发育于中寒武统厚层状鲕状灰岩和薄层泥质灰岩中的河北临城崆山白云洞是一个上下三层 ,总长 50 0m、面积 4 2 0 0m2 的小型旅游洞穴。洞内碳酸钙景观极其丰富 ,尤其是石幔、卷曲石、石葡萄。白云洞老洞积石已发生了强烈的风化 ,洞积石已变得疏松 ,易折断和掉块。在老洞积石强烈风化处或在风化洞积石上 ,发育了新的洞积石。在白云洞所在的崆山山脊上保留了三十万年前形成的大型石笋基群和洞穴石葡萄、石瘤和钙板等。根据洞穴中的裂隙网和迷宫洞道、洞穴太湖石、地下湖及地下水补排特征 ,作者认为白云洞是喀斯特地下水对石灰岩泡蚀作用的产物。
Developed in the mid-Cambrian thick-bedded oolitic limestone and thin-bedded argillaceous limestone, the Baiyun Cave in Lingshan, Lincheng, Hebei Province is a small tourist cave with a total length of 500m and a surface area of 400m2. Caverns inside the cave is extremely rich landscape, especially stone mantle, curl, stone grapes. The old cave stone in Baiyun Cave has undergone intense weathering. The cave stones have become loose, easily broken and dropped. In the strong weathering of old burrows or on weathered burrows, new burrows developed. On the ridge of the ridge where the Baiyun Cave is located, large-scale stalagmite groups and cave grapes, stone tumors and calcium plates formed three hundred thousand years ago are preserved. According to the fracture network in the cave and the labyrinth tunnel, the cave Taihu stratum, the underground lake and the groundwater recharge feature, the author thinks that the Baiyun cave is the product of karst groundwater foaming on the limestone.
