In some types of chemical weathering the original mineral becomes altered to a different mineral. For example, feldspar is altered—by hydrolysis —to form clay minerals plus some ions in solution. In other cases the minerals dissolve completely, and their components go into solution. For example, calcite (CaCO 3) is soluble in acidic solutions.

Orthoclase is frequently known as potassium feldspar or K-spar, and is easily distinguished from the plagioclase feldspars in hand sample by its lack of striations. In thin section, alkali feldspar grains often look like they're sprinkled with dirt (PPL) or tiny confetti (XPL). You can find the explanation on the alkali feldspar page.

Sources of Feldspar. Historically, the most important source of moonstone has been Ceylon, where it is found in many areas as rolled, rounded pebbles in the gem gravels with spinel and corundum.

Feldspars are generally light-colored, including white, pink, tan, green, or gray. The color varies due to impurities within the crystal structure. Feldspar is the mineral that gives granite its pink, green or gray color. When feldspar weathers from igneous or metamorphic rocks, it can accumulate as sand.

Properties of Feldspar Chemical Properties ┗ Each type of feldspar has a different chemical formula, depending on its composition. The specific chemical formula for this group of compounds is KAlSi 3 O 8 – NaAlSi 3 O 8 – CaAl 2 Si 2 O 8. ┗ These minerals are chemically inert, and have a stable value of pH.

Calcite Group. Calcite-Rhodochrosite Series. A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varieties.

Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute; some plagioclase feldspars are not polysynthetically twinned.

What is Feldspar? Feldspar is by far the most abundant group of minerals in the earth's crust, forming about 60% of terrestrial rocks. Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars. Feldspars are primarily used in industrial applications for their alumina and alkali content.

The difference between crystal and similar gems | WillingWoods. The gems that are similar to crystals are mainly fluorite, calcite, feldspar, tourmaline, aquamarine, sageite, etc. The similarity is mainly reflected in appearance characteristics such as color and transparency. However, there are many differences between these gems and crystals.

Feldspar. Although feldspars are the most common minerals in igneous and metamorphic rocks, feldspars are less stable than quartz at conditions near the Earth's surface. Thus feldspars make up only 10-15% of all sandstones. Feldspars in sandstones consist of the following: Plagioclase - usually showing albite twinning.
