The depositional environment with higher reduction and lower salinity conditions was conducive to the increase in tar yield of coal. This work aims to accurately identify and predict tar-rich coal based on its depositional environment, which provides guidance for its exploration and development.This relationship is important because peat type translates into coal type, and coal types can ultimately be used to infer how and under what conditions the original peat bog formed. In our study, no correlation was found between peat type and depositional environment in the four bogs examined. Moreover, no correlation was found between …Fig. 1). These depositional models, it will be argued, do not encompass all black shale depositional environments created during the course of a basin’s Wilson Cycle, i.e. the plate tectonic process of ocean formation and closure (Dewey and Burke, 1974).
