| 摘 要： | 本文以本溪组与上覆地层的接触关系和岩性组合、本溪组的沉积层序、微量元素、地球化学相等资料为依据,较为深入地分析了本溪组的环境演化,结果发现,河南登封白坪的本溪组并非长期所认为的简单海进沉积,而是一个以海退为主的沉积层序。

| Abstract: | On basis of the contact relation between benxi formation and its overlying strata, the lithological constitution, the depositional sequence, trace elements and geochemical facies information of benxi formation, its environment evolution has been intensively discussesd. it is suggested that benxi formation in baiping, dengfeng county, is a regression-dominated depositional sequence, not a simple transgressive one as usually regarded. |
