| 摘 要： | 后仙峪硼矿区地表分布的岩石主要为混合花岗岩.前人研究认为该岩石为岩浆岩,其下不可能存在层控硼矿床.通过对该区地质资料及混合花岗岩的分析研究,结合多年野外勘查工作,得出该岩石为正常地层,经钻探验证在数百米厚混合花岗岩层下发现了隐伏硼矿体,取得了找矿突破,扩大了该区找矿前景.

| Abstract: | The Houxianyu boron ore field,tectonically located in the west end of the Yingkou Kuandian paleo uplift of Eastern Liaonign anteclise,North China platform,is a part of the East Liaoning South Jilin boron metallogenic belt.The studied area is essentially covered by migmatitic granite,which was regarded as magmatic rock by previous researchers.By the study and regional comparison of the distribution,lithology,petrochemistry and geochemistry of the rock,the authors consider that the migmatitic granite is formed by sedimentary metamorphism.It is a normal metamorphic stratum,but not magmatite.There probably exist stratabound boron ore bodies beneath the rock.The drilling test has proved a buried boron ore body under the hundreds meters of thickness of the migmatitic granite,making a breakthrough in the exploration and adding the potential of prospecting in the area. |
