翠华山山崩国家地质公园位于陕西省西安市长安县,总面积32平方公里,主要地质遗迹类型为山崩地质遗迹。翠华山距西安约23公里,是终南山的支峰,山上名胜古迹很多,风景如画,因汉武帝曾在此祭太乙神,又称太乙山。 翠华山属秦岭山脉,由中元古界(距今10亿年前)变质杂岩组成,秦岭北麓大断层从山北侧通过。该断层目前仍在活动,其北侧相对下降形成吴中平原,南侧抬升形成高耸立的秦岭,一万年以来平均每年上升1.73-3.4毫米。强烈的断裂活动,加上构成翠华山山体的岩石质坚性脆,又地处地震带且多瀑雨,从而引起山体崩落。这里的山崩地质作用形成了一系列山崩地质景观如:山崩悬崖景观、山崩石海景观、山崩地堆砌洞穴景观、山崩堰塞湖景观、山崩瀑流景观及山崩形成的各种造型奇石景观等。
