【Abstract】 The Wutong Formation in the north part of Chaoxian County consists of alarge series of highly matured orthoquartzites, in which wedge-shape, trough-shape and characteristic laminated cross-stratigrafication developed, symmetricaland interfering wave ripples and abundant vertical and inclined burrows occur-red very often. These characters show that the Wutong Formation is not a con-tinental but marine facies with evident sequences and characters of shore model.更多还原
