在大量岩石样品分析数据和研究成果的基础上,系统分析了新疆北部地区不同时代、不同岩性和不同大地构造单元岩石生热率的分布特征,讨论了岩石生热率与大地构造单元地质特征之间的关系.根据岩石中 K、 Th 、 U 的含量和地壳各结构层的岩石组成,计算了地壳各壳层放射性生热元素的含量,系统研究了新疆北部地区岩石与各时代地层的平均生热率及其变化.岩石生热率分布在一定程度上反映了区域基底生热元素的丰度和岩浆活动的强度.对不同体系生热元素的时空分布与地球化学特征进行了探讨
On the basis of a large number of rock sample analysis data and research results, the distribution characteristics of rock heat production rate in different age, lithology and different tectonic units in northern Xinjiang are systematically analyzed. The relationship between rock heat production rate and the geological characteristics of tectonic units The relationship between. According to the contents of K, Th and U in the rock and the rock composition of crustal layers, the contents of radioactive heat elements in crusts were calculated. The average heat rate of rock in the northern part of Xinjiang and strata of each age and its Variety. The distribution of rock heat rate reflects to some extent the abundance of the basement heat-generating elements and the magma activity. The spatio-temporal distribution and geochemical characteristics of heat-generating elements in different systems were discussed
