Feldspar, a ubiquitous naturally occurring aluminosilicate, consists of many defects and impurities; some of these transform into metastable states by capturing electrons or holes, when exposed to ionizing radiation. These metastable states can have lifetimes of millions of years rendering feldspar useful for luminescence geochronology.

this thesis, the use of contracts in a functional embedded domain speci c lan-guage (Feldspar) is explored, building on work on contract checking for Haskell by Hinze, Jeuring et al. [2]. Contract checking of functions' properties can be done statically or dynamically. Static checking focuses on checking all limited speci cations. This method de-
Feldspar is an domain-specific language for digital signal processing and high-performance computations. The language is embedded as a library in Haskell. The front end supports common functional programming idioms such as map and fold, and the back end produces high-performance C code.

Globally, the long-term weathering process of basalts offers a sink for CO 2, effectively sequestering CO 2 from the atmosphere. Berner (1992), Drever et al. (1994), and Nelson et al. (2013), demonstrated this via chemical reactions by which this greenhouse gas is removed from the atmosphere. Even though more than four times as much CO 2
1. Introduction. Due to the unsurpassed mechanical properties of partially stabilized zirconia, its introduction to the dental market, almost a decade ago, considerably expanded the range of applications of ceramics in dentistry, a field where they are classically in demand due to their chemical inertness and a wide combination of optical properties, allowing excellent …
Abstract. Landau theory provides the basis for a unified thermodynamic treatment of structural phase transitions in minerals. It has recently been used, with effect, to describe the excess thermodynamic properties due to displacive and A l /Si ordering transitions in feldspars by Salje and coworkers. Semi-flexible T-O-T bonds (T = A l, Si) in the framework of the feldspar …

What is Feldspar? Feldspar is by far the most abundant group of minerals in the earth's crust, forming about 60% of terrestrial rocks. Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars. Feldspars are primarily used in industrial applications for their alumina and alkali content.
petrol. The state is rich in calcite, gypsum, manganese, lignite, bauxite, limestone, agate, feldspar and quartz sand and successful mining of these minerals is done in their specified areas. Gujarat produces DERXW RI,QGLD¶VUHTXLUHGDPRXQWRI soda ash and gives the country about 66% of its national requirement of salt.
processing cost is then equal to the value of the resulting mineral after processing minus the sales cost. Finding the OCOG is a bit more complicated because first, the opportunity cost of maintaining unexploited reserves has to be calculated, and then added to the processing cost. However, this value will automatically optimize the NPV and IRR.
The LA-ICP-MS analyses of feldspar are more susceptible to the inclusion of errant glass in sub-surface melt inclusions due to the much larger spot size for LA-ICP-MS compared to EMP beam. Glass inclusions in feldspar …
The Nossa Senhora do Carmo mining company, located at the southern of Santa Catarina (SC), Brazil, explores a large amount of feldspar to the ceramic market. As a result, waste is inevitable in the production and processing of the feldspar …
Shock metamorphism, caused by hypervelocity impact, is a poorly understood process in feldspar. This thesis addresses: a) developing a quantitative scale of shock deformation in plagioclase feldspar; b) expanding the utility of plagioclase feldspar for determining shock level; and c) micro-X-ray diffraction as a technique with which to study shock in feldspar. Andesine …
This paper aims to characterize and interpret the trends in reserves, resources, and mine production of feldspar and feldspathoid rocks during 2005–2019 in the Czech Republic. With over 101 Mt of total resources and 22 Mt of reserves, feldspar belongs to the crucial industrial minerals of the Czech Republic. With annual outputs of approximately 400–450 kt of …

Mount Mica is a poorly zoned sodic LCT-type pegmatite consisting dominantly of quartz, albite and muscovite in the outer portions. Potassium feldspar and lepidolite are restricted to the core zone. Micas in the wall zone are chemically homogeneous, but abruptly evolve into higher Cs + Rb bearing lithian muscovites and lepidolites in the core zone. The abrupt increase of the Cs, …
In this thesis I will use the domain specific language Feldspar which is designed for digital signal processing with baseband telecommunication systems in mind. 2.2 Digital Signal Processing Digital signal processing (DSP) encompasses the analysis, representation, and modification of digital signals. The signals in DSP are represented as ...
1.2 Feldspar Minerals Feldspar group minerals are the most common group of minerals in the Earth's lithosphere. The group itself has over 20 recognized members (Table 1) with these minerals either falling under the Alkali-feldspar or Plagioclase-feldspar subheadings. Feldspars are tectosilicates and have a monoclinic or triclinic symmetry.

Process Description Unit 100 – Size Reduction of Ore The BFD of the overall process is shown in Figure 1. The PFD for Unit 100, shown in Figure 2, is designed to reduce 41.5 tons/hr of gold ore from a feed range of 2-5" to 160 microns.
A new language, Feldspar, is presented, enabling high-level and platform-independent description of digital signal processing (DSP) algorithms, based on a low-level, functional core language which has a relatively small semantic gap to machine-oriented languages like C.
