遥感技术在金矿勘查中的应用进展

遥感技术在地质领域的应用已不可忽视。遥感图象与区域地质资料,生物地球化学资料进行综合分析、预测区域成矿远景已取得了很大进展,有很多成功的实例。文章概述了国内外遥感技术在金矿勘探中的应用,较为系统地介绍传感器性质、地物波谱特征和图像处理技术,重点叙述岩矿遥感方法和生物地球化学遥感方法探测金矿的原理和探矿方法,并给出了实例。     

Analysis of impact of outfalls on surrounding soil and groundwater environment

With certain outfalls in Baoding as an example and in combination with test results of soil and water samples taken from both sides of such outfalls, the organic contamination compounds influence on the surrounding soil and groundwater environment was analysed, the distribution features of the main organic contamination in soil and groundwater in different depth were discussed, and the vertical and longitudinal migration rule of all kinds of main organic contamination compounds in soil and groundwater in the sewage irrigation area was studied.     

八卦庙大型金矿床含矿岩石中斑点成因及其与成矿的关系

主要从成矿地质背景,含矿层特征和多期成矿等方面阐述了八卦庙金矿岩石中斑点的物质组成及其特征,指出秦岭泥盆纪含矿岩石中斑点状构造为矿流体多期作用的结果且与金矿化关系密切,可作为金矿化的重要标志之一。
