Paleo geological

The delineation of local traps was facilitated by combining the stripped-off paleo-geological map with the map of the present structure. In this way we were able to exclude certain disturbed portions of wedge zones where the traps have been destroyed by later tectonic movements.

Recently, mass-dependent isotopic variation for molybdenum has surfaced as a tool of high paleo-environmental potential (Barling et al, 2001 Barling and Anbar, submitted). Specifically, relatively inefficient scavenging of molybdenum from seawater by oxide phases under oxic marine conditions—compared to efficient removal under anoxic settings—yields patterns of molybdenum isotope variabihty in seawater (recorded in the black shales) that may track the global proportion of oceanic anoxia over geological time.

In Labrador, true prehistoric soapstone quarries—as opposed to geological outcrops— where clear evidence of mining or other extractive activities is preserved, have proved to be rather difficult to locate. An exception is the well-documented Fleur de Lys quarry, where Dorset Paleo-Eskimos apparently worked the deposits for many years (3). Quarried zones are found in two discrete localities, referenced as Localities 1 and 2, which are located about 0.5 km apart. The most intensively worked location (Locality 1) consists of a discontinuous series of areas where soapstone was removed, spaced over a distance of 200 m. Preliminary calculations based on the number of preform removal scars and unfinished preforms suggest that material for a minimum of 1000-2000 vessels was mined from this locality alone during the period of time that it was being quarried.
