新疆北部福海地区大地构造特征

TECTONICS CHARACTERISTICS IN FUHAI AREA IN NORTHERN XINJIANG. XJPG

简要介绍了新疆北部福海地区大地构造背景、磁性基底特征、构造单元划分及特点,探讨了大地构造演化史.认为该区古生代北为西伯利亚板块,南为哈萨克斯坦板块,两大板块的缝合线为额尔齐斯深大断褶带.北部属阿尔泰古陆缘构造岩浆活动带,南部属北准噶尔弧盆带,两大板块缝合于晚石炭世.

This paper briefly described tectonics setting, magnetic basement characteristics and division and characteristics of structural element in Fuhai area of northern Xinjiang, and tectonic evolution history was discussed. It is suggested that in the Paleozoic it consists of the Siberia plate in the north and Kazakhstan plate in the south, both of which sutured with the Erqis. The north is Altay ancient continental margin magma active belt, while the south is north Junggar arc-basin belt, both of which were sutured in Late Carboniferous.
