The term “Sherman-type ore” was initially applied by Behre (1953) to silver-base metal deposits in the Mosquito Range which share the following characteristics: 1)abundant, white bladed barite which was deposited prior to most of the sulfides and sulfosalts; 2)widespread galena and sphalerite which was deposited upon or replaces the barite; 3) light olive-green sphalerite; 4) quartz with minor pyrite may be present and preceded barite deposition; and 5) ore deposits occur as both tabular bodies and replacement veins in the Mississippian Leadville Dolomite. Behre (1953) believed that the above features were sufficiently characteristic to merit the use of a type name for such-ores the Sherman type of ore. Since Behre's definition, there have been numerous studies of this type of deposit both in the Mosquito Range and elsewhere in Colorado.
