The Occurrence of Glauconite in Monterey Bay, California, Diversity, Origins, and Sedimentary Environmental Significance
James R. Hein (*), Alan O. Allwardt, Gary B. Griggs
Sediment transport, sedimentation rate and the energy due to currents and waves distinguish three distinct environments in Monterey Bay, California: The continental shelf, the continental slope or walls of Monterey Submarine Canyon and the floor of the canyon. Glauconite pellet abundance coupled with its morphologic variability can be used to decipher, and in fact are controlled by, the energy regime of each individual sedimentary environment. Earlier views concerning biotite as a parent material for glauconite and glauconite pellet and mica distribution within this area are not completely supported by this study. Glauconite does not steadily increase in a seaward direction. Pellet morphologies and cleavage studied from scanning electron photomicrographs and X-ray diffraction data sug est several parent materials, even within a single sample.
