| 摘 要： | 近年来,在崂山A型花岗岩中发现了一些大型气泡状晶洞,最大的直径可达3.1m,远超过以往报道过的花岗岩晶洞。这一发现,不仅对研究崂山花岗岩形成的原生环境有重要意义,而且也揭示了崂山花岗岩"天然石臼"的真正成因。同时,从洞穴学角度也肯定了一种新的洞穴类型的存在。花岗岩大型气泡状晶洞是珍稀的地质遗迹,具有较高的观赏和旅游价值,应加以保护。

| Abstract: | Recently, some large bubble-like rniarolitic caves in an A-type granite of the Laoshan Moun-tain have been discovered. The largest cave is up to 3.1 m in diameter, far exceeding the granitic mi-arolitic caves previously reported. The discovery is helpful to the study of the original environment of the Laoshan granite and to the genetic interpretation of the microqandform of ＂natural-mortar＂ there. The existence of a new genetic type-＂bubble-like rniarolitic caves＂ in speleology is also confirmed by this discovery. Such large bubble-like rniarolitic caves are rarely observed in geological records. It has ornamental, scientific and tourism value. |
