Abstract
On the basis of integrated logging,seismic data,and drill cores,the high-resolution sequence stratigraphy of the Dongying Formation in the Luda area,Liaodongwan Basin,has been analyzed.Shortterm,middle-term,and long-term base-level cycles have been recognized in the Dongying Formation.The depositional history is discussed under a isochronous stratigraphic frameworks,and a depositional infilling model is proposed.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
