Analysis Of Heavy Minerals In Arenaceous Lutites From The Northern Canada Basin, Arctic Ocean, Kim Zauderer
Analysis Of Heavy Minerals In Arenaceous Lutites From The Northern Canada Basin, Arctic Ocean, Kim Zauderer
OES Theses and Dissertations
Heavy minerals from arenaceous lutites in three widely spaced cores from the northern Canada Basin were analyzed for the first time to determine the provenance of these sediments. The abundant minerals (sp. gr. == 2.70) in decreasing order for most samples were detrital carbonate, micas, clinoamphibole, clinopyroxene, garnet, epidote, tourmaline, and chlorite. The majority of pyroxene grains were etched. Sedimentary sources dominated and metamorphic and igneous sources were important but secondary. The northern Canada Arctic Archipelago and northern Greenland is proposed as the provenance for the heavy minerals in the arenaceous lutites for at least the past three million years. …
A Search For Ddt Residues In The Juneau Icefield, Alaska, Jon Edwin Barber, Russell S. Adams Jr.
A Search For Ddt Residues In The Juneau Icefield, Alaska, Jon Edwin Barber, Russell S. Adams Jr.
Journal of the Minnesota Academy of Science
The objectives of this study were: 1) to determine if DDT residues occurred in the ice of the Juneau Icefield, and 2) to devise a simple, inexpensive method of sampling glacial ice for pesticide residues. No DDT was found in the samples of ice collected strata spanning the 1963 to 1970 period. However, phthalate plasticizers were found in all samples and were assumed to be· due to contamination during collection. The elution time of the phthalate by gas chromatography was identical to that of p, p-DDT. Conversion of DDT to DDD by ultraviolet light was found to remove the phthalate. …
