Geologic structures

Type of structure Regional
Structure description Late Paleozoic Sediments Were Deposited Along An Active Continental Margin.

Controls for ore emplacement

  • Sedimentary Rocks In A Roof Pendant Are Mineralized. Huntting (1956, P. 366) Suggests That The Prospect Is A Promising Zinc Deposit.

Comments on the geologic information

  • ARGILLITE AND GREENSTONE OF PROBABLE LATE PALEOZOIC AGE ARE INTRUDED BY DIKES OF THE PORPHYRITIC GRANODIORITE OF MANILIA CREEK (PARDEE, 1918; GULICK AND KOROSEC, 1990, GEOL. MAP).

Economic information about the deposit and operations

Comments on the production information

  • REPORTED TO HAVE PRODUCED, BUT THE AMOUNT IS UNKNOWN (HUNTTING, 1956, P. 366).
