This compilation represents published geochronological information on rocks from Trans-Hudson Orogen and adjacent Archean Rae craton in Baffin Island, Nunavut. For each dated rock sample, a record containing basic information on geological setting, rock description, sample location, analytical method, age, interpretation, and literature citation is given. The analytical methods included in the compilation are U/Pb, Pb/Pb, K/Ar, 40Ar/39Ar, and Rb/Sr. Accompanying Nd-Sm compilations are available separately on this DVD. The full geochronological compilation also forms part of the Canadian Geochronology Knowledgebase. The majority of published data had locations reported by latitude and longitude or by Universal Transverse Mercator (UTM) coordinates. When no sample location information was given in the original text, coordinates were estimated from available location and geological maps or from aerial photographs. It should also be noted that sample locations given in this DVD are more accurate than those shown on GSC Open File 4931 (St-Onge et al. 2006; GSC Open File 4931).
