摘要/Abstract

摘要：

在金矿找矿和评价工作中，重砂测量方法能提供重要找矿信息。受工作尺度的影响，以往获得的金重砂异常资料(1：50000或1：200000)很难在大比例尺矿产资源评价工作中得到利用。根据已获取的金重砂异常资料的特点和重砂异常形成的机理，本文提出了金重砂异常汇水盆地网系分割法，将原来的规模大、异常源模糊的金重砂异常重新分割，形成规模小、物原清晰的汇水盆地异常，实现了金重砂异常资料的二次开发。该法在吉林珲春东部地区金矿资源评价中得到应用，效果良好。

关键词: 大比例尺矿产资源评价, 汇水盆地网系分割法, 金重砂异常资料

Abstract:

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 cab be applied efticienty and secondly in the prospecting assessments.The method is useful and effective in prospecting assessment of gold deposits in east Hunchun district of Jilin Province．

Key words: Large scale prosecing assessments of mineral resources, The dividing method of the eatchpits network, data of gold placer mineral anomalies
