Despite the large variations in hydrothermal activity at many different time scales (daily, seasonal, and decadal), the large chemical databases acquired over the past two decades [e.g., Parry and Bowman, 1990; Ball et al., 1998, 2002, 2007, 2010; …
In 2013, four years before Hurricane Harvey, we randomly installed feldspar marker horizons (0.5 m 2; Cahoon and Turner 1989) in each plot (n = 4 marsh cells …
The limited knowledge we have about red algal genomes comes from the highly specialized extremophiles, Cyanidiophyceae. Here, we describe the first genome sequence from a mesophilic, unicellular red alga, Porphyridium purpureum. The 8,355 predicted genes in P. purpureum, hundreds of which are likely …
The effect of ball milling on filler particle size and surface area. The effect of ball milling for hours at 320 rpm in the presence of the inorganic grinding agent on the particle size of kaolin and feldspar is presented in Figure 1; it is compared with the untreated counterpart.It is clear that the average particle size for both minerals was reduced after milling from 495 to 35 μm for ...
Porcelain tiles are vitreous ceramic products made of clay (kaolin and ball clay), feldspar and sand. The industrial production of these tiles consists of milling and homogenization, uniaxial pressing at 40–50 MPa and fast firing at 1180–1220 °C [1,2].Porcelain tiles are known to have a high flexural strength of greater than 35 ± 2 MPa, and low water absorption (<0.5%) which makes them ...
International Minerals #25. Awesome rubellite crystal standing free and upright on white feldspar matrix. From a very small and limeted pocket found in 2015. The crystal is undamaged and measures 2.0 x 1.4 x 1.0 cm. The photos show studio light setup and colour in daylight. Superb aesthetics!
Traditional dry magnetic separation has poor separation efficiency for fine-grained materials, and combining airflow and a magnetic field may be one of the most effective means to improve it. Based on the pneumatic drum magnetic separator developed by our team, an improved pneumatic magnetic separator with a segmented flow field is proposed, which pushes materials to move along the …

The Alathar paleolake deposit lies as an inverted relief feature within an interdunal depression in the south-western portion of the Nefud Desert sand sea ().The sedimentary sequence comprises a ~1.8-m-thick deposit of sandy-silt diatomite (units 2 to 7) underlain by wind-blown sands (unit 1) (Fig. 3 and text S1).Two paleolake sections were recorded at the site and a composite section …
Putting it all together. The deflate compressor is given a great deal of flexibility as to how to compress the data. The programmer must deal with the problem of designing smart algorithms to make the right choices, but the compressor does have choices about how to compress data.. There are three modes of compression that the compressor has available:
Feldspars are aluminosilicates containing varying amounts of calcium, potassium, or sodium. In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering …
Glass Standards and Ceramic Standards. ASTM's glass and ceramic standards are instrumental in specifying, testing, and evaluating the chemical, physical, and mechanical properties of various materials and products made of glass, ceramic, or clay. These materials are fabricated for a variety of purposes including arts and aesthetics, foodware ...

A subgroup of the Feldspar Group, poor in calcium, and mostly rich in potassium.It is mostly used in petrology for the high temperature series from sanidine to high albite; the series is incomplete at low temperature, but normal albite, orthoclase and microcline are generally still included as alkali feldspars. Some workers (eg the Strunz classification) include barium feldspars (celsian and ...
