Abstract:Based on the elemental analysis results of rock samples collected by the 1:200 000 stream sediment geochemical survey in northern Daxinganling Mountains, the paper counts the contents of 39 elements in the Mesozoic granitoids, analyzes the geochemical characteristics of elements, and presents the abundance values of elements in the Mesozoic granitoids of northern Daxinganling Mountains. It is concluded that the Mesozoic granitoids have the characteristics of potassium-rich acid granites and aluminium-rich acid-intermediate granites, which are closely related to the Mesozoic tectonic movement and magmatic activity.
