Abstract

The microstructural details of woody lignite from the Darrang district area in Assam have been studied; the lignite is derived from the secondary wood of a dicotyledonous angiosperm. Xylinite and resinite (brown and yellow resins) are the main petrological constituents. The common occurrence of resins accounts for the high volatile content of the lignite. Films of clayey matter occupy the fracture and joint planes and account for the variable proportion of ash content. Sulphur is low, which indicates formation of the lignite in conditions other than marine.
