Potassium feldspar undergoes hydrolysis, which is a chemical reaction that breaks down the mineral into clay minerals like kaolinite, silica, and dissolved ions like potassium and bicarbonate. This process results in the decomposition of the feldspar and the formation of new clay minerals as a byproduct.
No, feldspar is not a sheet silicate. It belongs to the tectosilicate group, which forms a framework structure rather than sheets like those found in phyllosilicates.
Feldspar is found in North Carolina primarily in the Spruce Pine Mining District, which is located in the western part of the state. This area is known for producing high-quality feldspar, including both potassium feldspar and plagioclase feldspar. The feldspar from this region is used in various industries such as ceramics, glassmaking, and abrasives.
Granite rocks are generally odorless, as they are composed primarily of minerals like quartz, feldspar, and mica, which do not emit any significant scent. However, if granite is weathered or contains organic materials, it might have a faint earthy or mineral-like odor. Additionally, any smells associated with granite would likely come from surrounding soil or vegetation rather than the rock itself. Overall, granite is not known for having a distinct smell.

Feldspar does not have a distinct smell. It is a group of minerals commonly found in igneous and metamorphic rocks, known for their hardness and variety of colors.
Some feldspar crystals can be quite lustrous, like albite, but many, like microcline, are on the dull side. Feldspar cleaves well, into flat planes which can be quite lustrous, and will indeed reflect sunlight. It takes a nice polish, which will reflect even more light. Some varieties of feldspar, like moonstone or labradorite, interfere with the light, and display spectacular play of color.
Feldspar can be found in various states in the US, with major deposits located in states like North Carolina, Virginia, California, and South Dakota. Additionally, feldspar is also found in places like Maine, South Carolina, Idaho, and New Mexico.
Clay minerals form as a result of the chemical weathering of feldspar. Feldspar is broken down by water and carbon dioxide to form clay minerals like kaolinite, which are stable in Earth's surface conditions.

Arkose is a type of sandstone that contains more than 25% feldspar, along with quartz and other minerals like mica, magnetite, and hematite. The feldspar content gives arkose its distinct pinkish color.
