Coal depositional environment.
The percentage of maceral of a coal seam has a firm connection to depositional facies when the peat and coal accumulated, so maceral analysis could used to reconstruct be the coal depositional environment. Coal samples were obtained from the core of a borehole. From this core, some samples were taken to laboratory to conduct maceral analysis.
vestigate coal depositional environment. This paper will emphasize most of the coal petrographic data within the Berau Coal Measures, located in Lati, Sambarata, and Binungan regions (Figure 1), related to its palaeodepositional envi-ronment. The data presented here are discussed in terms of two geological problems, such as: (1) Are Coal facies refers to the genetic type and coal rock type of coal formed in a certain depositional environment. Rare earth elements (REE) are not easily disturbed by metamorphism, which is used to determine the provenance characteristics of coal-forming materials and the depositional environment in the coal seam.Coal mining - Extraction, Processing, Pollution: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is …Sabkha. Sabkhas are hydrological settings where resurging groundwater form displactive and replacive evaporite minerals in the capillary fringe above a saline water table or in the brine-saturated muds immediately below (Warren, 2010), which are usually distributed in the uppermost interval of tidal flat environment (supratidal zone) in relatively arid climate.

The distinction between coal-bearing upper and lower delta plain deposits in the rock record may be based on the presence or absence of features indicative of basinal influence, and on the geometry of coal seams.Variations in coal accumulation in different parts of rift basins are considered to be controlled mainly by differences in subsidence and depositional environment (Fielding, 1984 (Fielding, , 1987 ...
Coal is known to concentrate many elements, for example Ge, U, and Se (Goldschmidt, 1954; Swaine, 1990). This is partly due to the interactions of organic matter in a reducing environment with solutions entering the swamp, precipitation of minerals, breakdown of other minerals, along with the concentrating effect of some plants and the potential for …Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form . Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Coal is also called black gold.Depositional environments. Sedimentary rocks are formed by 5 processes, there are erosion, weathering, transport, deposition, and diagenesis process (Boggs, 1991). These 5 processes with 4 types of rocks make up a cycle that is known as sedimentary cycle.
