本文从沉积学、地层学、地貌学、考古学和历史地理学角度，综合分析了太湖的成因和演变。认为地壳沉降与海面上升是构成江南碟形洼地的内外动力，为太湖的形成奠定了基础。全新世海侵最盛时，太湖海湾水深潮急、泻湖、滨海沼泽围绕海湾分布。随南部湾口沙嘴封堵，海湾趋于消失，陆地扩大，遗址增多。3700a来，海面回升，湖面逐渐扩展，形成现代太湖。

Previous studies indicate two possibilities of the formation of the greigite: 1 the seepage of seawater during the postglacial transgression provides sulfate and makes the reducing diagenetic conditions; 2 it may be precipitated as the authengenic mineral in marine or lacustrine sediments during the low sea-level stand of the Late Pleistocene.
