Petrography, chemical composition, and stratigraphic setting of the coals of North-Central Missouri
type: CreativeWork
description: "Under a grant from the National Air Pollution Control Administration, the Missouri Geological Survey undertook a core drilling program to learn more about the coals in north-central Missouri. The stratigraphic setting and chemical and petrographic characteristics of 43 complete samples of coal recovered from 13 diamond drill holes in the exploration program in north-central Missouri are major contributions of this study. These samples represent twelve different coal beds of the Atokan and Desmoinesian Series of the Pennsylvanian System of Missouri and range in thickness from 9.6 to 44.4 inches. They have an average thickness of 20.4 inches and a combined thickness of 71.8 feet. Detailec lithologic logs of the drill cores are an additional contribution of this investigation. In the seven county area of this report, there are an estimated 15.4 billion tons of coal resources. Of this total about 4.3 billion tons are classified as unmined coal reserves. Proximate and ultimate analyses, BTU and sulfur content including forms of sulfur are given for each of the coals sampled. The BTU content of the coals has an arithmetic mean of 10,447 as received. The arithmetic mean of the sulfur content of the coals is 4.69 percent as received of which 3.26 percent is pyritic, 1.39 percent is organic, and 0.04 percent is sulfate. The weighted average sulfur content based on thickness of the coal is 4.94 percent as received of which 3.37 percent is pyritic, 1.53 per cent is organic, and 0.04 percent is sulfate. The coals studied may be classified as high volatile bituminous. They have an arithmetic mean of 35.9 percent volatile matter and 13.8 percent moisture as received. The arithmetic mean of the fixed carbon content is 36.1 percent. Ash content is quite variable and ranges from 3.6 to 25.9 percent with an arithmetic mean of 11.9 percent. The maceral groups of vitrinite, inertinite, and exinite as well as mineral matter were identified and counted under reflected light from polishe…
