| 摘 要： | 昆仑山口—两湖地区是青海省主要的金矿生产基地,已查明金资源量约占全省的53%。通过对该地区金矿成矿特征的研究,认为成矿类型为破碎蚀变岩型。结合化探、物探和遥感综合地质信息,提取控矿构造、物化遥预测要素,应用GIS手段,通过综合信息叠加圈出靶区,缩小该区找矿范围。选择大场金矿床作为模型区,与圈定的靶区进行相似度类比,应用地质体积法估算资源量,从估算结果来看,查明资源量约占预测资源量的1/4,说明该区金资源潜力巨大。 |

| Abstract: | The Kunlun Mountain-Lianghu region was a major production base of gold in Qinghai Province,moreover,the proportion of golden resources in the region was approximately 53% of the Province.Through the study of gold metallogenic characteristics of the area,we believe that metallogenic type belongs to the broken alteration rock type.Combining with geochemical,geophysical and remote sensing comprehensive geological information,extracting the ore-controlling structure,and comprehensive prediction factors,and application of GIS,we narrowed the scope of prospecting in the area through the comprehensive information overlapping circle target area.After choosing Dachang gold deposit area as a model,making similarity comparison with delineated the target area,employing the geological volume method to estimate resource,we attained the result that resources made up about a quarter of predicted resources,which illustrated the gold resource potential was tremendous. |
