K-feldspar Sand Grain Rounding in Eolian and Subaqueous Transportation [PDF]

open access: yes, 2023
This project’s aim is to compare the rounding of K-feldspar grains in eolian and subaqueous conditions. It was hypothesized that K-feldspar grains in a subaqueous environment are cushioned enough by surrounding water to prevent the rounding observed in ...

Secondary K-feldspar at the Precambrian–Paleozoic unconformity, southwestern Ontario [PDF]

open access: yes, 1995
The Precambrian–Paleozoic boundary in the subsurface of southwestern Ontario commonly is characterized by secondary K-feldspar. In the weathered and altered Precambrian granitoid gneisses at the unconformity, secondary K-feldspar has replaced ...

The Effects of Aminium and Ammonium Cations on the Ice Nucleation Activity of K-Feldspar [PDF]

open access: yes, 2023
Mineral dust is one of the most abundant types of ice nucleating particles in the atmosphere. During atmospheric transport, mineral dust particles can become coated with inorganic and organic solutes, which can impact their ice nucleation activity ...

Fluid-rock interaction and dissolution of feldspar in the Upper Triassic Xujiahe tight sandstone, western Sichuan Basin, China

open access: yesOpen Geosciences, 2018
Secondary porosity in the Upper Triassic Xujiahe tight sandstone of the western Sichuan Basin is mainly the product of feldspar dissolution. In the Xu-4 Member, the upper reservoir of the Xujiahe Formation, feldspars are dissolved to a significant extent

ANALYSIS OF THE FACTORS AFFECTING THE GRINDABILITY OF K-FELDSPAR BY THE FULL FACTORIAL DESIGN

open access: yesEskişehir Osmangazi Üniversitesi Mühendislik ve Mimarlık Fakültesi Dergisi, 2022
This study's aim is to investigate the wet and dry grindability of K-feldspar in a narrow grain size range in a stirred ball mill. In the evaluation of the grinding process, a full factorial design was used to observe the effects of the selected ...

Effect of Potassium Feldspar and Vermicompost Combined with Silicate Dissolving Bacteria on Yield of Wheat Plant Under Sandy Soils Conditions [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering
Organic farming is an alternative to regular farming. It makes use of organic residues rather than using chemical fertilizers and pesticides. A Field experiment was carried out during 2022-2023 growing season in Salehia, Egypt.
