摘要
我国南方红土型金矿属改造红土型金矿，进一步可分为古层间构造带淋积型、岩体接触带淋积型及岩溶洼地堆积型三个亚类，以及蛇屋山式、龙形寨式、大坊式、北衙式、百色式、老万场式及镇圩式等七个矿床式。各类矿床在产出的构造部位、成矿作用、含金红色风化壳剖面、金矿源体及金的产出特征上有其自身的特征。同时指出了我国南方红土型金矿的时代、地理及地貌分布特征。
The laterite gold deposits in south China,which belong to reformed laterite deposits,can be divided into three subclasses,i.e.leached deposit in old interstrarta structure,leached sedimentary deposit in contact zone of rock bodies,accumulated deposit in karst depression,three subclasse of laterite deposits are further classified into seven types including Shewuyshan、Longxingzhai、Dafang、Beiya、Beise、Laowanchang and Zhenxu etc.Different types of deposits have thier own features including structural location of occurrences、mineralization、gold-bearing laterite profile of weathered crust、gold-forming resources and feature of gold occurrences.The metallogenic epoch、geographic and geomorphologic distribution features of laterite deposits in south China are also discussed.
