Abstract
Electron Spin Resonance (ESR) studies have been carried out on Tertiary sediment collected from Mae Moh basin, well known for its lignite mining in Lampang province of the northern Thailand, a stratigraphic bedding plane in the sediment that formed in geological time of about 13 million years ago. Each individual sedimentary bed has its own unique assemblage and occurs in a stratigraphic succession which allows for close stratigraphic correlations to be made within the Tertiary of Mae Moh Group. The ESR spectra of sediments confined within the basin at the stratigraphic depth between 100 m and 800 m were carried out. The ESR spectra corresponding to Fe3+, Mn2+, SO-3, SO-2, CO-2, CO-3 and E’1 were observed. This result indicated that the sediment consisted of iron oxide (Fe2O3), quartz and calcite (CaCO3).
