摘要
粤北浰源岩体位于大东山—贵东之东西向岩浆岩带东端,产出的铀矿化类型以花岗岩型为主。分析了浰源岩体产出的区域地质背景、岩石地球化学特征、热液蚀变特征及铀矿化等特征,结合类比同一岩浆岩带上围岩体中的古坑矿床的控矿因素、围岩蚀变、矿物共生组合、矿石类型等,探讨浰源岩体铀的成矿规律,认为浰源岩体属华南地区产铀花岗岩体,具有寻找较大型花岗岩型铀资源的潜力,指出了目前勘探工作的不足,提出了下一步铀矿勘查工作的重点和建议。
The Liyuan rock body in nothern Guangdong Province is located at the eastern end of the east-west trending magma belt in Dadongshan-Guidong,and the type of uranium mineralization produced is mainly granite.The metallogeny of uranium deposit is briefly analyzed from the regional geological background,rock geochemical features,hydrothermal alteration characteristics and uranium mineralization characteristics,before combining and comparing the ore-controlling factors,surrounding rock alteration,paragenetic association of minerals and ore type of the Gukeng deposit in Shangwei rock body of the same magma belt.It is believed that the Liyuan rock body falls into uranium-bearing granite body in South China,and has a great potential of producing large uranium of granite-type.The deficiency of the current exploration is pointed out before making suggestions about the focus of future.
