Numerous examples of coke produced by igneous intrusion into coal have been reported in the Spanish Peaks region of south central Colorado. However, in a recent study of an intruded section of the Raton Formation (Upper Cretaceous-Paleocene) along th

Arsenic in the coal studied is not bound to coal macerals, it is concentrated in the inorganic part of coal, specifically in the iron sulfides. This paper reports the results of five crystal structure refinements that include natural (2) and syntheti

The Raton Basin contains a series of Tertiary mafic dikes and sills that have altered millions of tons of coal to natural coke and may have played a minor role in generating some of the large coalbed methane resources currently being exploited in thi

Bituminous cobbles collected from the Fossil Forest site (Geodetic Hills, Axel Heiberg Island, Canadian Arctic) have been subjected to petrographic and geochemical characterization. Transmitted light microscopy and pyrolytic analyses indicate that th

One of the most important parameters characterizing the performance of brake materials is their formulation. Therefore, the precise analysis of brake materials is needed both to investigate formulation-performance relationship, and to maintain qualit

Although bireflectance measurements are routine, to date they have been limited to selected single point measurements. This study uses a 360° rotating polarizer in the incident light path combined with digital imaging to map the optical bireflectanc

The heterogeneity of the 125−212 μm size cuts from four pulverized coal samples from the United Kingdom, United States, and South Africa has been examined in detail by means of density separation and optical and scanning electron microscopy. While
