对东南地洼区某铀矿田的成矿构造与成矿规律所作的初步研究,表明是一个由“花岗岩型”和“碳硅泥岩型”等铀矿床,组成的地洼型多因复成铀矿田。矿床的围岩时代、岩性特点和矿化特征都不相同,但具有统一的成矿机制,成矿时代一致,成矿大地构造背景相同;控矿构造相当及成矿作用相似诸方面。它是中国东部地洼区(尤其是东南地洼区)的一种重要铀矿化类型,具有较大的找矿远景。
A preliminary study on the metallogenetic structure and metallogenic regularity of a uranium orefield in the southeastern depression has shown that it is a multidimensional uranium deposit composed of “granite” and “carbon-silicon mudstone” Uranium ore field. The ore body has different surrounding rock age, lithology characteristics and mineralization features, but has a uniform metallogenic mechanism with the same metallogenic age and the same tectonic setting of the metallogenic earth; similar ore-controlling structures and similar mineralization. It is an important type of uranium mineralization in the depression area of eastern China, especially in the southeastern depression area, and has a great prospect of prospecting.
