چکیده
This report describes a new pyroxmangite-rhodonite occurrence visited briefly by the authors as part of a broader study o,f gemstones in British Columbia. The discovery is on the Cl-t claims, 1.5 kilometres northwest of Mount Roderick Dhu (lat. 49”12’, long. 118’37’), 13 kilometres northeasi of Greenwood (Figure 1). Rhodonite is a manganiferous semiprecious stone valued for its pink to deep red colour. After jade, rhodonite is the second most important gemstone found in British Columbia. Lower quality material has ornamental applications such as sculptures, table tops and a variety of decorative items. Other occurrences in the province have been described by Leaming (1966), Danner (1976), Danner and Cowley (1980), Cowley (1979), Hancock (1992), Nelson et al. (1990) and others, Other pink manganese silicates that are difficult to distinguish from rhodonite are pyroxmangite and bustamite. It is possible that these minerals also occor in other previously known rhodonite occurrences but were not distinguisheri from rhodonite.

This Extension Note describes some effects of clearcut harvesting and broadcast NPS fertilization on nitrogen (N) mineralization and components of the soil food web at three sites in the ICHmw subzone. We found that the forest floor in clearcuts had lower fungal hyphal lengths, total microbial biomass, microbial biomass N, and potential N mineralization than the forest floor in adjacent forests...
