摘　　要：塔拉特铁铅锌矿床产于下泥盆统康布铁堡组下亚组第二岩性段上部,容矿岩石为中酸性变质火山碎屑岩,矿体沿走向、倾向延伸稳定,浅部矿体较薄,深部有变富、变厚趋势。主产元素铅、锌,伴生铁、银、铜等。矿体受火山喷发机构和地层层位控制,有火山喷流—沉积成矿特征,属海相火山岩型铁铅锌矿床。根据对该矿床地质特征及成矿规律的分析,认为该矿床下一步找矿方向主要为A4矿段及A3矿段的深部。本文提出的找矿认识,对指导该矿床下一步勘查工作具有重要的意义。Talate iron-Pb-Zn deposit occurs in upper 2nd lithological member of Lower Devonian Kangbutiebao Formation Team, with the host rocks of neutral-acdic degenerative pyroclastic.Ore bodies extend steadily along, strike and dip.The Ore body in the superficial part is relatively thin, while it become abundant and thick in deep part.The staples are lead and zinc; ubordinate production are iron,silver,copper,etc.. The ore body is controlled by volcano eruption body and stratigraphic position, having the characteristic of volcano jet-flow-precipitation mineralization and belonging to sea facing volcano type iron-Pb-Zn deposit. On the basis of analysis on the deposit geological characteristics and regularity of ore formation,it is considered that the next prospecting range is mainly the deep part in A4 and A3 ore block in this deposit. This viewpoint put forward in this paper is very significant for helping next mine exploration.
