摘要近年来,在青海柴达木盆地周缘(简称柴周缘)地区陆续发现了一系列与超基性岩体有关的镍矿床(点)。为此,根据已有地质矿产资料,通过综合研究分析,总结了柴周缘地区镍铜硫化物矿床的成矿地质背景、空间分布及成矿特征; 在柴周缘地区划分出柴北缘高压混杂岩带、欧龙布鲁克陆块、柴南缘昆北裂陷槽及柴南缘昆中岩浆弧带等4个镍成矿区带,并重点分析了各成矿区带的镍矿床(点)成矿特征; 在此基础上,总结了柴周缘镍矿床的幔源岩浆深部熔离和上侵贯入的成矿模式及含矿岩石风化露头和物化探异常等找矿标志,圈定出柴北缘高压混杂岩带西段的阿尔金南缘茫崖镇—冷湖镇、欧龙布鲁克陆块东段的乌兰、柴南缘昆北裂陷槽西段的冰沟南和东段的夏日哈木西北,以及柴南缘昆中岩浆弧带中段的夏日哈木—托拉海南和白日其利—哈图6处镍矿找矿潜力区。所取得的地质找矿效果,对推动整个柴周缘地区与超基性岩体有关的镍矿的勘查工作具有重要意义。

Abstract：In recent years, a series of nickel deposits (points) related to ultrabasic rocks have been discovered in the periphery of Qaidam Basin, Qinghai. According to current geological and mineral data, the authors summarized the metallogenic geological background, spatial distribution and metallogenic characteristics of the Cu-Ni sulfide deposits in the periphery of Qaidam Basin based on comprehensive analysis of current geological data. The four nickel metallogenic zones(the high-pressure mélange zone and Oulongbuluke block on the northern margin of Qaidam Basin, northern Kunlun aulacogen belt and middle Kunlun magma arc belt on the southern margin of Qaidam Basin)were pointed out in the periphery of Qaidam Basin. And the metallogenic characteristics of each nickel metallogenic zone were analyzed emphatically. Besides, the authors summarized the metallogenic model of the nickel deposits (the deeper liquation and the upper intrusion of mantle-derived magma), and the prospecting criteria (the outcrop of ore-bearing rock and the geophysical and geochemical anomaly). And the six prospecting potential areas of nickel minerals, including the Mangya Town - Lenghu Town located in the southern margin of Altyn in the west of the high-pressure mélange zone on the northern margin of Qaidam Basin , Wulan in the east of Oulongbuluke Block, Southern Binggou in the west of northern Kunlun aulacogen belt, Northwestern Xiarihamu in the east of northern Kunlun aulacogen belt, Xiarihamu-Southern Tuolahai and Bairiqili-Hatu in the middle of middle Kunlun magma arc belt, were delineated. The results of geological prospecting are of great significance to promote the exploration of the nickel deposits related to ultramafic rock bodies in the periphery of Qaidam Basin.

Key words： nickel minerals metallogenic characteristics prospecting potential the periphery of Qaidam Basin
