××山花岗岩体,呈大岩基产出。出露面积1633平方公里,在区域构造上位于雪峰新华夏系构造带东南段的资新复式向斜内。岩体受南北向及华夏系构造体系的联合控制。北段呈南北向展布;南段作北东30度方向延伸;中段恰为上述两者的结合部位,形成构造软弱地带,为晚期岩浆侵入和构造的发育奠定了基础(图1)。
× × Shan granite body, a large rocky out. Out of an area of 1,633 square kilometers, in the regional structure is located in Xuefeng Xinhuaxia structural southeast section of the new compound syncline. The rock body is jointly controlled by the North-South and Cathaysian structural systems. The northern segment is distributed in the north-south direction. The southern segment extends 30 degrees to the north east. The middle segment is just the combination of the above two parts and forms the structural weak zone, which lays the foundation for the late magmatic intrusion and structural development (Figure 1).
