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.
