ABSTRACT The mineralogy and mineral chemistry of the hard, compact and heavy sulphide patches, found
along with lignites of Neyveli, Tamilnadu, India was investigated by optical and electron probe
microanalysis. These sulphide boulders consist mostly of marcasite, pyrite and rarely pyrrhotite.
Presence of gold in rare and trace quantities from the marcasite of these sulphide patches is
reported here for the first time. If this gold content evaluated properly and recovered
economically and in an environmental friendly way it adds up to the revenue of the mining
company as well as stop the environmental degradation. If marcasite is left as waste, then it may
add up to the environment as acid mine drainage.
