The Applied Technique Regarding Data of Gold Placer Mineral Anomalies in the Large Scale Prospecting Assessments of Gold Deposits

The method of gold placer mineral includes significant prospecting information in the prospecting assessments of gold deposits. By influencing of work scale, gold placer mineral anomalies in 1∶50000 and 1∶200000 regional geological survey are not useful value in the large scale prospecting assessments of gold deposits. Authors put forward the catchpits network dividing method of gold placer mineral anomalies, basing on features and forming mechanism of the anomanlies. By using the method , the gold placer mineral anomalies of large area and gold source indistincition are divided into new catchpits anomalies of the smallest range and gold source distinction. Thus,the data of gold placer mineral anomalies can be applied efficienty and secondly in the prospecting assessments.The methotl is useful and effective in prospecting assessment of gold deposits in east Hunchun district of Jilin Province.
