Abstract: On the base of systematic field works and analysis of test in laboratory,this study summarized characteristics of petrography,organic geochemistry and hydro-liquefaction of hydrogen-rich coal in Fushun Basin,and made an inquiry into formation conditions of hydrogen-rich coal.The lithofacies types of Fushun coal are very abundant.19 types of lithofacies have been identified in terms of macroscopic petrographic composition and structural type of Fushun coal.The maceral of Fushun coal is generally characterized by high vitrinite and low inertinite and exinite contents,but in some special lithotypes,for example,amber coal and humic-sapropelic coal,the former contains abundant resinite and the latter is mainly composed of fragmental vitrinite and high degraded filamentous algae.The rank of Fushun coal is mainly subbituminous and high volatile abituminous.Fushun coal is of good liquefaction quality and relatively-excellent liquefaction coal.Fushun coal was formed in a warm and humid forest swamp with deep overlying water and rich resin,and a tectonic condition of rapid subsidence.
