Peat depositional environments, the sites where and conditions under which peat
accumulates, significantly influence a resultant coal's physical properties, chemical …

Organic petrology developed as coal petrology at the beginning of the 20th century
dedicated mainly to the study of coals because of their utilization in industry. Coal petrology …

The dominant plants of the Late Carboniferous lowland tropics were taxonomically and
structurally distinct from those of any later time periods. Dominance was distributed among …

Abstract The Frenkel–Halsey–Hill (FHH) model is one of the important methods of obtaining
the specific surface fractal dimension (DS) of complex fractal porous media. Specific surface …

Coal composition was investigated by means of photometric and maceral analyses on
closely spaced lithotype-based strip samples over the full thickness of several paralic coal …

The composition, rank, coal facies, and coal pore structure characteristics of 15 coal
samples were investigated systemically using methods of lithotype analysis, maceral …

Tar-rich coal, abundant in northwestern China, undergoes variations in the coal-forming
environment, resulting in diverse occurrences of tar-rich coal and its molecular structures …

This study focuses on ascertaining controlling factors and differences on mineralogical and
elemental contents for reconstructing palaeoenvironmental conditions of both seams …

Coalbed is the carrier for coalbed methane (CBM) enrichment and migration. The pore
structure characteristics of coal and their main geological controlling factors are critical to the …

A set of 11 Bolsovian coal seams from the German Ruhr Coal Basin were analyzed in
profiles for their organic geochemical and petrographic composition, aiming at the …
