福建双旗山金矿深边部成矿预测研究

Study on Prediction of Mineralization at the Depth and Edge of the ShuangqiShan Gold Geposit,Fujian Province

双旗山金矿位于武夷成矿带金矿成矿远景区内,地处闽中"金三角"地区,区内矿床(点)众多,金矿体主要受韧性剪切带控制呈层状、似层状,赋存于中晚元古代大岭组变质岩中,为韧性剪切带型金矿床。通过对成矿地质背景、典型矿床地质特征和区域成矿地质条件的研究,结合物探、化探、自然重砂等综合信息分析,并根据区域成矿地质、成矿作用及其相互关系、时空演化规律,建立成矿模式,全面利用综合信息预测方法,开展综合信息成矿规律及预测评价工作,圈定双旗山、杨梅、吉山、青溪等五个有利的成矿远景区,提出该区下步找矿方向和找矿靶区。

Abstract：The Shuangqi Shan ore deposit,a ductile shearing zone type gold deposit located in the gold metallogenic prospective region of the Wuyi metallogenic belt,occurs in the metamorphic rock of the Daling formation of middle Proterozoic in a layering or layer-like manner.Through the study on metallogenic geological background,geological features of typical ore deposits and regional metallogenic geological conditions,a metallogenic model has been established by combining the comprehensive information of geophysical,geochemical exploration and natural heavy concentrate,relationship between regional metallogenic geology and mineralization and the time-space evolvement regularity.Using the comprehensive information-based prediction method,this paper determines five prospective areas of favorable mineralization,such as the Shuanqi Shan,Yangmei,Qing Shan and Qingxi,etc.,and suggests the ore-search.direction and targets for the future survey efforts in this region.
