Title
PRELIMINARY APPROACH ON THE SEDIMENTARY FACIES OF THE WUTONG FORMATION IN CHAOXIAN COUNTY, ANHUI
摘要
分布于巢县北部地区的五通组,其大套成熟度很高的石英岩系,发育的楔状、槽状以及特征的纹层状交错层理,普见的对称浪成波痕和浪成干涉波痕,丰富的垂直和倾斜的虫管构造等沉积特征,均显示其不属于陆相沉积,而是海相沉积,具海岸模式的层序和特点。
Abstract
The Wutong Formation in the north part of Chaoxian County consists of a large series of highly matured orthoquartzites, in which wedge-shape, troughshape and characteristic laminated cross-stratigrafication developed, symmetrical and interfering wave ripples and abundant vertical and inclined burrows occurred very often. These characters show that the Wutong Formation is not a continental but marine facies with evident sequences and characters of shore model.
