崂山气泡洞特征及与天然石臼的联系

Characteristics of Bubble-like Caves and Contact of Natural-mortar in the Mount Laoshan

作为中国东部A型花岗岩带的一部分,青岛崂山花岗岩岩体上不仅发育众多开口向上的天然石臼,还存在众多开口侧向的大型气泡洞,利用立体镜分别观察人工作用、风化作用、水动力作用等不同成因岩石的表面微观特征,通过与气泡洞洞壁岩石表面特征对比发现,大型气泡洞洞壁表面无外力作用的痕迹,初步认定这些大型洞穴属于原生气泡洞。崂山花岗岩岩体上天然石臼周围经常伴生众多的小型晶洞,两者之间可能存在某种必然的联系,这种联系可以为研究崂山晶洞花岗岩原生环境提供新的依据。

As a part of A-type granite belt in the eastern China, it not only developed many openings up naturalmortar,there are many openings lateral holes of large bubbles in Laoshan granite rock, respectively using stereoscope were observed the surface of the rock microcosmic characteristics in the different genesis, mainly includes artificial,weathering, hydrodynamic. Compared with the surface characteristics of the bubble caves, the surface of large bubble caves without external force, preliminary concluded that these large bubble caves belong to primary caves.There are a lot of little miarolitic caves around the natural-mortar in Laoshan granite rock, and there may be a necessary connection between them, it can provide a new evidence for the study of Laoshan miarolitic granite primary environment.
