Geologic structures

Type of structure Regional
Structure description Northeast-Southwest, Columbia-Quantico Syncline

Ore body information

  • General form POD/LENS
    Strike N. 10-20 DEG. E.
    Dip *
    Thickness 3M
    Length 300M
    Depth to top 0M

Comments on the geologic information

  • FELSIC MATERIAL FOUND LESS THAN 1.5 KM FROM ORE BODY. PRESENCE OF TOURMALINE IN GANGUE SUGGESTS MAGNATIC ORIGIN. GREENSTONE VOLCANICS REPRESENT LOW GRADE METAMORPHOSIS OF ANDESITE FLOWS. ; MAJOR.UNITS: SCHIST ; GEOL.DESC: PYRITE PROBABLY REPLACED THE SCHIST. PYRITE FOLLOWS THE STRUCTURE OF THE ORIGINAL ROCKS, BUT IN SOME CASES HAS ITSELF BEEN FOLDED SUBSEQUENT TO FORMATION.
