| 文章通过路线矿产检查、高精度磁法测量、激电中梯、土壤综合剖面测量、槽探等多种工作手段对庙沟铅锌多金属矿床进行了综合研究,得出以下认识:(1)庙沟铅锌多金属矿床由3条铅锌多金属矿体组成,呈似层状、脉状赋存于高家峪岩组中,走向北西,倾向北东,倾角45°～50°,主体赋存于地层及构造裂隙中,含矿岩性为破碎蚀变岩。(2)矿体长度50～100 m不等,厚度约1～5 m,最大延深小于200 m,矿石品位:Au 3.45×10-6～9.39×10-6,Ag 20×10-6～983×10-6,Pb 0.26%～26.3%,Zn 0.23%～16.10%。(3)庙沟铅锌多金属矿床是受断裂构造和地层控制的岩浆热液改造破碎蚀变岩型矿床；最终确定庙沟外围的东沟地区成矿潜力较大,可作为下一步工作的找矿方向。 |

| This work conducted route geological survey, high-precision magnetic measurements, IP intermediate gradient measurements, comprehensive soil profile measurements and trenching engineering to study the Miaogou Pb-Zn polymetallic deposit in eastern Liaoning Province. It is conclude that:(1) This deposit consists of three Pb-Zn polymetallic orebodies hosted in the Gaojiayu Formation with stratiform or veined occurrence. The orebodies trend NW with an inclination of 45°～50°, and are hosted in stratum and tectonic crack. The ore-bearing rocks are fractured altered rocks. (2) The orebodies vary from 50 to 100 m in length and from 1 to 5 m in thickness, with a maximum depth less than 200 m. The ore grade is 3.45×10-6～9.39×10-6 for Au, 20×10-6～983×10-6 for Ag, 0.26%～26.3% for Pb, and 0.23%～16.10% for Zn. (3) This deposit is a magmatic hydrothermal transformed fractured altered rock type deposit controlled by fault structure and stratum. The Donggou area at the periphery of Miaogou is suggested to have great metallogenic potential, which can be used as the prospecting direction for the next step. |
