摘　　要：通过对小柳沟钨钼多金属成矿区十多年积累的找矿信息的综合研究,获得了关于本区成矿系统与找矿规律的系统整体认识。提出该成矿区成因类型属于多矿源改造、多期岩浆热液成矿型。受到地层、岩性、构造、多期岩浆活动等综合因素的有效组合、匹配和控制,在元古宇镜铁山—朱龙关裂谷带中,演化形成小柳沟钨钼多金属热液成矿系统。系统成矿空间巨大,成矿层次清晰,成矿分带与富集载体明确,具有良好的找矿远景。对此,提出了整体勘查靶位、靶体与策略。Based on more than ten years prospecting information in the Xiaoliugou W - Mo poly - metallic mineralizing region, systematic understanding on mineralizing system and prospecting roles is obtained. It is proposed that genetic type belongs multi ore source transformation and multi stage magmatic hydrothermal mineralization. Controlled by strata, lithology, structure and multi stage magmatic activity, Xiaoliugou pelymetallic hydrothermal mineralization system is formed in the Proterozoic Jingtieshan - Zhulongguan rift belt. The mineralizing system has huge mineralization space, distinct mineralization unity, clear mineralization zonation and ore - rich carrier, and good ore prospecting. Ensemble investigation target position, target body and strategy are proposed.
