北京地质大厦景观石的地质特征

Geological Features of Landscape Stones in Beijing Geology Plaza

北京地貌呈现"北京湾"特征,北山产铁,西山产煤,平原产地热。地质大厦院内东侧花坛摆放代表地球从老到新5个代(宙)的岩石,西侧花坛摆放阳坊花岗岩,体现了地质学为首都城市发展的贡献。太古代密云岩群表壳岩铁矿曾为首钢铁矿的主要原料,元古代雾迷山组汉白玉大理岩曾用于古都北京的建设,古生代马家沟组石灰岩中流出了优质饮用水,中生代窑坡组煤矿使西山成为中国地质工作的摇篮,新生代马兰黄土是中国最早研究的黄土,中生代形成的阳坊花岗岩曾用于北京1959年十大建筑的基石。

The landform of Beijing presents “Beijing Bay” characteristics with iron mine in North Mountain, coal mine in Western Mountain and geothermal fields in Beijing Plain. The rocks in the east of Geology Plaza came from Archaeozoic, Proterozoic, Paleozoic, Mesozoic and Cenozoic Eras; the rocks in west are from Yangfang granite in Beijing. These rocks give expression to Beijing urban geology. Beijing Geological Bureau was set up for iron ore mine in Archaeozoic Miyun Group complex in 1958. Proterozoic white marble embodied Beijing ancient capital features. High quality drinking water drained out of the fissures in the Majiagou Fm. limestone. Beijing Western Mountain was cradle of Chinese geology for Mesozoic Yaopo Fm. coal. The rocks from Yangfang granite were used to Beijing Ten Great Buildings in 1959.
