Structure: Breccia. Host Rocks Were Folded And Faulted In Tertiary
Tectonics: Cascade Volcanic Arc
Deposit: Ore present in fault breccia. A model has not yet been published for this type of deposit
Geology: GEOL.DESC: CINNABAR ALONG SEAMS IN FAULT BRECCIA 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 That Localizes Mineralization At The Barnum-Mcdonnell Deposit Has A Maximum Thickness Of 10 Ft. The Best Ore Is In Tuffaceous Sandstone (Huntting, 1956, P. 256). THE SEDIMENTARY ROCKS OF THE PUGET GROUP CONTAIN COAL, AND FOSSILS SUGGEST BRACKISH WATER AND ESTUARINE DEPOSITIONAL CONDITIONS (MACKIN, 1944, P. 7). AT THE LYTLE-LYNCH THE COUNTRY ROCKS ARE SHALE, SANDSTONE, COAL, AND PORPHYRY (HUNTTING, 1956, P. 265).
