| 摘 要： | 昌乐五图煤田和黄县煤田是鲁东地区发现的两个古近纪煤田,含煤地层时代属于中始新世,均为富含褐煤和油页岩的沉积建造。煤系中部均发育一段厚度20～30m的紫红色砂砾岩夹泥岩(或粘土岩),将煤系分为上下两部分;煤系底部为厚层杂色砂砾岩、砾岩和角砾岩等粗碎屑岩,具有很好的可比性。推断在黄县煤田向西到羊角沟沿海一带,五图煤田以东的潍坊—昌邑一带和以西的昌乐、临朐、益都等地,可能有同层位煤系赋存,建议将这些地区作为找煤重点区域。

| Abstract: | The Wutu coalfield in Changle and the Huangxian coalfield are two Paleogene coalfields found in the eastern Shandong.The age of coal-bearing strata belong to the Middle Eocene Epoch are all rich lignite and oil shale bearing depositional formations.In middle part of coal measures contains a purplish red sandy conglomerate intercalated with mudstone(or claystone),divided the coal measures into two parts.Coal measures bottom part is thick-bedded coarse-grained clastic rocks consist of sandy conglomerate,congl... |
