位于皖江北岸的枞阳县境内,濒临白荡湖,与九华山相望,北距合肥120公里,南距枞阳县城27公里。以火山岩洞和摩崖石刻为特色,河湖风光与人文景观交相辉映。浮山火山地貌属典型的塌陷火山洼地,是一座沉睡亿年之久的古火山。在距今1.4亿年至1亿年间的侏罗纪晚期至白垩纪早期的近4000万年时间里,这是发生多次火山喷发,形成了奇特的火山地貌——有复合穹丘、火山口、火山锥、火山渣(浮石)及熔岩流、环状断裂与放射状断裂、龟裂纹等。浮山为白垩纪(距今约1.35亿至6500万年)火山喷发形成的破火山,火山岩韵律层序完整,地质现象典型。另外,浮山的人文景观丰富多采,留下了许多珍贵的文化遗迹。
Zongyang County is located in the northern bank of the Wanjiang River, on the brink of Bai Dang Lake and Jiuhua Mountain, 120 kilometers north of Hefei and 27 kilometers south of Zongyang County. With volcanic caves and cliff stone features, rivers and lakes scenery and cultural landscape pavilions. Fushan volcano landform is a typical depression volcanic depression, is a sleeping volcano for hundreds of millions of years. In the nearly 140 million years from the Late Jurassic to the Early Cretaceous from 140 million to 100 million years ago, there were many volcanic eruptions that formed peculiar volcanic landforms - compound domes, crater , Volcanic cone, volcanic slag (pumice) and lava flow, annular fracture and radial fracture, turtle cracks and so on. Fushan Cretaceous (dating back about 135 million to 65 million years ago) volcanic eruption formed volcano, volcanic rock rhythm complete sequence, the typical geological phenomenon. In addition, Fushan cultural landscape rich, leaving many precious cultural relics.
