A new method for predicting the shale distribution of the Wufeng Formation in the Upper Yangtze Region, China [PDF]

BSGF - Earth Sciences Bulletin, 2020
Taking the Late Ordovician Wufeng Formation (WFF) shale in the Upper Yangtze region as an example, we conducted a lithofacies distribution, thickness quantification, and paleo-topographic reconstruction of the Late Ordovician graptolite zones. Specifically, we focused on the Late Katian Dicellograptus complexus and the Early Hirnantian Metabolograptus ...
