Geological Survey of Jinshan Gully Caldera is located in the northeastern margin of the East Junggar Basin. On the earth structure, the Jinshan Gully caldera is located in the western part of the Kalamaili-Mechin-Ula uplift, the Keramemali anticline and the East Junggar Basin, That is, distributed in the north-east and north-west to the conjugate of the two basement faults. Volcanic activity in the area is intense and frequent. Only Carboniferous Early Early Carboniferous Tuneo-Eocene cycles, late Naumeier eruption cycles and Middle Carboniferous eruption cycles. In the euphonistic, the most intense eruption is nanmuir, the activity takes a long time and distributes
