Geologic setting

Geologic description

Hematite occurs as dark red and black veinlets and as fine botryoidal masses in cavities in brecciated and hydrothermally altered, porphyritic rhyolite, in part of a unit described as rhyolite domes, tuffs and breccia by Patton and others, 1980). Possible dark, oxidized cinnabar also occurs in the veinlets (Patton and Moll, 1983). Three samples contained 0.95 to 3.70 ppm mercury (Patton and Moll, 1983).
