江苏阜宁西园剖面全新世风暴控制相的沉积构造与沉积构造相

SEDIMENTARY STRUCTURES AND STRUCTURE FACIES IN THE HOLOCENE STORM-CONTROLLED FACIES, XIYUAN SECTION, FUNING COUNTY, JIANGSU PROVINCE

本文记述了江苏阜宁西园剖面全新世风暴控制相的沉积构造类型及沉积构造组合。同心注模、相干层理、枝状泥波痕交错纹理、格子状构造等属于新鉴定的且与波浪作用有关的沉积改造也即波控构造,文中给出了它们可能的成因解释。在此基础上,作者恢复了西园剖面风暴控制相的沉积构造相,并建立了该风暴控制相的沉积构造相相模式。

The Holocene storm-controlled facies of Xiyuan section, Jiangsu Province, is described and discussed mainly in the aspects of sedimentary structures and their associations. Concentric projections, intervened beddings, bifurcated muddy wavy cross-ripples and check-wise structures are recently found having relationship to wave process and hence called wave-controlled sedimentary structures. This paper also gives possibly genetic explainations of sedimentary structures, by which the structure facies is constructed and its model eventually rebuilt.
