Five of the eight coals to be studied in this project have been selected on the basis of economic importance as well as geologic and chemical histories. Plans have been initiated to collect the first sample, a Pittsburgh seam coal from southwestern Pennsylvania. However, we have as yet not received permission from the mine to collect our working face sample. In addition, preliminary work was completed on development and testing of a procedure to photo-oxidize vitrinite containing coal blocks using the optical microscope
