The excessive discharges of nutrients from domestic and industrial effluents, combined with urban and agricultural runoff determine the enrichment of organic and inorganic nutrients in paralic
ecosystems (Borja et al., 2012; Silva et al., 2013).
These coal basins originated from deposition of Carboniferous deposits in paralic
and limnic environments.
The Paleocene-Eocene to Recent Akata Formation is a prodeltaic, mainly marine shale unit overlying the Cretaceous and is overlain by the Oligocene-Miocene to Recent frequent alternations of sands and shales unit, the paralic
Agbada Formation, which is the delta front.

deposits within sequence stratigraphic framework: evidence from the Petrohan Terrigenous Group and the Svidol Formation, Lower Triassic, NW Bulgaria," Sedimentary Geology, vol.
The high ash seems to be due to presence of these coal near margin of swamps and probably the paralic
nature of these swamps give rise to high sulphur, according to calorific value the rank of these coal ranges for subbituminous B to medium volatile bituminous, highest rank in Pakistan coals.
In the early Middle Jurassic (Aalenian - Bajocian), ephemeral coastal to paralic
, brackish to freshwater, environments developed: they consists of well-bedded marly to clayey deposits rich in charophytes, lacustrine ostracods and microflora (Ashraf et al., 1984).

The Lucaogou Formation was formed in a large-scale paralic
lacustrine basin with very high organic matter productivity in a reducing water environment favorable to preservation of organic matter.
