米仓山地区前陆盆地层序地层研究——以吴家垭西部陆相地层为例

STUDYING ON THE SEQUENCE STRATIGRAPHY OF THE FORELAND BASIN IN MICANGSHAN AREA——as an example by the continental strata of the West in Wujiaya

在详细研究米仓山地区吴家垭西部陆相地层基本层序特征的基础上，建立了本区晚三叠世至早侏罗世前陆盆地层序地层格架，确定了盆－山体系在此期间发生了两次重要事件，并认为北部前陆山地的构造变动是影响盆地层序的主要因素。

Based on the seuding of the primary features of continental strata in detail,and it is set up that the sequence stratigraphic framwork of the Foreland Basin in Late Triassic-Early Jurassic Epoch in the western Wujiaya in Micangshan area.The writer defines two important events between the basin and the mountain during this time and belives that the tectonic chang of the foreland mountainous region is main factor affecting the basin sequence.
