Sinclair ... [et al.]. Ottawa : Natural Resources Canada, 2014. [6] p. : table. Open file (Geological Survey of Canada) ; 7688 Includes bibliograhic references. This data set depicts the spatial distribution and most significant descriptive attributes of tin and tungsten deposits world-wide. The majority of these deposits are associated with felsic to intermediate intrusive igneous rocks. Variations of this class include mineralized stockworks and veins, greisens, skarns, and replacement deposits in predominantly carbonate-rich sedimentary rocks. Significant tin and tungsten deposits also occur as placer deposits and as volcanic-associated deposits. This database has been compiled primarily from published literature and, in the absence of published references, from the personal knowledge of the compilers. gccst Geology gccst Databases Sinclair, W.
