Abstract: This study analyses of trace elements distribution in coal samples from Steenkool Formation in Bintuni Basin, West Papua. The term, trace elements in coal, refers to as those elements with concentration below 0.1 wt. % (1, 000 ppm) in coal that are generally considered to be inorganic he ash content and depositional environment were controlling the amount of trace elements concentration. The trace elements, calcium and magnesium have the greatest organic affinities, whereas, Mn, Mg and Ca have affinities with the carbonates

Keywords: Trace element, ash contents, depositional environment, coal, Steenkool Formation, Bintuni basin
