| 摘 要： | 经对赣中西部地区晚三叠世沉积特征及安源煤系沉积相归属问题的分析和讨论,认为研究区的沉积环境为半咸水的陆缘近海湖环境,并可进一步划分出五种亚相,即半深湖亚相、浅湖亚相、滨湖潮坪亚相、湖泊三角洲亚相和水下冲积扇亚相,对各亚相特征进行了系统地描述。

| Abstract: | Though the discussion and analysis on the sedimentary feature of late Triassic in western mid-jiangxi and the classification of the sedimentary facies of Anyuan coal bearing strata, it is found that the depositional environment of late Triassic in the study area is a brackish continental-edge lake, to be further divided into five subfacies: half deep lake, shallow lake, lake tidal flat, lake delta and alluvial fan. The feature of each of the subfacies is decribed in this paper. |
