| 摘 要： | 朋友砂金矿床位于秘鲁南部亚马逊盆地中,具有典型的热带雨林气候和独特的水文地质特征.第四系松散堆积层发育完全,厚度大.圣母河砂金矿的富集有明显规律性,其与水文地质条件及物质来源相关,这种成矿规律性可用一模型来描述,该模型适用于具有金矿成矿物质来源的热带河流冲积型砂金矿床.合理的找矿方法是热带雨林地区砂金矿床定位评价的关键.

| Abstract: | Friend gold placer is located in Amazon basin of the south of Peru. It is characterized by the classic feature of selva and unique hydrology. Quaternary overburden is completely developed with thick layer. The ore accumulation of Madonna river placer shows clear regularities which is associated with the hydrogeological condition and matter source. This regularity can be described by a model that is fit for tropic river alluvial gold placer with gold ore matter source. Reasonable prospecting method is a key to localizing and evaluating gold placer in selva. |
