| 中文摘要: |
| 甘肃省南部大水金矿外围开展1∶1万土壤地球化学测量,采集样品7109件,共分析11种元素,获取地球化学数据。以土壤地球化学测量图件为基础,结合异常区内地质背景、各元素及异常分布、分散富集特征圈定综合异常,并将3处有找矿前景的综合异常予以解释。该区元素之间异常套合程度较好,即主成矿元素Au与As、Hg、Sb、W等伴生指示元素之间的相关性较好,异常又与岩浆作用密切相关,从而佐证了大水金矿地区矿场的中低温岩浆热液成因。 |
| 英文摘要: |
| Depending on the mineral prospecting project in the ore-concentrating zone, southern Gansu, carry out 1∶10000 soil geochemical measurement on the periphery of Dashui gold deposit, collect 7109 samples, analyze 11 elements in total, obtain geochemical data, make synthetic arrangement and statistical analysis of those data, obtained geochemical data. On basis of soil geochemical measurements we have made in this area, combining the geological background, each element and their anomaly distribution and dispersed richness, we circled synthetic anomaly and also gave explanation to 3 anomalies of ore prospect. The anomaly combing level among elements is fairly good, naming that the relevance between major ore element Au and associated indicating elements such as As, Hg, Sb, W is fairly good and that anomaly is also closely related to magmatism, thus proving the medium to low temperature magmatic hot fluid genesis of Dashui gold deposit. |
