| 中文摘要: |
| 楸树湾铜钼矿区是东秦岭铜钼矿带上重要的组成部分,但找矿工作一直未取得明显突破,因此,利用不同方法技术找矿显得尤为重要。通过重力、磁法测量相结合的手段,对其综合剖面分析,指出矿区含矿岩层的产出状态；并结合实测剖面及钻孔验证,在楸树湾矿区确立了钼矿的重磁找矿特征,为下一步找矿提供了物探技术支持。结合矿区的岩性特征可知,重力高异常、磁性相对低异常是寻找钼矿的主要方向；根据矿区钼矿的这一物性特征,可有效寻找目标矿体。 |
| 英文摘要: |
| Qiushuwan copper-molybdenum deposit is important component of eastern Qinling copper-molybdenum belt, but no significant exploration breakthrough in the past. Thus it is particularly important for applying different prospecting methods. By applying combinated gravity and magnetic survey, and on the basis of integrated analysis of the composite anomaly profiles, the attitude of ore-bearing rock body was determined. The prospecting criteria was set up by comparing with field mapped sections and in combination with test drilling work, which provide geophysical information support for the further prospecting direction. Base on the lithological characteritics in Qiushuwan area, the area with high gravity anomaly and low magnetical anomaly is the main direction for finding ore body. |
