and their ratios of w (Co) to w (Ni), w (Se)to w (Te) can provide relative reliable basis for the genesis of the gold deposit which is hydrothermal superposed deposit after the sedimentation.The ratios of w (Cu)to w (Zn), w (Ag)to w (Zn) and w (Pb)to w (Zn) provide ore forming information.The author thinks that the ore body extension of discovery ore position on the western ore block is deeper than that on the central ore block and shows the possibility of prospecting further.
