Through investigation and analyses of sedimentary settings especially the provenience of sediments, the Sinian-Jurassic sedimentary strata exposed in the study area have been recognized as Sinian-Lower Triassic passive continental marginal sequences and the Middle Triassic-Middle Jurassic foreland basin sequences. And then, it is inferred that the collisional orogeny in the Dabieshan orogen took place in the Middle Triassic.

波浪作用可以侵蚀浪基面附近的三角洲前缘砂体，并在回流作用下携带至最大浪基面之下再沉积，沉积过程中形成小型浊积体。

Various kinds of water rippleswere formed on the sediments,including straight-crested,undulatory,lingoid and rhomboid ripples by the action of water flow.

Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.
