摘要
通过Map GIS平台对地球化学测量单元素异常与遥感解译环形构造进行相关性分析,观察两者空间位置的相互关系,划分两者套合类型.依据遥感解译形成的测区构造格架特征,认识单元素异常、组合元素异常在构造格架中的分布特征和与环形构造的空间配置特点,建立两者套合关系,判断两者的地质作用意义.利用这种套合关系开展有针对性的矿产地质调查工作,提高化探异常验证和找矿工作的成效.
With Map GIS platform, the correlation of element anomaly by geochemical survey and circular structures interpreted by remote sensing is analyzed. Based on the interrelationships of spatial positions of the two factors, the coupling types are classified. According to the remote sensing interpretation of the structural framework in the surveying area, the distribution characteristics of the element anomaly in the structural framework are recognized. With the establishment of the coupling relationship between the geochemical anomalies and circular structures, the geological significance of the two factors is studied. This coupling relationship can be used in geological investigation for mineral resources to improve geochemical anomaly verification and mineral exploration.
