Cathodoluminescence of Feldspar Minerals [PDF]
, 2012 A collection of North American feldspar minerals were examined using cold-cathode cathodoluminescence (CL) spectroscopy. The resulting spectra were fit and characteristic peaks were associated with each feldspar phase; these peaks are independent of ...

Meteoritics &Planetary Science, EarlyView.Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...

Thermal stability of infrared stimulated luminescence of sedimentary K-feldspar [PDF]
, 2011 The thermal stability of the infrared stimulated luminescence (IRSL) signal measured at 50 °C as a function of IR stimulation time was investigated using KF grains extracted from sediments from central China.

Sedimentology, EarlyView.ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Glass- and ceramic-grade feldspar from waste [PDF]
, 1996 In a typical feldspar operation extraction and size reduction may account for 20 to 25% of operating costs. Production of feldspar from feldspathic quarry fines and / or mine tailings would avoid this cost as the material has already been extracted and ...

Sedimentology, EarlyView.ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Water in Hydrothermal Feldspar [PDF]
, 2015 Color poster with text, photographs, charts, and graphs.Feldspar is the most common mineral in the Earth's crust, and although water is present in only trace amounts (~ hundreds of ppm), this quantity is sufficient to make crustal feldspar one of, if not

Contract Checking for Feldspar [PDF]
, 2012 "Contracts play an important role in the construction of robust software" [13]. Program invariants are expressed in familiar notation with known semantics by using contracts.

Terra Nova, EarlyView.ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Microtextural Studies of Feldspar in Ordinary Chondrites [PDF]
, 2018 Ordinary chondrites contain an important record of events that took place during the earliest period of solar system evolution. These include primary processes, such as chondrule formation, and secondary processes, those that affected asteroids after ...
