摘　　要：大厂矿田孕育了世界瞩目的大型锡多金属矿床,巴力—龙头山矿区是大厂矿田的重要矿区之一,文章通过地质勘查和对矿床地质特征、成矿条件进行分析研究,认为100号与105号主矿体共同构成了缓-陡-缓“S”形螺旋状矿体,预示着隐伏花岗岩体的侵入方向,是自南东向北西向侵入的;在“S”形螺旋状矿体边部,仍有平行矿体存在的可能性;生物礁灰岩的底板下,成矿潜力巨大;隐伏花岗岩的侵入面同样是找矿突破的重要区域。The Bali—Longtoushan deposit is one of the important mining areas of the Dachang ore field,which has bred a large-scale tin polymetallic deposit,and attracted worldwide attention.Based on the research of geologic feature,metallogenic condition and the results of geological exploration,it’s considered that No.100 and No.105 main orebodies together constitute a“S”-shaped spiral ore body.This indicates the intrusion direction of the concealed granite body is from southeast to northwest.There is still the possibility of parallel orebodies at the edge of the“S”-shaped spiral orebody.There are great ore potentials under the floor of the reef limestone.And the intrusive surface of the concealed granit is an important area for prospecting breakthrough.
