10 Stuut, 2014). The feldspar minerals can be grouped according to bulk composition into potassium rich feldspar (Kfeldspar) and Na, Carich species (plagioclase). While theseries of plagioclase contains all fractions of Na, Ca, there is a mixing gap for Kfeldspar. Only a limited fraction of K+ can be replaced by Na+ or Ca2+. Kfeldspar is ...

the other hand, the alteration processes of Kfeldspar from the view point of thermodynamics have been reported (Lagache et a11961a, 1961b; Lagache 1965; Helgeson et a11969, 1984). However, alteration prod ucts of Kfeldspar, especially at the initial alteration stage, and formation processes of the products have

Earlystage alteration is dominated by potassic alteration with extensive secondary biotite, Kfeldspar and magnetite. The alteration zone includes dense magnetite and quartzmagnetite veinlets, in which CuFebearing sulfides are present. Propylitic alteration occurs in the host basic volcanic rocks. Extensive chloritizationsilicification ...
Meteorites that produce Kfeldsparrich ejecta blankets correspond to mass extinctions. Journal of the Geological Society, 2021; jgs DOI: /jgs Cite This Page :
The lateMesoproterozoic granitoids, which were discovered for the first time in the Solwezi Dome of the Lufilian Arc, can provide pivotal constraints on the provenance of detrital materials in the Neoproterozoic Katanga Supergroup and the reconstruction of the Mesoproterozoic continent. We report here UPb zircon ages, geochemical and SrNdHf isotopic data for the gneissic Kfeldspar ...
KFeldspar alteration. KFeldspar is one of the most abundant hydrothermal minerals in potassically altered rocks, and typically replaces plagioclase phenocrysts and groundmass phases. KFeldspar has mostly irregular crystal shapes with serrate or wavy margins. KFeldspar also occurs as selvages around anhydrite veinlets (Fig. 4a) as well as ...

Rare earth element (REE) fractionation trends in feldspars are reported from Olympic Dam (including Wirrda Well and Phillip's Ridge) and Cape Donington (Port Lincoln), for comparison with two other igneoushydrothermal terranes within the eastern Gawler Craton: MoontaWallaroo and Hillside. The case studies were selected as they represent ~ 1590 Ma Hiltaba Suite and/or ~ 1845 − 1810 Ma ...
The quartz:Kfeldspar ratios ranged from to (Table 1), except for sample RC1 (ratio of 31). RC1 had an exceptionally high quartz:Kfeldspar ratio due to its large concentration of quartz (85%) (Table 1). Similar quartz:Kfeldspar ratios were observed for the DJP loess and the deserts to the north and west of the CLP (Figure 3).
Sanidine (K, Na) (AlSi 3 O 8) is the monoclinic hightemperature alkaline KNa feldspar, which usually contains about 30%, but sometimes up to 62% sodium (Ab) component. It is found only in young volcanic discharges or volcanic rocks (rhyolite, trachyte, and dacite).
Feldspars are hard minerals, all of them with a hardness of 6 on the Mohs scale. This lies between the hardness of a steel knife () and the hardness of quartz (7). In fact, feldspar is the standard for hardness 6 in the Mohs scale. Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff.
The relation between the mineralogical characteristics of size selected feldspar particles from 50800nm and their ability to act as ice nucleating particles (INPs) in the immersion mode is ...
Feldspar Mineral Composition, Uses, Types: All the rockforming feldspars are aluminosilicate minerals with the general formula AT4O8 in which A = potassium, sodium, or calcium (Ca); and T = silicon (Si) and aluminum (Al), with a Si:Al ratio ranging from 3:1 to 1:1. Microcline and orthoclase are potassium feldspars (KAlSi3O8), usually designated Or in discussions involving their endmember ...
The albitization of Kfeldspar is a common diagenetic process that has thus far received little attention and is not fully understood in finegrained sedimentary rocks. To better understand the albitization of Kfeldspar, studies in organic and siltrich finegrained rocks of the lower Cambrian Qiongzhusi Formation in the southwestern Upper Yangtze region, China, were carried out via Xray ...
However, the application of Kfeldspar IRSL dating has long been hampered by a phenomenon called anomalous fading [16,17,18]. The thermally stable luminescence signal of Kfeldspar fades under ambient temperature, which is suggested to be a result of quantum tunneling between the electron traps and holes [16,17,18,19].

Many Kfeldspar megacrysts are found in the MEs, which provide evidence of the physical mixing of mafic and felsic magmas. It is likely that some zircons in MEs may be xenocrystic from the host PQS. CL images show that the majority of zircon grains from the FG (Sample 12TK16) are dark and prismatic with a banded structure (Fig. S1).
The Yangtze River is the largest river in Asia and its age and evolution has been the subject of debate for more than one century. Here, we applied a combination of detrital muscovite and Kfeldspar 40 Ar/ 39 Ar dating on a set of samples from late Cenozoic Nanjing fluvial gravel sediments (overlain by basalt with ages of ∼ and ∼ Ma) distributed along the lower Yangtze River to ...
