夜晚的珍罗兰洞穴群
Regarded as Australia's most outstanding cave system, with pure underground rivers and amazing limestone crystal formations, Jenolan Caves, located 30 km south-east of Oberon, is one of the finest and oldest cave systems in the world. The Cathedral Chamber of the Lucas Cave is reputed to have the finest acoustics of any performance space in the world. Jenolan is known as an ‘impounded' Karst, as the limestone receives water from the surrounding insoluble rocks. Caves and karst features are produced because limestone is soluble in water containing dissolved carbon dioxide. Rain absorbs CO2 from the atmosphere thus providing the catalyst for the creation of this remarkable place.
珍罗兰洞穴群位于奥伯伦东南30公里处，拥有纯净的地下河流和绝美的石灰石晶岩，是世界上最优美，最古老的洞穴系统之一，也是澳大利亚最壮观的洞穴群。 其中，卢卡斯山洞中的天主教堂大厅的音响效果非常出色，可媲美世上最好的表演厅。珍罗兰山洞群属于“溶蚀洼地型”喀斯特地貌，其形成原理是：石灰岩容易被富含二氧化碳的水溶解，在雨水吸收了大气中的二氧化碳并由非溶性岩石流入时，就会将石灰岩溶解，渐渐形成壮观的地下洞穴系统。
