Trace-Element Content of Bituminous Coal from Appalachian and Eastern Interior Regions and Rocky Mountain Coal Province--Data as of 1979: ABSTRACT

Autor: Peter Zubovic, Charles L. Oman, A. L. Medlin

Publikováno v: AAPG Bulletin. 64

We have studied 2,035 samples from the Appalachian bituminous coal beds, 370 samples from the eastern interior coal beds, and 362 samples from the Rocky Mountain coal beds. The coals analyzed range in rank from high-volatile bituminous to low-volatil

Distribution of minor elements in some coals in the Western and Southwestern regions of the Interior coal province

Autor: Nola B. Sheffey, Taisia Maximovna Stadnichenko, Peter Zubovic

The average minor-element content was determined in 48 columnar samples of coal of Pennsylvanian age and in 4 samples of lignite from rocks of Eocene age. These samples were collected from Iowa, Missouri, Oklahoma, and Arkansas in the Western region
