岩相、古地理(或称沉积相古地理)研究,是通过对古代沉积岩的研究并与现代沉积类比,辨认其沉积相,从而恢复当时的沉积古地理景观。全国性的岩相古地理图,过去刘鸿允先生和原北京地质学院地史教研室各编过一套概略比例尺图集,1979年在中国地质科学院主编的《中国地层》中,每个时代附了古地理略图。岩相、古地理研究与编图工作是一项重要的基础地质工作。近年来,地质部系统组织了一些地质调
The study of lithofacies and palaeogeography (or sedimentary facies palaeogeography) is based on the study of ancient sedimentary rocks and its analogy with modern sediments, identifying the sedimentary facies and restoring the sedimentary paleo-landscape at that time. National lithofacies paleogeographic maps, past Liu Hongyun and former Beijing Institute of Geology history department of each compiled a set of approximate scale atlas, 1979 Chinese Academy of Geological Sciences editor of the “Chinese strata”, each era attached to the ancient Geographic map. Lithofacies, palaeogeography and mapping work is an important basic geological work. In recent years, the Department of Geology organized some geological adjustments
