Geologic map of the Phantom Lake quadrangle, Carbon County, Wyoming
The Phantom Lake 7.5-minute quadrangle is in southeastern Carbon County near the western flank of Medicine Bow Mountains. Precambrian (Neoarchean–Paleoproterozoic) intrusive, metasedimentary, and metavolcanic units are exposed in the northern and south-central portions of the quadrangle, but are obscured by glacial tills and other Quaternary deposits elsewhere on the map. The map area is adjacent to the Cheyenne belt, a 1.7 billion year-old suture zone that influenced much of the mineralization within the Medicine Bows and many of the structural features on the Phantom Lake quadrangle. Whole-rock geochemistry, along with detrital and magmatic zircon geochronology analysis results are reported for the Browns Park Formation and many of the Precambrian formations.
