ASSESSMENT OF THE COAL RESOURCES OF THE KYRGYZ REPUBLIC:

COAL CHARACTER AND DISTRIBUTION, GEOLOGY, MINING, AND IMPORTANCE TO THE NATION'S FUTURE

USGS Open File Report 97-137A (English)

Table 8. Maceral group percentage in coals sampled by the USGS in Kyrgyzstan. Point counting on polished sections of crushed splits of each sample was done by N. Bostick, USGS, under white light. Mineral matter and mixtinite was counted at the same time, and the calculations of mineral- or mixtinite-free basis at the right of the table used these counts. Mixtinite is very fine organic matter, which can not be identified reliably by optical microscopy, mixed with some fine mineral matter.

Area percents calculated from point count as estimated volume percents.
1 = [Mnl / (Mnl+Vt+In+Lpt+Mxt)] 100 = mineral %
2 = [maceral type / (Vt+In+Lpt+Mxt)] 100 = % maceral type Mnl free
3 = [maceral type / (Vt+In+Lpt)] 100 = % maceral type Mxt & Mnl free
4 = [Mnl / (Mnl+Vt+In+Lpt)] 00 = mineral % Mxt free
