摘要
地质异常作为找矿重要的间接证据,反映了地质异常体与周围环境在物质、结构等方面的差异性。伴随着信息技术、空间分析技术的发展,地质异常可以通过对遥感、地球物理、地球化学等数据资料进行处理分析获得,并在成矿预测、资源评价等方面有着重要的实际应用。通过对地质异常历史及发展过程的研究,总结和分析了地质异常提取及分析解释的理论基础和常用方法,揭示了地质异常信息在成矿预测、资源评价等方面的重大意义。
Geologic anomaly,reflecting the differences between anomalous body and surrounding geologic environments,can provide significant circumstantial evidences for prospecting.With development of information technology and spatial analysis technology,geologic anomaly is usually abstracted by machine processing of remotely sensed data,geophysical data and geochemistry data.It is proven by summarizing and analyzing methods of geologic abnormal extraction that geologic anomaly has significant application in metallogenic prediction and resources assessment.
