Regional Distribution of Hazardous Elements in Late Permian Coal Southern Sichuan, China

Abstract:

In this paper, the regional distribution of six hazardous elements (S, Cl, Hg, Se, F and As) in Late Permian coal in southern Sichuan, China, is discussed based on the differences of the sedimentary environment. Based on the different sedimentary facies, the sedimentary environment of the southern Sichuan coal basin can be divided into three areas: fluvial or swamp (AreaI), tidal flat (AreaII) and marine carbonate platform (Area III). The content of F, Hg, Cl and Se is lower in the entire southern Sichuan coal field as compared to the average value of these hazardous elements in Chinese coal. The element S is concentrated in coal in Area III and the upper part of Area II. The element As is concentrated in coal in the upper part of Area II.
