努和廷式铀矿床地质特征及其油气水与铀成矿作用探讨

DISCUSSION ON GEOLOGICAL CHARACTERISTICS OFNUHETING TYPE URANIUM DEPOSIT AND THE RELATION BETWEEN OIL AND GAS-BEARING WATER AND URANIUM METALLOGENESIS

本文应用有机地球化学原理探索油气水与铀矿化的关系，并总结了＂努和廷式＂铀矿床的地质特征和成矿机理。＂努和延式＂铀矿床产于中新生代陆相盆地油气田的顶部或边部，矿床规模巨大。铀矿床形成与油气田中油气水渗漏所造成的地球化学环境及物质参与有关。据此提出＂以油找铀＂的找矿思路。

This paper applies organic geochemical principle to investigate the relation between oiland gas-bearing water and uranium mineralization,and sums up geological characteristis andmetallogenetic mechanism of Nuheting type uranium deposit. Nuheting uranium deposit is located at the top and marginal part of oil and gas field in Ceno-Mesozoic continental basin andis of large size.The formation of uranium deposit is related with geochemical environmentand matter participation due to oil and gas-bearing water's percolation. Accordingly,the concept of exploration──'to prospect for uranium by oil'has been proposed.
