The W–Sn Panasqueira ore deposit is a magmatic-hydrothermal system, which includes high-grade quartz-vein type mineralization and disseminated greisen-type occurring in the upper part of two-mica granite. We investigated genetic chronological relationships between greisenization granite formation ore-bearing quartz veins by monitoring major trace elements variations quartz-white mica assemblage...

It has previously been shown that granite workers with heavy exposure to silica had glomerular and proximal tubular dysfunction evidenced by increased urinary excretions of albumin, alpha-1-microglobulin (AMG), and beta-N-acetyl-glucosaminidase (NAG). The investigation was replicated in another group of granite workers to further elucidate the exposure effect relation. The urinary excretion of ...

‘I fact, just about everything that was taught as recently as ten years ago about granitic magmatism has been turned on its head.’1 So concludes John Clemens in his overview paper about the origin of granite, published in the UK in the Proceedings of the Geologists’ Association. In his introduction to Clemens’s paper and the accompanying discussion, editorial board member W.J. French explains t...

The Zhangbaoshan (ZBS) super-large Rubidium deposit, located in the Eastern Tianshan, is a typical granite-type Rb deposit. ZBS deposit mainly hosted highly evolved Baishitouquan (BST) pluton enriched F and Rb, which exhibits five lithological zones from bottom to top: leucogranite (zone-a), amazonite-bearing granite (zone-b), amazonite (zone-c), topaz-bearing (zone-d) topaz albite (zone-e), as...

The Askartor Be-Mo deposit is located in the southeastern area of Chinese Altay orogenic belt Xinjiang, NW China. Zircon U-Pb data show that there are two periods magmatic activities ore district, namely, Devonian granodiorite (386.8 ± 2.6 Ma) and biotite granite (385.4 4.4 Ma), Triassic two-mica (247.5 2.2 muscovite (231.4 2.0 Ma). zircon age pegmatoid orebody 220.6 1.6 Ma which coincides with...

Immunoglobulin concentrations and lymphocyte counts were determined in bronchoalveolar fluid obtained from nine symptomless, healthy, non-smoking granite workers (mean age 45.6, range 22-56 years) and nine normal, non-smoking, non industrial controls (mean age 22.8, range 21-32 years). The proteins were measured in unconcentrated lavage fluid by means of a solid phase, enzyme linked immunosorbe...

CDF and Granite: A Comparison Master's Project Report Lorna Ellis May 2004 Abstract Because large scientific datasets are often stored in files, efficient data analysis depends on efficient I/O and data manipulation tools. The Granite Scientific Database System is a system that incorporates database methodology and spatial semantics to support retrieval and visualization of scientific data. CDF...

In this study, production possibility of glass and glass-ceramic produced from granite was investigated. The composition of granite based glass bath mixture was 50 wt% granite, 25 wt% dolomite and 25 wt% sodium carbonate. Composition that was grounded and mixed in a ball mill for 2 h was melted at 1500 ◦C for 1 h. Glass samples were heat treated for crystallization to produce glass-ceramic mate...

Pecoits et al. (Reports, 29 June 2012, p. 1693) describe bilaterian trace fossils and assign them an Ediacaran age based on the age of a granite interpreted as intrusive. We argue that the granite is not intrusive but in fact represents the basement of the sedimentary succession. Moreover, we show that identical trace fossils occur in nearby Carboniferous-Permian glacigenic rocks.
