摘要
赛马镇风洞是我国东北规模较大的岩溶洞穴,洞长在2000m以上,已探测长度1265m.风洞具有纵坡降较小、支洞繁多、形态奇异及国内罕见的溶蚀景观“天锅”等特征.岩性、构造、水文地质特征等是控制洞穴发育的基本条件.风洞的发育约始于中更新世40万年前.
The wind cave in Saima Town, Fengcheng City, Liaoning Province is one of the longest karst caves in Northeast China, with a proved length of 1256 m. The cave is characterized by gentle slope, numerous offsets and diverse morphologies, especially its rarely seen solution landscape of “heaven pot” . Lithology, structure and hydrology are the essential conditions for the forming and developing of the cave. Its forming time was around middle Pleistocene of 0.4 Ma.
