    河南马超营—独树一带银铅锌成矿地质条件及找矿前景

    Ore-forming geological conditions and ore prospects of silver-lead-zinc-gold deposits in the Maochaoying-Dushu area, Henan

    • 摘要: 提要: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: Abstract: The Maochaoying-Dushu area on the southern margin of the North China block is a Proterozoic-Paleozoic aulacogen, where there occur littoral, neritic and shelf continental-margin clastic-carbonate formations of the Guandaokou Group, Luanchuan Group and Taowan Group. Strong shallow-source volcanic eruption (exhalation) gave rise to multi-layer chert bands (nodules), siliceous rocks and silver-lead-zinc mineralization-bearing layered skarn in the area. This area is a relatively typical district where a geochemical abrupt change zone and a geophysical gradient zone intersect. The earth's mantle and crust beneath the area are enriched in Mo, Pb, Zn and Au. From the ore-forming geological conditions of silver-lead-zinc-gold deposits, it is inferred that the area has good ore prospects.
