Carbonizing Properties: Pocahontas Number 6, Davy Sewell, and Fire Creek Coals from West Virginia and Upper and Lower Kittanning and Upper and Lower Freeport Coals from Pennsylvania

J.D. Davis D. A. Reynolds R. E. Brewer D.E. Wolfson B.W. Naugle

From Forward: value of this survey of the carbonizing properties of American coals by a standard method lies in the comparability of the results on different coals. It must recognized that no standard laboratory method of carbonization, even on a large unit, can yield results that exactly duplicate those obtained in ovens and retorts. The commercial results vary with the type of oven or retort. Allowance must be made for such differences in interpreting the BM-AGA test results in terms of commercial plants.

Carbonizing properties and petrographic composition of Sewell bed coal from Wyoming mine, Wyoming County, WV, and the effect of blending this coal with Alma bed coal

A.C. Fieldner J.D. Davis W.A. Selvig R. E. Brewer C.R. Holmes

This report gives the results of chemical, physical, and petrographic examinations of Sewell bed coal from the Wyoming mine and the yield and quality of carbonization products as determined at low, medium, and high carbonizing temperatures by the Bureau of Mines-American Gas Association (BM-AGA) method. Carbonization tests were made at 500/sup 0/, 600/sup 0/, 700/sup 0/, 800/sup 0/, and 900/sup 0/C in the 13-inch retort, which holds about 90 pounds of coal, and at 800/sup 0/, 900/sup 0/, and 1000/sup 0/C in the 18-inch retort, which holds about 180 pounds of coal. Blending tests, in which 20 and 30% of the Sewell coal was used, were made at 900/sup 0/C in the 18-inch retort with high-volatile Alma bed coal from Boone County, WV. Results of high- and low-temperature assay tests (by the United States Steel and Fischer methods, respectively) are also given. 25 figures.

MICROMORPHOLOGICAL AND ANALYTICAL CHARACTERISTICS OF SOME SOILS FROM DEVON AND KING CHRISTIAN ISLANDS, N.W.T.

Canadian Journal of Soil Science (1975)

S. Pawluk R. E. Brewer

Investigation of soils from Devon and King Christian Islands show frost processes as having a dominating influence upon microfabric characteristics. Frost processes are expressed in the various modifications of banded fabric observed in the soils, and fine-grained cappings on framework members. While soils from Devon Island show little evidence of chemical alteration, the soil from King Christian Island has chemical attributes which reflect desalinization and alkalization processes. Mineralogical weathering is minimal, but the soils can be differentiated on the basis of carbonate rock content and clay mineral distribution. Soils from Devon Island are classified as Regosolic Turbic Cryosols, while the soil from King Christian Island cannot be readily classified in the Canadian system of soil classification.

Definition and use of the term ‘pedoderm’

Journal of Soil Science (1984)

P. H. Walker G. G. Beckmann R. E. Brewer

SUMMARY A new system for soil studies has been proposed by Butler based on his earlier Kcycle concept. In doing so, he has re‐defined ‘pedoderm’, the soil stratigraphic term originally defined in the Australian Soil‐Stratigraphic Proposal (ASSP). Some aspects of soil stratigraphy are discussed and the ASSP outlined. From these considerations we conclude that the re‐definition of pedoderm is inappropriate. We strongly recommend the original definition and usage of the term pedoderm. It was widely discussed among earth scientists and was developed by the careful testing of a number of alternative proposals. The term with its original definition has recently been adopted by the INQUA/Paleopedology Working Group on Soil Stratigraphy.

GLAEBULES: THEIR DEFINITION, CLASSIFICATION AND INTERPRETATION

Journal of Soil Science (1964)

R. E. Brewer JR Sleeman

Summary A broad group of pedological features has been recognized by their occurrence as three‐dimensional entities embedded in the matrix of soil materials. They have been named glaebules and are divided into sub‐groups on their internal fabric, mineralogy, distinctness as a unit, and shape. These features include nodules, concretions, and septaria which have all been recognized by the petrologist, and pedodes, papules, and glaebular haloes which are newly recognized features. An attempt is made to interpret the origin of these features in terms of processes of formation and inheritance versus formation in situ. This is based on interpretation of the characteristics used for their classification.
