甘肃省文县地处秦岭山脉,地层为浅海相沉积,主要以灰绿千枚岩、碳酸盐岩、含铁石英岩为主,境内富含金、锰、铜、铁、钒等各种矿产资源。该地区属新构造运动强烈区,地震活动频繁,地质构造复杂,地表起伏大,形成了悬崖峭壁林立,高山峻岭重叠,峰谷交错纵横的地貌特征。白龙江尤如一条蜿蜓飘逸的玉带,盘曲于甘肃、四川两省的崇山峻岭之中,全长576公里,天然落差2671米,最大洪水流量3260立方米/秒,江中盛产砂金,仅百余公里段便含金储量十余吨。
Wenxian County, Gansu Province is located in the Qinling Mountains, the strata are shallow marine sediments, mainly composed of greywild phyllite, carbonate rock and ferri-quartzite. The territory is rich in gold, manganese, copper, iron and vanadium mineral resources. The area is a strong area of neotectonic movement, seismic activity is frequent, complex geological structure, surface ups and downs, forming a cliffs, mountains and mountains overlap, peak and valley staggered aspect. Bailongjiang is like a jagged tropical jade belt, winding in Gansu, Sichuan Province, among the mountains, a total length of 576 km, the natural gap of 2671 meters, the maximum flood discharge of 3260 cubic meters / second, the river is rich in gold, only 100 kilometers Paragraph gold reserves of more than ten tons.
