Geological context: The schistose rocks in which the cinnabar occurs strike generally NE-SW, and the planes of schistosity are nearly vertical. The southwestern part of this schist belt is divisible longitudinally into at least eight zones, which are, from SE to NW:
1. Gray sericitic schist (first crossed ascending the west form Sycamore Creek)(about 1½ miles wide);
2. Dikelike mass of yellow rhyolite porphyry, perhaps 1/3 mile wide;
3. Fissile brown slate (between 1/3 & ½ mile wide);
4. Sericitic schist (same width) containing here and there layers of squeezed conglomerate, of slate, of interlaminated hematite and jasper, of limestone, and of greenstone schist. This is the zone in which most of the cinnabar deposits in Maricopa County have been found (MARICOPA COUNTY BELT).
5. Thin layers of yellowish dolomitic limestone and bright red jasper (jasper zone), forming prominent outcrops;
6. Schist, although similar to that on the SE side of the jasper, appears to contain a larger proportion of squeezed grits and conglomerates;
7. A second zone of brown slate;
8. Second zone of rhyolite porphyry
It is seen that in the SW part of the mercury belt the distribution of the rocks is such as to suggest that the jasper zone occupies the axis of a compressed syncline or anticline.
In Gila County, east of Pine Butte, the mercury deposits appear to occur in the southeast schist zone (GILA COUNTY BELT), the one crossed first in the ascending Sycamore Creek, and therefore not the same zone as that containing the deposit on the west fork of Sycamore Creek
