A brief description of the geology of the Shingle Creek area southwest of Penticton B.C. together with a more detailed report on the mineralogy and petrology of the Shingle Creek Intrusion (granite porphyry) are given. The presence of flows and tuffs showing similar mineralogical features to the Shingle Creek: Intrusion suggest that this intrusion was shallow rather than deep-seated. Sanidine phenocrysts showing oscillatory zoning are described with a range in composition of from 40 to 70 percent orthoclase (based on a comparison of optical properties with those determined by Tuttle 1952). The zones often occur in pairs showing a gradation from an albite-rich inner zone to an orthoclase-rich outer gone, It is tentatively suggested here that pressure changes in the magma, by altering the liquidus - solidus relations, sight provide this reversed- zoning. Plagioclase phenocrysts from the intrusion show transitional to high temperature optics when compared with the results of Bowen and Tuttle 1950. Beta quartz phenocrysts showing rounded outlines and development of late halos are described, from evidence given it is suggested that these features are due to resorption of quartz in a magma chamber prior to intrusion, followed by late growth after intrusion and daring crystallization of the porphyry matrix, Petrographlc study of the largest dyke associated with the porphyritic intrusion has suggested that this dyke may have been intruded in several stages. / Arts, Faculty of / Geography, Department of / Graduate

Mineralization at Galore Creek consists mainly of disseminated chalcopyrite, bornite and pyrite. Biotite and orthoclase are the dominant alteration minerals with commonly associated anhydrite, garnet, apatite, calcite and magnetite. The mineralization occurs in altered syenites, metavolcanics and brecciated equivalents of these along the contacts of a complex of syenite porphyries which display many characteristics of epizonal intrusions. Exsolution textures of bornite and chalcopyrite indicate a minimum temperature of deposition of 475°C. This leads to the conclusion that the deposit formed at a relatively high temperature and a shallow depth and therefore may be classified as xenothermal. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

The Cache Creek Group in the type area is characterized by oceanic rocks such as radiolarian chert, fusulinid limestone and pillow basalt. Three divisions have been made in the Cache Creek Group in this study: 1) structurally lowest is the melange unit (which has been identified as a subduction complex); 2) an overlying greenstone unit; and 3) the Marble Canyon Formation. Emplacement of the Marble Canyon Formation and greenstone unit on the underlying melange unit is believed to have occurred in the Early to Mid-Jurassic along a shallow dipping thrust fault. This emplacement may have caused soft sediment deformation features in the Early to Mid-Jurassic Ashcroft Formation. Felsic volcanic rocks and associated tuffs and volcaniclastic sediments are found mainly along the east side of the Cache Creek Group. These felsic rocks have been called the Nicola(?) Group and based on lithological correlation are of probable Late Triassic age. The Nicola(?) Group is correlated both with the western belt of the Nicola Group as described by Preto (1977) and the Pavilion beds as described by Trettin (1961). Blocks of Nicola(?) Group tuffs have been found in the Cache Creek Group melange unit. This indicates that in Late Triassic time the Cache Creek Group and Nicola(?) Group were adjacent to one another. Paleoenvironmental and geochemical evidence indicate an ocean island or platform depositional environment for the Cache Creek Group. Tropical shallow seas covered most of these islands. Lack of continental sediments indicates that the Cache Creek Group was distant from any major land masses. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
