【摘要】 钢铁是现代化工业最重要和应用最多的金属材料,我国正处于经济飞速发展的阶段,对钢铁资源的需求日益剧增。为寻找铁矿资源,选择鲁西贾庄地区开展成矿预测。本次铁矿预测主要目标是矽卡岩型铁矿,预测目的是圈定成矿靶区一处,确定靶区位置、面积、预测深度。本次研究内容主要为区域及研究区成矿地质、地球物理特征,典型矿床特征、成矿预测模型、找矿标志。本次研究的主要手段是资料收集与综合研究、数据库建设与数据分析、野外验证。本次运用的GIS软件是Mapgis、Arcview。研究区位于山东省苍山县贾庄一带,大地构造属华北板块鲁中隆起尼山凸起东南部。地层出露主要为古生界、新元古界碳酸盐岩、碎屑岩和新太古界变质岩,第四系覆盖严重。区内断裂构造发育,岩浆活动较强烈,尤其是燕山期中、基性杂岩体与矽卡岩型铁矿关系密切。通过研究,最终圈定了贾庄矽卡岩型铁矿找矿靶区。靶区位于贾庄乡北部,长1.8km,宽200～600m,面积0.6km2,预测成矿深度为地表至431～600m。靶区位于燕山期岩浆岩与寒武系灰岩等接触带、北东向断裂三者结合部位,找矿前景较好。本次研究是GIS高新技术在鲁西铁矿集中区的首次应用,研究结果表明,利用GIS技术开展成矿预测效率高,效果好,成本低。更多还原

【Abstract】 Steel is the most important and the most widely used of metal in modern industry.The rapid economic development in China results in a increase of steel demands. to find iron resource,metallogenic prognosis.is started in Jiazhuang regions in the west of Shandong province. The main objective is to predict skarn-type iron ore, the forecast aim is to delineate an ore target, and then determine the target location, area and forecast depth.The main research contents are the geological and geophysical features,the characteristics of typical deposits, the model for Metallogenic Prognosis and the prospecting mark in regional and study area.The major methods are data collection and comprehensive research, database construction and data analysis, and field verification. The use of GIS softwares are Mapgis and Arcview.Study area is located to Jiazhuang town, Cangshan county, Shandong Province, is southeastern part of North China tectonic plates Luzhong Swell and Ni mount raised. The strata are mainly exposed the carbonate rocks, clastic rocks of Paleozoic and Neoproterozoic,metamorphic rock of Late Archean,and a large number of Quaternary. rift is growing, magma activity is strong. especially intermediate and basic complex bodys of Yan shanian are close with skarn iron ore.By studying,finally delineate the target of Jiazhuang skarn type iron ore. The target area lies in the north of Jiazhuang town, the width is 200 metres to 600 metres and the length is 1.8 kilometres ,and area is 0.6km2. The favorable metallogenic depth is 431 to 600metres from the surface to the ground floor. Target locates in the binding sites of Yanshanian magmatic rocks, contact of Cambrian limestone and the north-east fault, forming favorable conditions.This study is the first application the GIS as high-tech in the iron ore clusters of the western of Shandong.This study showed that the ore prediction of using GIS technology is efficient and low cost.更多还原
