Chemical weathering takes place mainly at the surface of rocks and minerals, leading to disappearance of certain minerals and formation of new products and secondary minerals For example, feldspar undergoes chemical weathering and it results in the formation of clay minerals ,
One of the commonest processes of clay formation is the chemical decomposition of feldspar feldspar or felspar, an abundant group of rock-forming minerals which constitute 60% of the earth's crust Chemically the feldspars are silicates of aluminum, containing sodium, potassium, iron, calcium, or barium or combinations of these elements.
Oct 16, 2019· In the Earth, one of feldspar's important roles is in clay formation; as the material weathers, it turns into clays Humans use it in pottery and glassmaking, and it is also added to scouring powders and used as a filler in a wide range of products Some are quite attractive, leading people to use them as semi-precious gemstones, as they can polish up quite nicely, and feldspar is also used to .
Such clay minerals formed after sediment deposition, most likely during shallow diagenetic processes (feldspar dissolution) associated with meteoric water circulation Surprisingly, within fault zones the same clay minerals are absent or are present in amounts which are significantly lower than those in the undeformed sandstone
Jun 16, 2015· Mineralogical analysis confirmed that biogenic plagioclase (Na–Ca feldspar) and illite were formed after bioreduction Our work shows that the interaction between alkaliphile and iron-bearing smectite could account for low-temperature feldspar and illite formation and these minerals may be used as biosignatures in sedimentary rocks
