| 摘 要： | 在新疆哈密和甘肃安西县交界地带的金窝子210隐伏金矿上方，运用泡塑捕集器和液态捕集液进行大比例尺地气测量，深入研究地气测量方法在野外的应用。试验结果显示，隐伏金矿体上方出现了较为明显的Au地球化学异常，并伴随Cu、Pb、Fe等成矿伴生元素的地球化学异常，异常与覆盖层厚度、矿体产状、构造等因素相关。地气法捕集的微量物质的稀土配分模式与210金矿矿石样品的稀土配分模式相似，证明了捕集的微量物质来源于深层隐伏矿体，体现了地球化学深穿透方法在戈壁地区隐伏矿产勘查中具有良好的应用前景。 |

| Abstract: | Using the foam trap and liquid trap,the authors carried out large-scale geogas survey in the Jinwozi V210 concealed gold deposit located in the boundary between Hami of Xinjiang and Anxi of Gansu,and studied the field application of the geogas survey method.The results indicate that Au geochemical anomalies are quite clear over the ore deposit and are associated with some other anomalies such as Cu,Pb and Fe.The anomalies found at the surface are related to the depth and attitude of the ore body and the structures.The REE patterns of the trace elements collected in the process of this survey are similar to patterns of the trace elements collected from the ore body,suggesting that the trace elements over the gold deposit were derived from the buried ore body.This study shows that the deep-penetrating geochemical method for concealed ore deposit prospecting in gobi area has promising future. |
