| 摘 要： | 在安徽省北部的五河—凤阳地区和蒙城宿县地区研究了地球气组分与花岗岩体的空间分布关系 ,从中发现 ,地球气中La、Ce、Na、K等元素与花岗岩体存在着很好的对应关系 ,并据此可圈定隐伏的花岗岩体的分布范围。这些研究成果 ,将有助于对地球气异常的解释推断 ,同时为覆盖区深穿透地球化学填图提供理论和方法准备。

| Abstract: | A regional survey of nanoscale metals in earth gas (NAMEG) was carried out in the Wuhe Fengyang and Mengcheng areas of northeastern Anhui. The NAMEG are based on the premise that gases generated from the earth's interior cannot only transport the elements from ore deposits, but also transport the elements from the bedrocks. Samples were collected at approximately one site per 25 km 2. Au, Ag, Na, K, La, Ce, etc. were analyzed by Instrument Neutron Activation Analysis (INAA). La, Na, K, Ce anomalies were delineated over and around the concealed granite. |
