Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone.

contact us"Feldspar" is the name of a large group of rock-forming silicate minerals that make up over 50% of Earth''s crust. [1] They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar structures, chemical compositions, and physical properties.
contact usARL OPTIM''X, feldspar, sand, WDXRF, X-ray fluorescence Introduction The most common constituent of sand is silica (SiO2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness, is resistant to weathering. The composition of sand is highly variable, depending on the local rock sources and conditions.
