青海省都兰县瑙木浑沟口金矿区位于昆中构造带北侧，区内断裂构造十分发育，主要为NW向断裂，与区域构造方向基本一致。区内含矿蚀变带与 NW向深大断裂成矿关系密切，NW向断裂为区内的主要导、控矿构造，其次级构造或构造膨胀部位及构造拐弯处，均为找矿的有利地段，推测为容矿场所。该区华力西期岩浆活动强烈，剧烈的构造运动为金元素的活化、迁移、富集、沉淀提供了通道和成矿空间。研究认为氧化标志、蚀变标志及构造标志是该区的主要找矿标志。

Naomuhun Goukou gold deposit in Dulan county of Qinghai Province locates in north part of cen-tral Kunlun tectonic zone .Faults structures are mainly composed of structures with the trend of NW de-veloped well in this area .Alteration zone is closely associated with NW trend fault .Faults with the trend of NW are main ore controlling faults .Its secondary faults ,structral expansion areas and strucutral bend areas are favourable areas for ore prospecting ,and is considered to be a place of hosting ores .The mag-matic activity is concentrated in Hereynian period .Strong movements provided ore forming spaces for ac-tivization , transportation ,concentration and settlement of gold elements . Oxidation marks , alteration marks and structral marks are main prospecting marks .
