StructureAntler Belt. Major, Deep Seated, N-S Structural Zone (Suture) 40 Km (25 Miles) Long, Known As The Getchell High-Angle Fault System Bounds The Eastern Flank Of The Osgood Mountains. N-S Trending Belt Of Gold Mineralization That Is At Least 5.6 Km (3.5 Miles) Long And 300 M (1000 Ft) To 450m (1500ft) Wide., The Conelea Overturned Anticline Dominates The Structural Picture Of The Rabbit Creek Mine Area. The Fold Axis Strikes N20-30w, Dips 20-30 Degrees Southwest, And Plunges 5 Degrees Northwest. The Conelea Anticline Is Offset By Three Ne-Striking Faults; The Northernmost Of The Three (Dz Fault) Has About 2000 Ft. Of Dextral Offset. The Dz Fault Is Interpreted As A Riedel "R" Shear Associated With An Inferred Major Ns Basement Suture With Right Lateral Offset, The "Rabbit Suture".

Tectonic settingBack-Arc Thrust Belt

AlterationDecalicification, Silicification, Dolomitization, Argillization, And Minor Sericitization Of Sediments. Albitization And Propylitization Of Basalt. Decalcification Increased Porosity, Allowing Introduction Of Mineralizing Fluids. Silica Was Introduced In Several Stages In The Hgo Orebody. Dolomitization Accompanied One Of The Silicification Stages. Argillization Is Important In The Lgo Orebody.
