摘　　要：产于辽东-吉南地区裂谷盆地中的古元古界辽河群里尔峪组为一套含硼岩系。其中划分的上、中、下三个含硼岩系分别赋存硼镁石-遂安石型、含磁铁矿-硼镁石型和硼镁铁矿型三类硼矿床。硼矿的发育与地层、围岩物质成分、围岩厚度及电气变粒岩等均有一定关系。通过分析研究,划分出营口后仙峪外围、风城和宽甸3个成矿远景区。并圈定出后仙峪硼矿外围、凤城县东汤镇西山、宽甸牛皮闸—大西岔、集安太平沟—小西沟、宽甸县老阳沟等4个找矿靶区。The Liaohe Group of Paleoproterozoic Erathem located in rift basin of east Liaoning and south Jilin area, a boron-bearing Rock series which is divided into thress part from the up to bottom of this group and separatedly locate with szaibelyite--suanite ,magnetite bearing szaibelyite and ludwigite types of boron deposits. The development of boron deposit has certain connection with the stratum, the composition and the thickness of country rock, as well as the tourmaline bearing leptynite. By the working of this research ,it is divided into three prospective area ,which is the periphery of Houxianyu boron deposit, ,Fengcheng and Kuandian ,. And four prospecting target area lined out that are the periphery of Houxianyu boron deposit, the west mountain of Dongtang village of Fengcheng town , Niu pizha—Da Xicha of Kuandian village ,Tai Pinggou -Xiao xigou of Jian city.
