| 摘 要： | 形成中国北方岩溶的地层主要为奥陶系马家沟组石灰岩和中元古界蓟县系雾迷山组硅质条带白云岩。上新世石林与第四纪岩溶陡壁组合成的房山地貌主要形成于雾迷山组中,岩溶洞穴发育在马家沟组和雾迷山组中。大石河南岸从上游至下游依次分布鸡毛洞、银狐洞、石花洞、清风洞和孔水洞,由一条地下暗河连为一体,称为石花洞系。石花洞系发育在北岭向斜东北扬起端的马家沟组顶部,与南面的周口店猿人洞系隔着房山闪长岩体。石花洞系中8层不同海拔高度的溶洞可以和永定河的8级阶地进行对比,也可以和8个华北地文期对比,代表了与之相互对应的北京西山新构造隆升的期次。 |

| Abstract: | The strata formed karst in North China are mainly composed of Majiagou Formation in Ordovician and dolomite with siliceous bands of Wumishan Formation, Jixian System in Middle Proterozoic. The local Fangshan landform is made up of Pliocene stone forest on mountain top and Quaternary karst stone cliffs, all formed within Wumishan Formation. Karst caves are either developed in Majiagou Formation or Wumishan Formation. Shihua Karst cave system along the south bank of Dashi River consists of Jimao Cave, Yinhu Cave, Shihua Cave, Qingfeng Cave and Kongshui Cave, connected by an underground river. Shihua Cave system is developed on top of Majiagou Formation in northeast uplifting limb of Beiling syncline. There is Fangshan granodiorite between Shihua Cave system and another Karst Cave system of Peking Man Site at Zhoukoudian. Eight altitude levels of Shihua Cave system represent corresponding times of the neotectonic movement in Beijing Western Hills. It may correlate with Physiographic Stages of North China and terraces of Yongding River. |
