| 摘 要： | 位于辽宁省宽甸县大西岔乡的东挂牌岭硼矿,处于杨木杆复式向斜构造南翼,含硼层位赋存于里尔峪组中下部,呈层状、似层状展布。地表赋矿层在走向和倾向上都具有膨缩现象。通过与邻近庙沟矿区的矿体特征、构造等成矿条件综合对比,二者均发育有大范围含矿层,且含矿层规模较大,同时严格受蛇纹石化镁橄岩层控制,为层控矿床;地表蚀变均较强烈,蛇纹石化较普遍。普遍存在较大规模的北北东向逆断层,赋矿层受此构造影响,普遍向深部侧伏等方面非常相似。通过地表及浅部钻孔(350m以上)控制,认为矿体具有一定的厚度和品位,在走向、倾向上延伸均较好,在倾向上有增厚的趋势。故推测东挂牌岭西区深部资源前景巨大,有望通过进一步工作,取得找矿突破。

| Abstract: | Located at the south limb of Yangmuxuan multiple syncline at Daxicha village,Kuandian county,Liaoning province,the expanded and shrinkable layer and layer-like Guapailing boron bearing layer were host at the middle-underpart of Lieryu group.Be contrasted with near Miaogou orebody Characters and structure,east Guapailing boron rock has the same geological characters with it,such as large scale ore-bearing layer,be controled by serpentinization forsterite strata,strata-bound deposit,strong surface alteration and serpentinization,large scale NNE reverse fault and with raking deep host-layer.We found the host layer has the same pinch,expanded and shrink characters with the region,and the deeper one are thick and with some high grade and entend long for strike and trend,all of which shows that the west area of east Guapailing have the better prospecting foreground. |
