The
objective of GeoFile 2005-13 was to collect and process glaciofluvial sands and
gravels to analyze for the presence or absence of kimberlite indicator minerals (KIMs) in the Fort
Nelson area. Of 20 samples collected and processed, 14 contain KIMs such
as purple pyrope,
yellowish eclogitic garnet, Cr-diopside, olivine, ilmenite, or spinel. It
is possible that these minerals are derived from primary, secondary or tertiary sources
within the Fort Nelson area. It is also possible, however, that they were
brought intothe
region from the Northwest Territories and Alberta by Late Pleistocene
glacial and glaciofluvial systems.
All publications of the BC Geological Survey are available
for purchase through Crown Publications Inc. (and its agents).
