Boulders of garnetiferous gneisses from Davis Creek, Matakitaki, and from Snark Creek and Mistake Gully, south of Hokitika, were found to contain sillimanite. The gneisses were probably derived from thin layers interbedded in coarse-grained biotitequartzofeldspathic gneiss near the Alpine Fault. They are of two types: ilmenitegraphite-garnet-biotite gneiss, and rutile-sillimanite-garnet-biotite gneiss. The latter is isochemically similar to New Zealand Alpine feldspathic greywacke or Alpine feldspathic argillite. Low oxygen-pressure conditions during metamorphism are suggested by the chemical composition of the gneisses, specially in the graphite-bearing gneiss. The garnet in the gneiss differs from that found in the Alpine Schists, and the biotite is probably of the Ryoke-Abukuma type, i.e., the low-pressure type of regional metamorphism. The sillimanite-garnet-biotite gneisses do not represent the highest grade of the Alpine and Otago Schists, but are formed by an independent type of metamorphism; they were probably formed under P-T conditions of 500°c ana 6 kb. It is concluded that the gneisses are a low-pressure intermediate metamorphic group to the west of the Alpine Fault, and the Alpine, Otago, and Marlborough Schists are a high-pressure intermediate group to the east; together they form paired metamorphic belts in a manner similar to that postulated elsewhere in the Circum-Pacific Region.

“…Grain size also influences sandstone mineral compostion. According to Pettijohn (1963), silica content generally Gandera (1977), Al-Azzaby (1980), as well as this study have documented that Spencer Formation sandstone lithofacies are predominately arkose and lithic arkose (Folk's classification, 1974).…”

Spencer Formation Sandstones; From Corvallis, Benton County, to Henry Hagg Lake, Yamhill and Washington Counties, Oregon. APPROVED BY MEMBERS OF THE THESIS COMMITTEE:Ro v : t l a , ChairmanWithin the thesis study area Spencer Formation arkosic/arkosic lithic sandstone lithofacies of Narizian age crop out in a sinuous north-northwesterly band from the Corvallis area into the Henry Hagg Lake vicinity ten kilometers southwest of Forest Grove, Oregon.Twenty eight surface samples and eight sidewall cores from the DeShazer 13-22 natural gas exploration well, were analyzed petrographically for detrital framework mineral composition and their major oxide and rare earth element concentrations utilizing x-ray fluorescence spectrometry (XRF) and inductively coupled plasma emission spectrometry (ICP) analysis, respectively. Twelve samples representing both lithofacies areally within the five separate Spencer Formation study areas, and stratigraphically within the DeShazer 13-22 well were selected for plagioclase composition, heavy mineral separates and scanning electron microscopy (SEM) -energy dispersive spectrometry (EDS) studies. These combined studies showed that two distinct lithofacies or informal members are present within the Spencer Formation in the thesis study area, they are; 1) a lower arkosic sandstone member, and 2) an upper arkosic to lithic arkosic sandstone member.Petrographic analysis showed that the lower member contains more detrital grains of quartz and potassium feldspar, has two to three times more epidote, and contains more schist and quartzite rock fragments than
