摘要
大岩子-清水河地区的1∶5万Pt-Pd水系沉积物测量表明,大岩子Pt-Cu矿床的指示元素有Pd、Pt、Au、Cu、Ni、As、Ag、Cd、F、Hg、Pb、Zn、S和Se,地球化学异常具有水平分带的特征,即从矿床向外的异常元素依次为Pd、Pt、Au-Cu、Ni-As、Ag-Cd、F、Hg-Pb和Zn。试验研究表明,1∶5万水系沉积物测量是找寻Pt、Pd矿床的有效方法。推测西王庙周围有Pt、Pd矿的找矿远景。
A stream sediment survey with scale o f 1∶50000for the plat inum group elem ent (PGE)deposit was conducted.The results shows that th e in dicator elements of the Dayanzi Pt-Cu deposit are Pd,Pt,Au,Cu,Ni,As,Ag,C d,F,Hg,Pb,Zn,S,and Se.The sequence of horizontal zoning of those geochemi cal anomalies(from deposit to wall rock)is from Pd,Pt,Au-Cu,Ni-As,Ag-Cd ,F ,Hg-Pb to Zn.This study also shows th at the stream sediment survey with scale of 1∶50000is a effective method for exploring the platinum group el ement (PGE)deposit.It is inferred from geochem ical survey on Dayanzi-Qingsh uihe b elt that the Xiwangmiao area may have prospective for PGE deposit.
