岩浆岩侵入体由于它的脆性和成块状产出的特点,过去一般认为它不能和沉积岩一样褶皱。有些国外资料只强调了固结的岩浆侵入岩受到构造作用,可以用岩组分析方法来确定它遭受的变形,但限于研究这些岩体的裂隙构造特性。笔者根据山东地质六队李士先等同志提供的线索,在招远玲珑金矿九曲矿段276米标高硐口的玲珑花岗岩体中,通过宏观考察和岩组分析,确定了一个小型的右型斜列式褶皱(见照片1,图1)。
Magmatic intrusions were generally considered to be unable to fold like sedimentary rocks due to their brittleness and their lumpiness. Some foreign sources only emphasize that tectonic magma intrusions are tectonic in nature. Rock analysis can be used to determine the deformation they are subjected to, but the fracture characteristics of these rocks are limited. According to the clues provided by Li Shixian and other comrades in Shandong Geological Sixth Team, the author determined the small right-type inclined plane through the macroscopic investigation and the analysis of the rock group in the exquisite granite body with 276 meters elevation hole in the Jiuqu Mine section of Zhaoyuan Linglong Gold Mine. Column fold (see photo 1, Figure 1).
