摘要
本文对小秦岭(陕西境内)高山河群与小河岩体的接触关系性质,从点到面,从微观到宏观进行了扼要的论述,并明确指出二者非侵入接触,而应是沉积不整合接触,在此基础上探讨了小河岩体的时代。
The contact relation between Gaoshanhe group and rock mass in Xiaohe is describedbriefly, from a point to a plane, from microscopic to macroscopic, in Xiao Qinling (whichlocates in Shaanxi province). It is pointed that the relation is not intrusive contact betweenthem, but is depositional unconformity. On the bsis of the above, the geological age of r0ckmass in Xiaohe is studied in this paper.
