Abstract:

Beijing Shihuadong Cave Geopark has a typical low hill erosion terrain, which a long term of erosion and surface water cutting formed a characteristic karst terrain.Beijing Shihuadong cave ranks top in levels in China with all kinds of cave stalactites, and precipitating stone flowers through fine penetrating water, and precipitating stone shields through fissure penetrating water which are most in quantity and biggest in volumes. The stone shoots have a clear overlapping. Fancy in stone flags formed by currents, beautiful in stone moon precipitated by pool water, clear in the Holocene stone shoots micro-bedding. This paper discusses the genesis of the karst cave and studies its sedimentary type.

Key words: karst terrain, geological genesis, scientific development value, Beijing

摘要：

北京石花洞地质公园区内地貌类型属典型的中低山构造剥蚀地貌，在碳酸盐岩沉积分布区经长期风化剥蚀和地表水的切割溶蚀，形成了较典型的岩溶地貌形态。在全国范围内，北京石花洞的层数最多，洞穴钟乳石种类齐全，毛细渗透水沉积的石花美丽，裂隙渗透水沉积的石盾最多、体积最大，滴水沉积的石笋叠置关系最明显，流水沉积的石旗发育奇特，池水沉积的月奶石发育最好，全新世石笋微层理发育最清晰。本文主要讨论石花洞岩溶景观成因，是本小组对石花洞进行的一次大体沉积类型研究。
