为了探讨各种算法在地球化学元素异常圈定的效果,本文选取传统方法、累频法,概率格纸法以及非线性统计分析方法(C-A)对谢通门地区的地球化学元素数据进行异常提取研究。结果发现85%累频和概率格纸法的没有完全展现出异常区域,C-A能较好的体现出异常区域,传统计方法虽然能较好的体现出异常区域,但确定的区域过大给勘探带来困难。从而在实际勘探中需结合具体地质背景,合理选取方法。
In order to explore the effect of various algorithms on the delineation of geochemical anomalies, this paper selects the traditional method, the frequency method, the probability grid method and the non-linear statistical analysis method (CA) to study the abnormal extraction of geochemical element data . The results showed that 85% of the cumulative frequency and probability grid paper method did not fully show the abnormal area, CA can better reflect the abnormal area, although the traditional method can better reflect the abnormal area, but the determined area is too large for exploration Bring difficulties Therefore, the actual exploration needs to be combined with the specific geological background, a reasonable choice of methods.
