Natural radioactivity and rare earth elements in feldspar ...

Thirteen feldspar samples were collected from different locations in the Abu Dob area for measuring the natural radioactivity of (238)U, (232)Th and (40)K using an HPGe detector. The variation in concentration of radionuclides for the area under investigation can be classified into regions of high, medium and low natural radioactivity.

feldspar - Identification of specific feldspars | Britannica

feldspar - feldspar - Identification of specific feldspars: 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 ...

ON THE IDENTIFICATION OF FELDSPARS IN SOILS

Specific gravity concentration of feldspars in different fractions has already been used by RETGERS (1891), although the liquids he used at that time have now become obsolete. In specific gravity separation with liquids two aspects must be considered. The first deals with the shape and the size of separation vessels.

Feldspar - an overview | ScienceDirect Topics

Feldspars can be divided into two main groups, alkali feldspars, ranging in composition from KAlSi 3 O 8 to NaAlSi 3 O 8, and the plagioclases, ranging from NaAlSi 3 O 8 to CaAl 2 Si 2 O 8. Olivines, pyroxenes, and amphiboles are known as accessory minerals in soils and are found in the heavy specific gravity fractions.

Feldspar - Wikipedia

Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.

Feldspar minerals are some of the most abundant minerals within the Earth's crust and are a common component of rocks. Species that are rich in potassium (K) are called potassium feldspars. Orthoclase, Microcline (Amazonite), and Sanidine are potassium feldspars. Feldspars rich in sodium (Na) or calcium (Ca) are plagioclase feldspars.
