| 摘 要： | 马超营－独树一带位于华北陆块南缘，为一元古宙－古生代裂陷槽。官道口群、栾川群和陶湾群为滨海、浅海、陆棚相陆缘碎屑－碳酸盐岩沉积建造，强烈的浅源火山喷（气）发活动，形成多层硅质条带（团块）、硅质岩以及含Ag、Pb、Zn矿化的层状夕卡岩带。该带是比较典型的地球化学急变带与地球物理梯度带交叉区，壳、幔富含Mo、Pb、Zn、Au元素。基于该带银铅锌金矿成矿地质条件，推断具有良好的找矿前景。

| Abstract: | The Maochaoying-Dushu area on the southern margin of the North C hina block is a Protero-zoic-Paleozoic aulacogen,where there occur littoral ,neritic and shelf continental-margin clastic-carbonate formations of the G uandaokou Group,Luanchuan Group and Taowan Group.Strong shallow-source vol-c anic eruption(exhalation)gave rise to multi-layer chert bands(nodules),sil iceous rocks and silver-lead-zinc mineralization-bearing layered skarn in th e area.This area is a relatively typical district where a geo-chemical abrupt change zone and a geophysical gradient zone intersect.The earth's mantle and crust be-neath the area are enriched in Mo ,Pb,Zn and Au.From the ore-form ing geological conditions of sil-ver-lead-zinc-gold deposits,it is inferr ed that the area has good ore prospects. |
