摘要
Thermoluminescences of sediments have been used in exploring oil and gas both on land and on marine, which has achieved great success. Owning to similarity between oil/gas and gas hydrate in origin and mechanism of migration, thermoluminescences could be used in exploration and exploitation of gas hydrate. 147 samples of sediments were collected from the Qiangtang Basin, Qinghai-Tibetan Plateau for thermoluminescence survey. The results of thermoluminescence show that it is characterized by logarithm normal distribution and distinct abnormity. By integrating scientists’ achievement and our survey results, it is concluded that the above thermoluminescence abnormities should be a high value abnormity of hydrate mineral resources.
