Comments on the location information

  • POSSIBLY, SOME PLACE ALONG THE CREEK, FOLLOWING A NW-SE FAULT, IS WHERE THE SPECIMENS WERE COLLECTED, SAID TO BE TITANCLINOHUMITE FROM A DIALLAGITE CONTACT ZONE BETWEEN GABBRO AND GRANOPHYRE, VEINED WITH PEGMATITES, ACCORDING TO HUANG (1957, P. 686). ESTES (1980, P. 17) MAPPED THE AREA AS MOUNT SCOTT GRANITE, WITH A 180-FT INCLUSION OF SADDLE MOUNTAIN RHYOLITE IN THE NW-SW-NW-30. HE MAPPED TWO NW-TRENDING FAULTS IN THE NW OF 30.

Ore body information

  • Name UNNAMED
    General form VEINS

Controls for ore emplacement

  • Pegmatoid Veins Of Granite Through Gabbro

Comments on the geologic information

  • THE SADDLE MOUNTAIN RHYOLITE FLOWED UPON THE RAGGEDY MOUNTAIN GABBRO GROUP, AND THE MOUNT SCOTT GRANITE SILL INTRUDED BELOW THE RHYOLITE. PEGMATOID VEINS WERE FORMED IN THE LATE STAGES OF THE INTRUSION, AND TITANCLINOHUMITE WAS FORMED. THE COPPER PROBABLY CAME FROM SOLUTIONS ACTING UPON THE DIALLAGE GABBRO. THIS IS HIGH ENOUGH, IF WEATHERED, TO OCCUR IN EL RENO GROUP.
