Abstract	The Bake quartz vein-type gold deposit is one of the most well-known gold deposits in SE Guizhou. The mineralization age of auriferous arsenopyrite determined using Re-Os chronology is 412 +/- 21 Ma (MSWD = 2.6), which is in good agreement with the regional-scale geologic evidence and confirms that the Caledonian was an important gold metallogenetic period in the Xuefeng region. Contrastingly, the high initial Os-187/Os-188 ratio (2.7 +/- 1.2) suggests a crustal source for the ore-forming material of the deposit. Furthermore, the REE patterns, Eu/Eu, Ce/Ce and Y/Ho ratios of the arsenopyrites are all similar to those of the wall rocks, indicating that the ore was perhaps derived from the wall rocks belonging to the Xiajiang Group.
