摘　　要：广东与燕山期岩浆作用有关的矿产资源,共厘定了4个矿床成矿系列,12个矿床成矿亚系列。其区域分带特征,与古太平洋构造域的构造-岩浆活动有关。与燕山期壳源岩浆作用有关的矿产,在粤北地区主要受近EW向构造的局部张裂部位及NE—NNE向构造控制,其他地区主要受NE向构造控制,总体上呈面型分布,由粤北向南,可分出W、Fe-Sn-W和Sn-Pb-Zn三个带;与壳幔源岩浆作用有关的矿产,主要受NNE、NE向沟通地幔的深大断裂控制,在粤东地区呈面型分布,其他地区呈线型分布。在成矿时空演化方面,除云开地区是一个构造-岩浆-成矿作用长期活动的区域外,总体上从粤北向南、东南方向,矿化类型逐渐变化,成矿时代也逐渐变新。这种区域分带,通过不同地域出现的形成于晚侏罗世、早白垩世和晚白垩世的矿床及花岗岩体的多寡体现出来,是古太平洋构造域构造-岩浆活动以及古近纪以来壳上剥蚀的结果。The mineral resources related to Yanshanian magmatism in Guangdong province have been classified to be 4 ore-forming series and 12 ore-forming sub-series.Its regional zonation is related to the structural-magmatic activities in the tectonic domain of the ancient Pacific Ocean.The mineral resources related to Yanshanian crustal magmatism in North Guangdong are mainly controlled by the local tensional part of the near EW structure and NE-NNE deep structure.Those in the other areas are mainly controlled by the NE deep structure,and generally distributed in a plane type.From the North to the South Guangdong,there can be divided into three ore zones of W,Fe-Sn-W and Sn-Pb-Zn deposits.The mineral resources related to crustal mantle magmatism are mainly controlled by the NNE and NE structural fault which touches the mantle.The mineral resources at the East are generally distributed in a plane type,and those at the other areas are distributed in a linear type.In terms of the time-space evolution of mineralization,in addition to Yunkai area,which is a long-term tectonic-magmatic-metallogenic activity area,the ore-forming types gradually change from the North to the South and Southeast Guangdong,and the metallogenic epoch gradually changes to be newer.The regional metallogenic zonation is the result of tectonic-magmatic activities in the Paleopacific tectonic domain and crustal weathering denudation since Paleogene,as it is reflected by the number of deposits and granite bodies formed in the Late Jurassic,Early and late Cretaceous.
