X-ray study on Indian lignite


, : X-ray study on Indian lignite. Quarterly Journal of the Geological, Mining and Metallurgical Society of India 31(1): 17-21

X-ray powder diffraction photographs of four lignite samples from the south Arcot district and one from the Palana field are presented. Diffuse diffraction bands at 3.5 A and 2.12 A were observed in all cases. Additional well-defined lines at 4.15 A and 3.76 A were shown to be due to montan wax.
