| 摘 要： | 神灵寨国家地质公园位于河南省洛宁县南部,园内地质遗产丰富.石瀑产于花岗岩中,同时也是很好的地质遗迹.石瀑所在的花岗岩为中生代花山复式岩体中蒿坪岩体的第二单元.岩石类型为巨斑状角闪黑云二长花岗岩,锆石SHRIMP年龄为131 Ma,时代归属为早白垩世,具备岩墙扩张及气球膨胀模式的双重就位机制.该区石瀑是由岩石球状风化、水流的侵蚀和冲蚀共同作用在花岗质岩石上形成的. |

| Abstract: | Many beautiful landscapes as the waterfall-shaped granite stone for geological heritages have been found in Shenlingzhai National Geopark in Luoning County, Henan Province. The waterfall- shaped stone is regarded as not only as geological record ,but also a real amazing landscape with the integration of the mountain majesty and the water gentleness. These landscapes occurred in the second granite unit of Haoping rock in Mesozoic Huashan complex granite body. The rock type is the megacryst-bearing amphibole biotitic adamellite,The granites have the early-Cretaceous ages of 131 Ma dated by the zircon SHRIMP method, and with the two coexisted emplacement mechanisms of dike-extension and balloon-expansion. The waterfall-shaped stone is usually considered to be formed under physical weathering, spherical weathering or/and water erosion. |
