Geologic structures

Type of structure Regional
Structure description Block-Faulted Mountains; Strongly Folded And Faulted Pal Rocks, Fractured Mes Volcanic Flows, Major N-S And Transverse Faults In Cen Which Were Channels For Intrusives
Type of structure Local
Structure description Area Affected By 3 Tectonic Events Between Ends Of Cret And Tert. Intense Fracturing, Differential Vertical Uplift Of Blocks. 3 Directions Of Faults Recognized: N. 30 Deg. W., E-W To Nnw, N. 45 Deg. E.

Ore body information

  • General form OVAL
    Dip 75 TO 90
    Length 1800M
    Width 800M

Controls for ore emplacement

  • "Principal Outcrop" Ressembles A Mantle Dome, Rocks Strike Nw, Dip 20 Deg. Ne. This Zone Of Weakness Was Route Of Access Of Hydrothermal Fluids Which Were Trapped Below Compact Capping. Structure Was Arched And Fractured Causing Release Of Pressure And Dissemination Of Minerals
