Feldspar and Nepheline Syenite Potential in British Columbia
Feldspathic materials are used in the glass and ceramic industries as a source of alkalis, alumina and silica. These elements affect the rate and temperature of melting. fluidity of the melt and physical properties of the finished product. Silica, sodium, potassium and alumina ratios in the feldspar product vary for each industrial user, however, iron must be limited to less than 0. I per cent ...
متن کاملGeochemistry and petrogenesis of post-collisional ultrapotassic syenites and granites from southernmost Brazil: the Piquiri Syenite Massif.
The Piquiri Syenite Massif, southernmost Brazil, is part of the post-collisional magmatism related to the Neoproterozoic Brasiliano-Pan-African Orogenic Cycle. The massif is about 12 km in diameter and is composed of syenites, granites, monzonitic rocks and lamprophyres. Diopside-phlogopite, diopside-biotite-augite-calcic-amphibole, are the main ferro-magnesian paragenesis in the syenitic rocks...
متن کاملHaplosporidium nelsoni (MSX) epizootic in the Piscataqua River Estuary (Maine/New Hampshire, USA.).
A major epizootic of Haplosporidium nelsoni occurred during 1995 in the Piscataqua River Estuary, near the northern distributional limit of the parasite. Prevalence of H. nelsoni in samples of oysters, Crassostrea virginica, collected between 5 September and 18 December 1995 from sites in Maine and New Hampshire ranged from 15 to 81%, with up to 50% systemic infections. Associated proportions o...
متن کاملTiming of Syenite Intrusions on the Eastern Slope of the Sredinnyi Range, Kamchatka: Rate of Accretionary Structure Exhumation
The isotopic thermochronological study included the U–Pb (SHRIMP) and fission-track dating of zircon and fission-track and (U–Th)–He dating of apatite from syenite intrusions cropping out in the eastern slope of the Sredinnyi Range of Kamchatka. The emplacement time of the intrusion was determined, and its exhumation velocity was evaluated. According to U–Pb (SHRIMP) zircon dating, the age of s...
متن کاملFaults and their associated host rock deformation: Part I. Structure of small faults in a quartz–syenite body, southern Israel
We analyze pervasive and discontinuous deformation associated with small faults in a quartz–syenite body in southern Israel. The analysis includes detailed mapping, measurement of in-situ mechanical rock properties and microstructural study of the faults. The mapped faults have 1–100-m-long horizontal traces, consisting of linked, curved segments; the segmented nature of the faults is also appa...
