| 摘 要： | 关于北京“洼里砾岩”的争论由来已久，有构造成因和沉积成因两种不同的成因观点。文章在前人资料的基础上．结合近年北京地区地热地质成果和地热钻井资料，分析了砾岩的形成环境，提出“洼里砾岩”，代表一个时期的沉积间断或剥蚀时期，反映了一个不整合界面的存在，属于“复成分”砾岩，具有底砾岩性质的沉积砾岩。 |

| Abstract: | The argument about Beijing Wali Conglomerate has a long history with the two different viewpoints respectively being tectonic genesis and sedimentary genesis. Based on former researchers＇ data, combined with recent geothermal geological fruits and geothermal drilling data in Beijing area, it has analyzed the forming environment of conglomerate, and pointed out that Wali Conglomerate, which represents a period of sedimentary hiatus or erosion and reflects the existence of an unconformity surface, belongs to composite conglomerate and is a kind of sedimentary conglomerate owning properties of basal conglomerate. |
| Keywords: | Wali Conglomerate gravel characteristics forming environment Beijing |
