我国花岗岩分布较广,与花岗岩有关的铀矿床有着重要的意义。对花岗岩地区铀矿床的地质特征和成矿规律,进行了大量的研究工作。但有关控矿机理的论述不多。笔者曾于1974年5月,提出了断块相对隆起区(隆起带)和断块相对陷落区(断陷带),并把后者单独划为成矿带。由于勘探工作的需要,在探索隐伏矿体的预测和定位工作中,需要有进一步的认识作指 Granite is widely distributed in China, and granite-related uranium deposits are of great significance. A great deal of research work has been done on the geological characteristics and metallogenesis of uranium deposits in granite area. However, there are not many expositions about the ore-controlling mechanism. In May 1974, the author proposed the relative uplift zone (uplift zone) and the relative subsidence zone (down-zone zone) of the fault block and classified the latter separately as the metallogenic belt. Due to the need of exploration, further exploration is needed to explore the prediction and positioning of hidden ore bodies
