It depends on the type of feldspar you're wondering about. I'm only 100% sure on one K-spar (Orthoclase) and one end-member of Plagioclase.
Orthoclase (and probably the other K-feldspars as well - Microcline and Sanidine) weather to Illite, the most stable of the clay minerals:
Orthoclase + CO2 + H2O ---> Illite + [K+ + HCO3- + SiO2]aq
Albite (the Na-end-member of the plagioclase solid solution (Anorthite is the Ca-end-member, which may well weather in the same manner) weathers to Kaolinite:
Albite + CO2 + H2O ---> Kaolinite + [Na+ + HCO3- + SiO2]aq

What kind of weathering is feldspar mixing with water and producing clay minerals?
The process of feldspar mixing with water and producing clay minerals is an example of chemical weathering. In this case, the water chemically interacts with the feldspar minerals, causing them to break down and form clay minerals.
Is feldspar mixing with acidic groundwater and producing clay minerals chemical or weathering?
This process is an example of chemical weathering. The feldspar reacts with the acidic groundwater to form clay minerals through a chemical reaction, altering the mineral composition of the rock.
Which of the following processes is an example of chemical weathering?
Which of the following is an example of chemical weathering?
When acid rain breaks down rocks by reacting with their minerals what type of weathering would this be an example of?
This is an example of chemical weathering, as the acid rain is reacting chemically with the minerals in the rocks to break them down.
What type of weathering occurs when reactions dissolve the minerals in rock?
Chemical weathering occurs when reactions dissolve the minerals in rocks. This process occurs when minerals in the rock react with water, air, or other substances to break down the rock. One common example of this is the weathering of limestone through the dissolution of calcite by carbonic acid in rainwater.

Why does the color of granite never change?
The colour of granite does in fact change. For example it will change during the weathering process where feldspar minerals will change to clay minerals such as kaolinite. If the degree of weathering is high this can significantly alter the colour of the granite.

How can climate rates affect chemical weathering?
Humidity and temperature are the keys to chemical weathering (and to answer a previous poster, chemical weathering is a natural process, though human activity can affect it. Chemical weathering needs water, to act as a solvent and to transport corrosive ions so chemical weathering in arid climates, and in arctic climates (where water is frozen, and so not available) have little if any chemical weathering. Chemical processes are also (mostly) accelerated by higher temperature so the high humidity and high temperature of the tropics is the place where chemical weathering predominates . Contribution of humic acids from soils is also important, and the high rate of growth of plants in tropical climates is also a factor. While the solution of Limestones by acidified water is the most commonly quoted example, many minerals break down chemically, feldspar breaking down to clay minerals would be another important example.
Is carbonic acid in water an example of chemical weathering?
Yes, carbonic acid in water is an example of chemical weathering. When carbon dioxide dissolves in rainwater, it forms carbonic acid, which can react with minerals in rocks, causing them to break down over time. This process is a common form of chemical weathering that contributes to the erosion and shaping of Earth's surface.
What happens to the minerals in rocks as a result of chemical weathering?
During chemical weathering, minerals in rocks can undergo a process of decomposition and transformation. This occurs as water and atmospheric gases react with the minerals, causing them to dissolve or alter their chemical composition. For example, minerals rich in iron can oxidize and form rust, while silicate minerals can break down and release their constituent elements. Ultimately, this can lead to the formation of new minerals and the release of dissolved ions into water streams.
