金山店矿田从50年代开始找矿勘探,现已探明相当丰富的工业储量.但进一步找矿的潜力如何?矿床分布规律怎样?找矿最佳部位在哪里?迄未解决.本文试图运用数学地质方法探讨这些问题. 矿田地质概况本区位于淮阳地盾与雪峰地盾间台缘褶皱带西端的大冶复式向斜中.金山店侵入体横贯全区,呈北西西-南东东向分布,为燕山晚期浅成至中深成相的岩墙状岩体.侏罗系和三迭系地层构成岩体围岩.矿田西南分布白垩纪喷发的流纹岩、凝灰岩和火山角砾岩. 三迭纪末至白垩纪,本区经历了多次构造变动,褶皱和断裂均较发育.主要构造线呈北西
The Jinshandian orefield has been looking for ore exploration since the 1950s and has already proved quite rich in industrial reserves. However, what is the potential for further prospecting? How is the ore deposit distribution? Where is the best place for prospecting? Mathematical geology methods to explore these issues.Geological overview of the minefield This area is located in Dayev double syncline in the western edge of the platform margin fold belt between Huaiyang Shield and Xuefeng Shield.Jinshandian intrusion penetrates the whole area and is in the northwest-south East-East distribution, which is the shallow-medium to deep-phase rock-domed rock mass in the Late Yanshanian.The Jurassic and Triassic strata constitute the rock mass surrounding rock.The southwestern distribution of the Cretaceous rhyolites, tuffs and tuffs Volcanic breccia. From the end of Triassic to the Cretaceous, the area underwent several tectonic movements with relatively developed folds and faults. The main tectonic line was northwest
