Abstract Pelites (shales and mudstones) are arguably the most important rock type for interpreting metamorphism. Their significance derives from their widespread occurrence range of mineral assemblages they develop at different conditions pressure temperature. We compiled a global database 5729 major-element whole-rock analyses pelites metamorphic grades to granulite-facies paragneisses) (1) de...

This paper presents a mineralogical and chemical investigation of shale deposits from the U.S. Gulf coast in order to document the mechanisms and reactions involved in the diagenetic conversion of smectite into illite. Cuttings from the 1,250 to 5,500 m stratigraphic interval of a well were sorted by grain size and analzyed by x-ray diffraction to assess chemical and mineralogical trends with d...

The study area is located around Pazarc?k - Narl?, Kahramanmara? province. aim of the to investigate value units belonging Yenicekale Formation K??la Marl Member as cement raw material. As a result XRD studies, it was determined that formation Marn which exposed large areas in region composed illite, quartz, dolomite, calcite and chlorite minerals by rock analyzed. By geochemical analysis, SiO2...

The accumulated knowledge about the structure of a substance makes it possible to control its properties, including purposeful selection raw materials and for creation, vice versa, based on natural or artificial material composition, predict physical chemical properties. This approach allows choosing replacement rare even scarce types mineral produce particular product. analysis literature data...

The combination of specific mechanical, esthetic, and chemical properties is decisive for the application of materials in prosthodontics. Controlled twofold crystallization provides a powerful tool to produce special property combinations for glass-ceramic materials. The present study outlines the potential of precipitating Ca5(PO4)3F as well as Sr5(PO4)3F as minor crystal phases in Li2Si2O5 gl...

Th e response of diff erent fertilizer doses was studied on the ratoon crop as well as main crop. Th e diff erent fertilizer doses under the study were F1 (N=90, P2O5 = 45, K2O=50, S=13, Zn = 4: in kg ha-1), F2 (N=105, P2O5 = 55, K2O=60, S=13, Zn = 4: in kg ha-1), F3 (N=120, P2O5 = 65, K2O=70, S=13, Zn = 4: in kg ha-1), F 4(N =135, P2O5 =75, K2O=80, S=13, Zn=4: in kg ha-1) and F5 (N=150, P2O5 =...
