Biogeochemical Survey over the Eastern Meguma Terrane of Nova Scotia
DP ME 129, Version 2, 2006. Biogeochemical Survey by the Nova Scotia Department of Natural Resources Over the Eastern Meguma Terrane of Nova Scotia, 1987
Abstract
In 1987, a biogeochemical survey was conducted by the Nova Scotia Department of Natural Resources over the Eastern Meguma Terrane of Nova Scotia. Samples were acquired at 2 km intervals along all drivable roads and tracks covering a 5000 km2 area of the eastern Meguma Terrane. A total of 854 locations were visited during a three week period, including detailed sampling at approximately 200 sites over zones of known or suspected mineralization at the Beaver Dam gold deposit. Vegetation sampled included both bark and twigs from balsam fir and red spruce tree species as well as shrub alder twigs.The regional survey of about 600 sites had an average density of 1 per 8.43 km2 and 1 per 46.73 km2 for the balsam fir and red spruce species, respectively. Samples were analyzed for As, Ba, Br, Ca, Co, Cr, Cs, Fe, Hf, K, Mo, Na, Ni, Rb, Sb, Sc, Se, Sr, Ta, Th, U, W, Zn, La, Ce, Nd, Sm, Eu, Tb, Yb, and Lu. This data set was previously included as part of a compilation of geochemical surveys and released as DP ME 004 Version 1. This data set was previously called fir and later renamed c129gycb.
