北淮阳构造带前中生代地层单元及其相关问题 - Abstract according to the " stratigraphic guide of china and its explanation " and based on the general rules for naming stratigraphic units and the principles of priority , a fairly detailed discussion is made on the correct use of the formation - rank names of the lithostratigraphic units of the mesozoic paralic facies of the longzhaogou group in the east of heilongjiang province
摘要以《中国地层指南及中国地层指南说明书》 （修订版）为依据，以地层单位命名的一般规定为准绳，以地层单位命名的优先权为法则，对黑龙江省东部地区中生代晚期海陆交互相地层龙爪沟群组级岩石地层单位名称的正确使用问题，进行了较为详细的讨论。 - In this paper , the authors prove the sedimentary environment of every lithostratigraphic unit of devonian , and precisely divide the geomorphic units of petrologic paleogeography of that period , based on the multiple division and detailed study to the petrostratigraphy , biostrtigraphy and sequence stratigraphy of devonian in hubei and its adjacent provinces
摘要通过对湖北及邻省泥盆纪岩石地层、生物地层与层序地层进行多重划分对比和详细研究，以大量实际资料确定该时期各岩石地层单位的沉积环境，准确划分出该时期岩相古地理地貌单元。 - The further study shows that the sandstones at the bottom of the lower ganchaigou formation , which is a tr lithostratigraphic unit , were deposited in different stages of base level cycle , and they are not chronostratigraphic unit . so , to identify different sequences , especially high order sequences in analysis of terrestrial stratigraphic sequences , the sequence distribution feature must be fully consided . this view has practical significance for recognizing forming , evolution and filling history of qaidam baisn correctly , and has both theorical and practical meaning for directing further oil exploration
研究还表明，传统岩石地层单位中下干柴沟组底部的砂岩代表了基准面变化旋回不同阶段沉积的产物，它们属于不同的成因单位，也非等时地层单位，因此，在进行陆相层序地层分析时，各级层序尤其是高级层序的识别要充分考虑面上的层序展布特点，这一观点对正确认识柴达木盆地的形成演化和沉积充填历史，指导今后的勘探具有一定的理论和实际意义。
