MICROFOSSIL PLANTS IN METAMORPHOSED VOLCANIC SEDIMENTARY ROCK SERIES AT YELE, MIANNING, SICHUAN

Publish Date: 15 February 1999

摘要: 位于扬子地台西缘康滇地轴中段的冶勒变质杂岩体中分布的变质火山沉积岩系，首次发现微古植物化石，计有１１个属３６个种，时代确定为中新元古代蓟县系—青白口系，为岩系的划分及归属提供了依据，证实有褶皱基底的存在。
Abstract: Microfossil plants, including 11 genera, were first found in metamorphosed volcanic sedimentary rock series of the Yele metamorphosed complex in the central sector of the Kangdian （Xikang Yunnan） axis on the western margin of the Yangtze platform, and their age has been determined to be Meso and Neoproterozoic Jixianian Qingbaikouan. This provides evidence for the division and assignment of the rock series and confirms the existence of the folded basement.
