| 摘 要： | 根据江西省6655件上古生界沉积岩样品密度数据统计结果，建立了从陆相沉积到海相沉积其岩石密度增大的宏观模型，并用之分析了泥盆系、石炭系、二叠系和三叠系的密度空间分布特点及所表示的岩相古地理意义，由此探讨了江西省主要成煤期的陆、海分布轮廓，提出了石炭纪、二叠纪、三叠纪靠近古海的滨海盆地和三叠纪位于内陆的山间盆地是本区煤田聚集的有利地区。

| Abstract: | On the basis of the statistical results for the 5588 data of the Upper Palaeozoic sedimentary rock density in Jiangxi,the macroscopic pattern,in which the rock density increases generally from the continental deposit to the marine,has been established.The density spatial distribution and its paleo-geographical implication during the Devonian,Carboniferous, Permian and Triassic periods had been analyzed combing with the pattern.Thus,the sea and land sketch in main coal-forming periods was discussed, and the viewpoint was suggested that the potential coal-accumulating zones might occur in the inshore Carboniferous, Permian, Triassic basins and the inland Triassic intermontane basins. |
