南岭是中国重要的金属成矿区,铀是其中一种。南岭铀矿床的成因问题,不少人做过研究工作,基本上都认为是热液矿床,但对热液来源是岩桨残留上升的还是大气降水下降升温的,持有不同观点。笔者根据自己掌握的调查资料,提出填充改造型铀矿床的看法。填充改造型铀矿床,就是富铀地质体经风化剥蚀,铀被大气降水搬运到岩层构造孔隙处还原、聚集,填充,有时还受到地质作用升温、增压的改造而形成的铀矿床。
Nanling is an important metallogenic area in China and uranium is one of them. The cause of the Nanling uranium deposit, many people have done research, are basically considered hydrothermal deposits, but the source of hydrothermal rock residue is rising or precipitation drop in temperature, hold different viewpoints. According to the author’s own investigation, the author proposes to populate the uranium deposit. Filling the remodeled uranium deposits is the uranium deposit formed by the weathering and denudation of uranium-rich geological bodies, the removal of uranium by atmospheric precipitation and the reduction, accumulation and filling of pores in the rock formations, and sometimes by the geological effects of warming and pressurization.
