Late-stage porphyritic andesite, dacite, and quartz diorite dikes (Feldspar Porphyry of Clode et al., ) intrude all other rock types in the study area, with the exception of the tonalite porphyry intrusions at Batu Hijau.

Three conformable units of fine-grained quartz feldspar porphyry were mapped in the Berry River For mation, Warclub Group, Northwestern Ontario.

Cooper. The Shingle Creek porphyry is located kilometres west of Penticton, British Columbia on the Penticton Indian Reserve, adjacent to Shingle Creek. The porphyry consists of an irregularly-shaped lenticular stock (2 by 7 kilometres) concaved to the south with several large offshoot dikes at.
Large pink sanidine phenocrysts (up to centimetres long), variable coloured albite, clear to smoky quartz and chlorite altered biotite occur in a pale greenish-grey groundmass. The porphyry shows a strong similarlity to the Eocene other Coryell intrusions such as the Shingle Creek porphyry and the recently described Beaverdell porphyry.
K-feldspar megacrysts in granitoid plutons have been interpreted as either phenocrysts or porphyroblasts. Most of the microstructural, mineralogical and chemical evidence (e.g., shape, alignment, concentration, Ba content, zoning, inclusions, and twinning) favours a phenocryst by: Phenocrysts of clear glassy rounded quartz and white orthoclase feldspar are set in a fine-grained matrix.

The Mount Polley deposit in north-central British Columbia is a Cu-Au porphyry system related to alkaline magmatism. The deposit is composed of numerous discrete zones of Cu-Au mineralization related to bodies of hydrothermal breccia, including the Northeast zone which hosted a pre-mining proven and probable reserve of approximately 11 Mt of ore averaging % Cu and g/t Au.

Abstract. K-feldspar crystals >5 cm in greatest dimension are common in calc-alkaline granites and granodiorites worldwide. Such megacrysts are generally interpreted as having grown to large sizes early in a magma’s crystallization history while they were largely molten, owing to field relations such as megacryst alignment and megacryst-rich clusters and to crystallographic features such as Cited by: Feldspar-phyric porphyry.

Extremely Re-rich molybdenite occurs with pyrite in sodic–calcic, sodic–sericitic and sericitic-altered porphyritic stocks of granodioritic–tonalitic and granitic composition in the Sapes–Kirki–Esymi, Melitena and Maronia areas, northeastern Greece.

The Shingle Creek deposit is Km west of Penticton north of Yellow Lake on the Penticton Indian Reserve. The Minfile reference below describes it as. Porphyry is a volcanic rock composed of large, conspicuous crystals (phenocrysts) and a fine grained to glassy groundmass.
Since the term “porphyry” refers only to the texture of the rock and not to its composition, the expression “porphyritic rock” is often used.
The magmatic rocks are well developed and include Archean basicultrabasic rocks and granitoids, Proterozoic moyite, and Yanshanian quartz Yanshanian intermediate-acid intrusive rocks are closely associated with the mineralization, in which a large number of copper-molybdenum deposits had been produced (i.e., Changfagou, Tianhexing, and Ermi).
They are up to m in thickness and are characterised by a higher proportion of matrix (over 80%) in comparison with the granodiorite and quartz-diorite porphyry dykes. The tan matrix is mainly K-feldspar and quartz, with up to 20% phenocrysts of quartz, plagioclase, K-feldspar and biotite.
Flowerstone (Flower Feldspar) - $/pound Locality: Vancouver Island, British Columbia, Canada. This unusual material is known by rockhounds by the names Flowerstone and Flower Feldspar, which are quite descriptive of the material. This Feldspar Phenocryst in Basalt material might be referred to as Basalt Porphyry by geologists.

It consists of massive, light gray and beige coloured lava flows and less resistant tuff, having a combined thickess of to m.
The lava is characterized by rectangular feldspar phenocrysts (%). Chapter 4: Igneous Rocks Igneous rocks that contain substantial dark silicate minerals and calcium-rich plagioclase feldspar (but no quartz) are said to have a basaltic, or mafic, composition.
