The Organization of Sedimentary Rocks
SEPM Journal of Sedimentary Research, 1950Attempted practical applications of existing classifications of sedimentary rocks commonly encounter difficulties and inconsistencies: (1) sediments normally unassociated during deposition are artificially grouped together; (2) inferences about environment, degree of tectonic influence, and other factors not everywhere legible in the rocks are required

Zeolites in Sedimentary Rocks [PDF]
SEPM Journal of Sedimentary Research, 1959 ABSTRACT Zeolite minerals, especially analcime and clinoptilolite, are known to occur widely in sedimentary rocks both as nearly monomineralic beds and as accessory minerals. Because of the extremely fine grain size of the zeolite rocks, identifications are made most readily with X-ray diffraction techniques.

A Classification of Sedimentary Rocks
The Journal of Geology, 1948A simple field and laboratory classification of sedimentary rocks is proposed. It is based fundamentally on composition and texture, with the primary divisions determined by the mode of origin of the constituents. Tt is tripartite in nature, consisting of (1) a dominantly fragmental division, including conglomerates, sandstones, and shales; (2) a ...

Recycled detrital quartz grains are unequivocally identified if there are overgrowths on abraded overgrowths. We argue that the presence of such recycled grains even in small quantities in successions of quartz arenites indicates derivation from one or ...

Dechlorinating microorganisms in a sedimentary rock matrix contaminated with a mixture of VOCs.
Environmental Science and Technology, 2012Microbiological characterizations of contaminant biodegradation in fractured sedimentary rock have primarily focused on the biomass suspended in groundwater samples and disregarded the biomass attached to fractures and in matrix pores.

Sedimentary Rocks and the Oceans
1972Interest in the isotopic composition of strontium in sedimentary rocks is increasing rapidly. Recent work includes dating of argillaceous sedimentary rocks as well as studies of the variation of the 87Sr/86Sr ratios of the oceans in the geologic past. While much progress has been made, many challenging problems remain to be solved.

Copperwood is located in Gogebic County, Upper Peninsula, Michigan, within the Porcupine Mountains copper district. It was discovered in 1956 and, in 2008, Orvana Minerals Corp began exploration and development work with production projected in the near ...
