| 摘 要： | 2011年,勘查单位对西藏桑日县某铬铁矿采用1:5000重磁物探进行勘查。根据工作区岩矿的物理特性建立了铬铁矿的地球物理模型与找矿标志,在后期处理过程中采用各向异性标准差、迭代切割场、曲化平等方法技术对重磁异常进行精细处理,推断了超基性岩体的范围,并通过对重磁异常的分析指出了成矿的前景靶区。

| Abstract: | In 2011, a prospection company applied 1：5000 gravity and magnetic comprehensive geophysical prospection for the exploration of chromite mineral in Sangri country in Tibet. Geophysical model and ore-prospecting criteria of chromite were set up based on physical characteristics of rock ore in the workspace. In the process of post-processing, anisotropie standard deviation, iterative cutting field and the curved equal method were adopted in precise processing for gravity and magnetic anomaly. The scope of the ultrabasic rock mass was infered, and metallogenic prospecting target areas were point- ed out through the analysis of gravity and magnetic anomalies. |
