| 摘 要： | 摘要：巫溪田坝剖面长兴组发育齐全，出露连续完整。根据露头观察和室内镜下岩石薄片鉴定分析，结合岩石学、古生物等沉积相标志的研究，认为巫溪田坝长兴组属碳酸盐台地和斜坡沉积体系，可划分为开阔台地、台地边缘、斜坡相及若干亚相、微相。巫溪田坝长兴组可划分为两个三级层序，每个层序由海侵体系域和高位体系域构成，层序顶底界皆为Ⅱ型层序界面。

| Abstract: | The Changxing Formation is completely developed and fully exposed in Tianba, Wuxi. Field observation and thin section study in combination with sedimentary facies marks indicate that the Changxing Formation belongs to carbonate platform and slope depositional systems which may be divided into open platform facies, platform margin facies and slope facies and subdivided into some subfacies and microfacies. The Changxing Formation can be divided into two third-order sequences. Every sequence is composed of transgressive system tract and highstand systems tract with the sequence boundaries of II-type sequence boundary in top and bottom. |
