| 摘 要： | 早白垩世晚期江西贵溪盆地的控盆断裂活动加强,在盆地边缘的不同地带及盆地中心发育有不同的沉积体系,野外露头岩相特征和剖面的研究表明,贵溪盆地罗塘群主要发育有冲积扇体系、扇三角洲体系、辫状河三角洲体系、湖泊沉积体系及辫状河沉积体系,沉积体系特征主要受控于盆缘断裂活动,不同的沉积体系出现在盆地演化的不同阶段,并由不同的岩相组成.沉积体系的特征、分布及组合型式反映了陆相断陷红盆沉积相带窄、横向及纵向上相变快的特点.

| Abstract: | At the edge of Guixi basin, the fault that controlled the forming of the basin become more active in the late period of Early Cretaceous. At the different edge and the center of the basin , it develops different sedimentary system . The study of lithofacies characteristic of outcrop and profile shows that Luotang group in Guixi basin develops alluvial fan, fan-delta, braided-river delta, lacustrine and braided-river sedimentary system. The fault, at the edge of the basin , controls the sedimentary system feature. In different evolutionary stage of the basin ,it develops different sedimentary system, and combined by different lithofacies. Sedimentary system feature, distribution and combination show that the narrow distribution facies and abrupt changes in facies in lateral direction and long direction in faulted basin. |
