The depositional facies were predicted based on the facies model of the deltaic-lacustrine depositional system given the tendency of the MS ratio.Clays and clay minerals occur under a fairly limited range of geologic conditions. The environments of formation include soil horizons, continental and marine sediments, geothermal fields, volcanic deposits, and weathering rock formations. Most clay minerals form where rocks are in contact with water, air, or steam.

Mud suggests lower-energy processes, whereas the abundance of grains suggests higher-energy processes. 1. Introduction. Coal beds and oil shale are two types of sedimentary rocks formed in different depositional environments. Peat swamps (coal bed) were present between water and dry land (Diessel, 1992), while oil shale was formed by the preservation and aggregation of algae in deep-water environments (Cameron et al., 1994).Obviously, depositional conditions vary within an environment and the suite of sediments can vary or be incompletely developed, but where the sediment suite is present it provides a reliable indicator of depositional environment.
