摘要:

梁山泊遗迹地处黄淮海平原腹地,精细的地层对比划分和区域沉积环境分析,是梁山泊遗迹内工程开发建设的基础。本文以梁山泊遗迹范围内ZK1~ZK4孔岩心为基础,通过沉积物岩性、粒度、孢粉等指标分析,结合14C测年数据建立的地层框架,提出了该地区新的地层划分方案,还原了黄淮海平原腹地1 ka以来的沉积环境演化过程。通过区域上地层岩性、沉积环境、生物群落及地质年龄四方面的对比,将梁山泊第Ⅰ段及第Ⅱ段划分为白云湖组,第Ⅲ段、第Ⅳ段及第Ⅴ段划分为巨野组。梁山泊第Ⅰ段地层(750~900 AD)沉积环境为浅水沼泽沉积环境,气候寒冷干燥;第Ⅱ段地层(900~1200 AD)沉积环境为扰动深水湖泊相沉积环境,气候由寒冷干燥转温暖湿润;第Ⅲ段地层(1200~1300 AD)沉积环境为河流相沉积环境,气候温暖湿润;第Ⅳ段地层(1300~1500 AD)沉积环境从稳定深水湖泊相沉积环境到扰动深水湖泊相沉积,气候由温暖湿润变为寒冷干燥;第Ⅴ段地层(1500 AD至今)沉积环境从由深水湖泊相转为河流相,气候寒冷干燥。

Abstract:

Lake Liangshanpo is located in the hinterland of Huang-Huai-Hai Plain, the detailed stratigraphic correlation division and regional sedimentary environment analysis can help to construct the project in Lake Liangshanpo.Based on the lithology, grain size, and sporopollen analysis of sediments in ZK1-ZK4 drilling cores of Lake Liangshanpo, along with the results of 14C dating, a new stratigraphic division scheme was established and the sedimentary environment evolution process during the past 1,000 years was reconstructed of Huang-Huai-Hai plain.The Lithostratigraphy, Biostratigraphy, Chronostratigraphy are selected to multiple classify and correlate the strata of Lake Liangshanpo, the results showed that the Ⅰ stratigraphic and Ⅱ stratigraphic belong to Baiyunhu formation; the Ⅲ stratigraphic, Ⅳ stratigraphic and Ⅴ stratigraphic are divided into the Juye formation.The elimate of the Ⅰ stratigraphic (formed in 750-900 AD) of Lake Liangshanpo relatively cool and dry, which was a sedimentary marsh environment; the sedimentary environment of the Ⅱ stratigraphic (formed in 900-1,200 AD) was a deep lake facies, and the climate became warm and humid; during the formation period of the Ⅲ stratigraphic (formed in 1,200-1,300 AD), the climate was warm and humid, and the sedimentary environment was fluvial facies; the sedimentary characteristics found in the Ⅳ stratigraphic (formed in 1,300-1,500 AD) indicate that the sedimentary environment is a disturbed and stable deep lake environment, and the climate changes from warm and humid to cool and dry; the sedimentary environment of the Ⅴ stratigraphic (formed in 1,500 AD till now) changed from lake facies to fluvial facies, and the climate was cold and dry.

Key words: sedimentary environment, stratigraphic division, Baiyunhu formation, Juye formation
