Title: Study on Finding out Uranium Deposit with Geophysical Methods at Zhongdong District Onyuan County Guangdong Province
Abstract: The soil natural thermoluminescence measurement and radon survey were chosed,whose penetrability is stronger,and their applied effects were studied in prospecting uranium deposit at Xiazhuang granite area.The 236 stations were measured respectively with these two methods at Zhongdong district Ongyuan county Guangdong province.The research results shaw that:1.There are good effects which fractured zones were found out with radon survey.2.The soil natural thermoluminescence measurement is one of the cumulative measurement methods.It can obviously respond the projected position of uranium deposit of intersected point type.3.The sensitivity,stability and reappearance of the soil natural thermoluminescence is good,and it was less affected by human activity on the surface.The measured anomalies can reflect the variety of the radioactive field,so amplitude and width of anomalies can basically respond the distribution of uranium ore body.The problems to be solved in the future are:If the rocks above the intersection point type uranium deposits are relatively intact,how much depth can it be found out with soil natural thermoluminescence method? A set of nuclear geophysical prospecting pattern on the different types of uranium deposits in Xiazhuang uranium ore field should be summarized so that they can be used to find out uranium deposits in granite area in the future.
