The environments for the formation of organic material include neritic shelf open water environment and semi-enclosed lagoonal sedimentary environment.
有机质形成环境既有浅海陆棚相开阔型水体环境，也有半封闭型泻湖相等沉积环境。

In the Jurassic and Cretaceous, generally it was also the shelf sea (shallow sea), but there were lacustrine and lagoonal environments in different parts of the basin.
侏罗纪-白垩纪在总的浅海陆棚环境下，盆地不同地区也形成了湖泊和潟湖环境。

It is shown that the correlation based on the net tip resistance has much higher accuracy for estimating the consolidation yield stress of lagoonal deposit soil than other methods.
