Abstract

ABSTRACT: This study is the detailed publication concerning the origins of trace elements in Huanglong Jurassic coal. Forty-two coal samples were collected from Huanglong Jurassic coalfield. Twenty-two elements, including U, B, F, Hg, Be, Cd, Cr, Cu, Mn, Mo, Ni, Pb, V, Zn, Ba, Co, Ga, Sr, As, Se, Cl, and P, were determined. The element profiles were compared with the organic petrography, and the statistical analysis was also carried out to provide preliminary information for origins of the trace elements. The following conclusions were obtained: Cd, Cr, Cl, Ni, Zn, Co, Ga, Sr, As, Se, and B show inorganic affinity. Hg, V, Be, Cu, Pb, and F show generally vitrinite affinity, suggesting that their origins are associated with parenchymatous and woody tissues of roots, stems, barks, and leaves composed of cellulose and lignin. U shows inertinite affinity, which indicated that wood and leaf tissue weakly altered by decay or by biochemical alteration are the main origins of U. P, Mn, Mo, and Ba show overall mixed affinities, indicating the complex of biological origins.
