Economic information

Geologic structures

Type of structure Regional
Structure description Principal Zone Of Pegmatites Trends Northeast; Most Pegmatites Strike Northeast, But A Few Strike Northwest.

Ore body information

  • General form LENTICULAR
    Strike N 15 TO 20 E
    Dip W

Controls for ore emplacement

  • Fractures, Dilation Zones (Cameron, 1951)

Comments on the geologic information

  • METASEDIMENTARY ROCKS ARE IN AN ADVANCED STAGE OF WEATHERING, AND PLAGIOCLASE IN THE PEGMATITE HAS BEEN KAOLINIZED TO A LARGE EXTENT. THE PEGMATITE SHOWS ZONING AS FOLLOWS: A BORDER ZONE COMPOSED OF FINE-GRAINED PLAGIOCLASE AND QUARTZ WITH SUBORDINATE PERTHITE AND ACCESSORY MUSCOVITE AND BIOTITE. THE WALL ZONE IS SIMILAR BUT MEDIUM- TO COARSE-GRAINED. AN INTERMEDIATE ZONE IS COMPRISED OF COARSE-GRAINED, PLAGIOCLASE-QUARTZ-PERTHITE PEGMATITE WITH STRIP MUSCOVITE AND BIOTITE, LOCALLY IN PARALLEL INTERGROWTH. NO OTHER ZONES WERE RECOGNIZED.

Economic information about the deposit and operations

  • Type Owner
    Owner Harris Clay Co.

Workings at the site

  • Type of workings Surface/Underground
    Overall length 167.64M
    Overall width 45.72M

Comments on the workings information

  • PIT IS AS MUCH AS 65 FEET DEEP. EXPLORATORY SHAFTS AS MUCH AS 75 FEET DEEP WERE SUNK IN THE FLOOR OF THE PIT, AS WELL AS A 20 FOOT ADIT AND APPENDED DRIFTS AND WINZE. NO COMMERCIAL-GRADE FELDSPAR WAS FOUND.

Comments on development

  • ECON.COM: PROSPECTING FAILED TO LOCATE A MINABLE BODY OF FELDSPAR, BUT MINABLE ZONES ARE EXPECTED TO OCCUR CONSIDERING THE SIZE OF THE PEGMATITE. PROSPECTING MAY HAVE FAILED TO REACH SUCH ZONES, OR THEY MAY HAVE BEEN REMOVED BY EROSION.
