| 摘 要： | 由余家园、李家湾、石庄、拔茅山铜矿带环绕皂树咀辉石粗安玢岩体与上侏罗统砖桥组火山岩系地层内外接触带附近构成未封闭的环状矿带，具面状蚀变，铜草发育，矿化多呈细脉浸染状，地表矿化普遍较强，寻找与拔茅山铜矿类似近接触带细脉浸染型带状斑岩型铜矿具一定潜力。

| Abstract: | The Yujiayuan, Lijiayuan, Shizhuang and Bamaoshan copper ore belt circles the inner and outer contact zone between the Zaoshuzui pyroxene trachyandesitic porphyrite intrusion and the upper Jurassic Zhuanqiao Formation of volcanic strata, forming an unclosed circular metallogenic belt with planar alteration, well-grown copper flowers, veinlet disseminated mineralization, and extensively strong surface mineralization. There is potential to prospect veinlet disseminated banded porphyry copper ore deposit similar to the Bamaoshan copper ore near the contact zone. |
