Comments on the geologic information

  • THE DEPOSIT IS NEAR THE MT. STUART BATHOLITH. THE INGALLS TECTONIC COMPLEX IS A DISRUPTED OPHIOLITE
  • Tectonic Setting: The Jurassic Ingalls Complex, The Host Rocks Of The Blewett Camp Deposits, Is A Disrupted, Late Jurassic Ophiolite Complex. Igneous Acitivty In The Area Includes The Late Cretaceous Mount Stuart Batholith And Intrusive Rocks Of Early Magmatic Activity Of The Cascades Magmatic Arc (Miller, 1985, P. 27; Tabor And Others, 1982, P. 5-6).
  • Ore Control: Where The Veins Cut Gneissic Rocks, The Gangue Is Chiefly Quartz With Minor Amounts Of Calcite, But Where The Veins Cut Serpentinite, The Amount Of Calite Increases Relative To Quartz. The Most Productive Veins Are In Culver Gulch And Trend N75w. The Ore Is Generally Of Low Grade. Most Production Was From High-Grade Ore Shoots (Huntting, 1943, P. 8).
  • MOST OF THE MINERALIZATION OF THE BLEWETT CAMP IS IN VEINS CUTTING SERPENTINITE OF THE INGALLS COMPLEX (HAWKINS FORMATION IN WEAVER, 1911, P. 31-34). OTHER VEINS ARE IN METASEDIMATARY AND METVOLCANIC ROCK OF THE COMPLEX; HOWEVERE, VEINS IN THE SERPENTINITE ARE GENERALLY MORE PRODUCTIVE THAN THOSE IN THE OTHER ROCKS (WEAVER, 1911, P. 29-33).

General comments

Subject category Comment text
Deposit 3 PARALLEL VEINS. ORE IS GENERALLY LOW GRADE; MOST OF PRODUCTION CAME FROM HIGH-GRADE SHOOTS. BECAUSE OF TECTONIC SETTING AND HOST ROCK TYPES, IT IS POSSIBLE THAT THERE ARE OVERLAPPING DEPOSIT TYPES IN THIS DEPOSIT, PARTICULARLY SILICA-CARBONATE HG, WHICH IS COMMON IN OPHIOLITIC TERRANES
Deposit MRDS RECORD D001419 HAS BEEN MERGED WITH THIS RECORD AND DELETED
