Geologic structures

Type of structure Local
Structure description Local Faults And Brecciation. Host Rocks Were Folded And Faulted In Tertiary

Ore body information

  • General form VEINS AND VEINLETS
    Thickness 3.05M

Comments on the geologic information

  • Tectonic Setting: Deltaic Deposits Of The Eocene Puget Sound Group Were Folded And Faulted During The Tertiary (Gard, 1968, P. 27-29). Mineralization Probably Took Place During Or Shortly After Deformation.
  • Ore Control: Cinnabar Occurs In Fractures And Breccia Along Fault Zones In Sandstone, Shale, And Siltstone Of The Puget Group. Mafic Rocks Intruded The Sediments, And All Were Subjected To Folding And Faulting Prior To Mineralization (Mackin, 1944, P. 8). The Shear Zone Has A Maximum Thickness Of 10 Ft.
  • THE SEDIMENTARY ROCKS OF THE PUGET GROUP CONTAIN COAL, AND FOSSILS SUGGEST BRACKISH WATER AND ESTUARINE DEPOSITIONAL CONDITIONS (MACKIN, 1944, P. 7).
