| Abstract: | Based on discussion of the distribution of depositional processes in lacustrine system, depositional architecture of 7 depositional packages are described respectively, which include lacustrine delta with distributary mouth bar, lacustrine delta with subaqueous distributary channels , fan-delta , braided delta , lacustrine clastic shoreline , oxygenated deep lake and anoxic deep lake. If the 7 depositional packages are regarded as essential elements which consist of the lacustrine depositional system, 5 basin-fill patterns are recognized, i. e. fan-delta/deep lake and subaqueous gravity flow pattern, fan-delta and lacustrine shoreline/medium lake pattern, braided delta/medium lake pattern, lacustrine delta and shallow lake/medium lake pattern, lacustrine clastic shoreline and delta/anoxic deep lake pattern. |
