The barite veins strike to the northwest parallel to the enclosing sedimentary hosts. Elevated inclusion temperatures and field mapping suggest the barite is clearly epigenetic and lies along a northwest trending fault. Locally, the barite follows a sedimentary contact, but in general the veins dip more steeply to the southwest crosscutting the sedimentary layers. Furthermore, the vein footwall is slickensided. Due to the small size of the inclusions accurate freezing stage measurements were impossible and salinity could not be determined.
Field observations suggest barite was emplaced at very shallow depths.
The veins crosscut the Waterman Gneiss at steep angles and postdate a prominent mylonitic fabric. Vein contacts are slickensided suggesting emplacement within fault zones. The latter relationship requires significant unroofing of the Waterman Gneiss and transformation from ductile mylonitic fabric to brittle deformation and high angle faulting. Barite occurs as rosette-shaped aggregates, often heavily iron stained. There is no evidence of fluid boiling.
