| 中文摘要: |
| 针对矿产勘查深度逐渐加大、勘查区逐渐向工作程度相对较低、情况更加复杂的浅覆盖区、山区转移,常规、单一的物探方法在勘探深度及精度等方面都无法满足勘查的需要。文章提出可控源音频大地电磁测深法(CSAMT)与重力测量的技术组合,并将其运用于新疆和田县火烧云铅锌矿勘查实践中。CSAMT测深和重力测量能较好地反映铅锌矿体赋存空间及其顶底板围岩的埋深,铅锌矿体显示低阻高重力异常,中高阻异常围绕低阻高重异常周边分布,依据钻探工程对隐伏矿体进行控制,对应CSAMT测深剖面电阻率等值线区间,大致推断了控矿地质体的厚度和产状,建立了矿床地球物理找矿标志,为矿床勘探及资源量扩大提供了重要的地球物理依据。 |

| In the view of the gradual increase in the depth of mineral exploration, the relatively low degree of exploration and the more complex situation in the exploration area, the conventional and single geophysical methods can not meet the needs of exploration in terms of exploration depth and accuracy. A technology combination of controlled source audio frequency magnetotelluric sounding (CSAMT) and gravity measurement is put forward in this paper.It was applied to the exploration practice of the Huoshaoyun Pb-Zn deposit in Hetian County, Xinjiang. CSAMT and gravity measurement can reflect the depth of the Pb Zn orebodies’storage space and its depth of the surrounding rocks.Orebodies show low resistivity and high gravity anomaly which were surrounded by milder-high resistivity anomaly, According to drilling engineering controlling for concealed orebodies, corresponding CSAMT resistivity isoline,the ore controlling geological bodies’ thickness and occurrence was roughly inferred.Geophysical prospecting marks an important geophysical basis for mineral exploration and increasing mineralresources. |
