| 摘 要： | 印支一燕山期，在鄂东南地区形成了三个逆冲滑覆构造带，分别与北区、中区、南区三个燕山期花岗岩类超单元组合相对应。其中，北区由３个超单元、１３个单元组成．中区由６个超单元、２３个单元组成，南区由２个超单元、５个单元组成。不同的谱系单位在控岩类型、岩浆演化和微量元素诸方面具明显差异，并有各自的成矿特点。

| Abstract: | According to the new study, three thrust gliding nappes formed during indo-Sinian Yanshanian period in southeastern Hubei, which ave corresponding to three Yanshanian grantic ultraunit suites: respectively the North, the Middle and the South regions. Among them, the North ultraunit suite is constituted by 3 ultraunits which have 13 units, the Middle ultraunit is involved in 6 ultraunits which have 23 units and the South ultraunit suite is com posed of 2 ultraunits which have 5 units. Each systematics exists obviously difference in rock controlling type,evolution of the magma and trace elements,and leads to different mineraliza tion character. |
