The ε(322Ma) values of two wolframite separates from the greisen massive ore range from 4.24 to 5.93, much higher than values of the ancient continental crust and Precambrian metamorphic rocks.

相比之下，黄玉－石英脉型钨矿石中5件黑钨矿样品的ε(322Ma)值变化范围为-4.16~-8.05，与同时期古大陆壳钕同位素演化线值相似。

In some way, the nature of the geochemical field shows that the deep fluid took part in the energy mineral reservoir formation and mineralization.2、 In zones with the strong tectonic activity and basement faults, the elements combination of petroleum is complex and the material from deep resource can be found in which. The character of elements geochemical and carbon isotope all show that there are deep fluid components in some Energy Minerals. The material source of the water accompanying with petroleum reservoir is complex, and which with multi-sources. The character of elements geochemical shows that the uranium of Dongsheng uran ore comes from the upper crust, the greyish-green gritstone and hoary kaolinised argillaceous siltstone is important for the formation of uranium deposits,and the grey gritstone is great potential to surveying uranium deposits .

基底断裂带和构造活动强的区域，原油中元素组合复杂，并含有深源物质；元素地球化学特征和同位素特征反映部分能源矿产中含有深部流体成分；盆地内油气藏伴生水的物质来源较为复杂，具有多源性；元素地球化学特征显示东胜铀矿的铀源主要来自上地壳，灰白色高岭土化泥质粉砂岩及灰绿色粗砂岩对铀矿的形成具有重要的意义，灰色粗砂岩具有良好的找矿潜力；元素地球化学特征还表明，黑岱沟煤及煤层夹矸中微量元素来源于上地壳。
