02/15/2017 - "The existence of broad peak near 510cm-1 and disappearance of other peaks of feldspar at 480 and 570cm-1 indicate the presence of maskelynite, which proposes that the peak shock pressure could reach 20GPa at certain locations. "
05/01/2020 - "Shocked quartz and feldspar grains commonly exhibit planar microstructures, such as planar fractures, planar deformation features, and possibly microtwins, which are considered to have formed by shock metamorphism. "
05/01/2020 - "Preferred orientation distribution of shock-induced planar microstructures in quartz and feldspar."
09/30/2013 - "It exhibits a delicate iron infill, neo-formation of troilite in pockets and shock veins and neo-formation of Na-feldspar formed at high temperature and fast quenching. "
10/29/1993 - "Grains of shock-metamorphosed quartz, feldspar, and zircon were found in the Crow Creek Member (upper Campanian) at a biostratigraphic level constrained by radiometric ages in the Pierre Shale of South Dakota that are consistent with the (40)Ar/(39)Ar age of 73.8 +/- 0.3 Ma for MIS reported herein."

09/01/2022 - "Transport of H2O into nearby plagioclase induces the formation of diagnostic eclogite facies assemblages of jadeite-zoisite-K-feldspar-quartz ± kyanite ± phengite that pervasively replace former cm-sized plagioclase without requiring the participation of free H2O. "
02/01/2022 - "According to the influence of the diagenesis of various diagenetic facies, theoretical pore structure models of the three diagenetic facies were established, in which the construction facies includes mainly dissolved feldspar pores and intergranular pores, the destruction facies includes clay residual intergranular pores and intergranular pores, and the cementation facies includes primarily residual intergranular pores. "
12/01/2021 - "Metamorphic peak conditions of 770-840 °C and 5.5-7 kbar were obtained for the mineral assemblage garnet-biotite-sillimanite-K-feldspar-quartz indicating medium-pressure granulite facies metamorphism."

09/01/1965 - "Effect of feldspar, mica and loess on development of experimental silicosis."
08/01/1964 - "[EFFECT OF FELDSPAR, MICA AND LOESS ON THE DEVELOPMENT OF EXPERIMENTAL SILICOSIS]."

01/01/1988 - "The major reaction seen in both the feldspar- and the novaculite-treated rats was a granulomatous inflammation with varying degrees of fibrosis associated with the granulomas. "
06/01/2022 - "All examined abutment materials exhibited a similar soft tissue response compared to titanium and histological data did not reveal early signs of elevated inflammation caused by PEEK- and feldspar-veneered zirconia abutments. "

09/21/2023 - "Samples from arc and intraplate settings are distinguished by feldspar and clinopyroxene fractions (determined by different crystallization sequences) which, together with glass, comprise 80-100% of most samples. "
06/08/2022 - "The first class comprises granodiorite and tonalite (I-type) and is ascribed to volcanic arc, whereas the second one includes alkali-feldspar granite, syenogranite, and albitized granite with high-K calc alkaline character, which is related to post-orogenic granites. "
