许多国家多年来的铀矿普查实践表明:绝大多数有经济价值的铀矿床都与所谓“高铀区”有关,不是产于其中,就是产于它的边缘。对世界主要工业类型铀矿床来说,这是一个普遍的规律。近几年来,对我国产铀花岗岩体的研究表明,一般含铀丰度在10—30 ppm之间,比正常含量高2.5—7倍之多。虽然花岗岩型铀矿床是我国的重要铀矿床工业类型,但是,到目前还没有从区域上在这方面做系统的工作。由于区域地质研究的需要,提出利用航空放射性测量资料对这一类型铀矿床区域放射场的特征进行研究。由于我国航空γ能谱测量所取得的成果还不能满足要求,因此,只能利用已有的航空γ总量测量资料来探索这一研究课题,为成矿地质规律和成矿理论研究提供一个区域放射性背景资料。
The uranium census practices conducted by many countries over the years show that the vast majority of uranium deposits of economic value are related to the “high uranium zone” of the so-called “high uranium zone” and are neither produced nor produced on the brink of it. This is a common rule for the world’s major industrial uranium deposits. In recent years, the research on the uranium granite in our country shows that the average abundance of uranium is between 10-30 ppm, which is 2.5-7 times higher than the normal content. Although granite-type uranium deposits are an important industrial type of uranium deposits in our country, so far we have not done systematic work in this area from the area. Due to the need of regional geology research, it is proposed to study the characteristics of radiation field in this type of uranium deposit by using aeronautical radioactive survey data. As China’s aviation γ-ray spectrum measurement results can not meet the requirements, therefore, can only use the existing total amount of aviation γ survey data to explore this research topic for the study of metallogenic geology and metallogenic theory to provide a region Radioactive background information.
