翠华山国家地质公园位于西安市南郊，包括三个景区，水湫池、甘湫池、大坪观景台。新的野外调查发现，甘秋池风景区是一处罕见的大型古岩滑坡，具有典型的滑坡地貌特征，崩塌、散落的岩石覆盖在周边古滑坡上，甘秋池是一个拉深延伸的洼地，而不是由崩塌堆积物形成的堰塞湖。水湫池水库大坝为典型的泥砾结构，系泥石流堆积，其形成与山体崩塌无关。从存款层的空间分布和顺序来看，地质公园内的崩塌和散落的岩石都是在滑坡和泥石流发生时形成的。不同地点的崩塌岩大小不同，形态各异，地质公园周围的崩塌存款岩形成的原因不同，形成的时期也不同。这些概念对科学认识地质遗迹及其旅游开发具有重要意义。
Cuihuashan Mountain National Geo-Park is located in the southern suburbs of Xi’an City, and it includes 3 scenic areas,i.e.,the Shuiqiuchi Pool,Ganqiuchi Pool and Daping Sightseeing Platform. In a new field investigation,it was found that Ganqiuchi Pool scenic area is a rarely and huge ancient rock landslip,it has the typical noticeable features of landslip landform, the collapsing and scattering rocks cover on the peripheral ancient landslips,the Ganqiuchi Pool is a drawn and extended depression,and not a barrier lake formed by falling deposits. A typical mud-gravel structure can be seen at the Shuiqiuchi Pool dam,it was piled up by debris flow deposits,and its formation is not related to mountain falling. From the viewpoints of spatial distribution and the order of the deposit layers, all the collapsing and scattering rocks in the geo-park were formed while occurring the landslide and debris flows. The collapsing rocks are different in sizes and forms from the different places,and the collapse deposit rocks around the geo-park formed due to the various causes and in the different period. These conceptions are fairly important to the scientific cognition and the development of tourism based on the geological remains.
