摘　　要：图拉尔根铜镍矿位于东天山黄山-镜儿泉铜镍成矿带的东段,是近年来新发现的具大型成矿远景的岩浆型铜镍硫化物矿床。通过系统研究区域成矿地质环境、矿床特征、地球物理特征、地球化学特征等找矿信息的基础上,对图拉尔根铜镍矿床不同尺度的地质、物探、化探等致矿地质异常信息进行提取,在地质异常理论指导下,尝试性地建立了图拉尔根铜镍矿基于"5P"找矿地段圈定的多源信息找矿模型,初步确定了不同找矿地段的地质、物探、化探模型要素组合,提出了以"基性-超基性杂岩体+高磁、高极化、高重力、低电阻+Cu、Ni、Co综合异常+褐铁矿化、孔雀石化"为核心的矿床综合信息找矿模型,对于野外地质找矿具有指导意义。Tulargen Cu-Ni sulfide deposit, located in the eastern part of Huangshan-Jinerquan Cu-Ni metallogenic belt in Eastern Tianshan, is a newly discovered large scale deposit related to mafic-ultramafic complex in recent years in Xinjiang. By systematic research on various ore-prospecting ge- ological infornmtion, such as regional metallogenic geological settings, geolocical characteristics of the deposit, geophysical and geochemical characteristics, we extracted different scale geological, geophysical and geochernical anomalies information associated with mineralization. Under the guidance of geo- logical anomaly theory, we established multi-source information prospecting model of Tulargen Cu-Ni sulfide deposit based on ＂5P＂ method for approach the target, and preliminary determinined geological, geophysical and geochemical modeled element combination in different exploration area, and then, the author proposed comprehensive information prospecting models of Tulargen Cu-Ni sulfide deposit centered on mafie-ultramafie complex ＋ high magnetic a- nomaly＋high polarization ＋hypergravity＋low resistance＋Cu-Ni-Co composite anomaly＋limonitization and malachite, it has some guiding meaning for field geological peospecting.
