广东银矿成矿系列及区域成矿谱系

Metallogenic Series and Regional Mineralizing Pedigree of Silver Deposits in Guangdong Province

本文将广东省银矿床厘定为5个矿床成矿系列、6个矿床成矿亚系列,即云开地区与加里东运动有关的银矿床成矿系列、华南与晚古生代沉积作用有关的银矿床成矿系列(包括华南中泥盆世至早石炭世与海相碳酸盐岩有关的银矿床成矿亚系列和粤东北中晚石炭世与火山-沉积作用有关的银矿床成矿亚系列),南岭及周边与燕山期构造-岩浆作用有关的银矿床成矿系列、东南沿海与燕山期火山-侵入活动有关的银矿床成矿系列(包括粤东北印支-燕山期与残余海相火山活动有关的银矿床成矿亚系列和粤东与燕山晚期侵入岩有关的银矿床成矿亚系列)和三水-罗定盆地与燕山-喜山期岩浆-流体有关的银矿床成矿系列(包括粤东北印支-燕山期与残余海相火山活动有关的银矿床成矿亚系列和三水盆地与晚白垩世-古近纪构造或火山活动有关的银矿床成矿亚系列)。分别论述了各成矿(亚)系列的基本特征,并根据广东省区域地质构造发展史,建立了银矿区域成矿谱系。

Silver deposits of Guangdong province are divided into five metallogenic series and six metallogenic sub-series： （1） Caledonian movement related silver metallogenic series in Yunkai area; （2） Late Paleozoic sedimentary related silver metallogenic series in South China （including Middle Devonian to Early Carboniferous marine carbonate related silver metallogenic sub-series in South China and Late Carboniferous volcanic - sedimen- tary related silver metallogenic sub-series in Northeastern Guangdong province）; （3） Yanshanian tectonic-mag- matic related silver metallogenic series in Nanling range and surrounding areas; （4） Yanshanian magmatic related silver metallogenic series in Southeast Coast （including Indosinian-Yanshanian residual marine volcanic activity related silver metallogenic sub-series in Northeastern Guangdong province and Yanshanian magmatic related sil- ver metallogenic sub-series in Eastern Guangdong province）; （5） Yanshanian-Himalayan magmatic-fluid related silver metallogenic series in Sanshui-Luoding basin （including Yanshanian shallow - super shallow acidic intrusive rocks related silver metallogenic sub-series in Sanshui basin and Late Cretaceous - Paleogene tectonic or volcanic activity related silver metallogenic sub-series in Luoding basin）. The features of every silver metallogenic series （or sub-series） are discussed in detail, and the regional silver metaUogenic pedigree is established based on regional geological evolution in Guangdong province.
