“…Alkaline metavolcanic rocks and granitoid intrusions occur in the vicinity of the discussed pegmatite sites [20][21][22]. This is the case in the Kaustinen and Kolmozero areas, where numerous pegmatite veins can be found in these rocks [23][24][25][26]. In the Kaustinen area (Finland) and the Kolmozero area, there are pegmatite veins with lithium-cesium-tantalum mineralization (LCT), which are up to several meters thick and 100 m or more in length.…”

Li-Ce-Ta (LCT) pegmatites containing lithium mineralization in the form of spodumene and lepidolite, as well as fuchsite, from the regions of northern Scandinavia (N Norway, N Finland, N Russia) were studied. Detailed analyses of the chemical compositions of these minerals were carried out, involving scanning electron microscopy (SEM) with energy-dispersive spectroscopy (EDS), Fourier transform infrared (FTIR) spectroscopy with attenuated total reflectance (ATR), and X-ray photoelectron spectroscopy (XPS) studies. Their crystal structures were confirmed with the X-ray diffraction technique. Studies involving microscopy were also carried out, indicating the optical features of these minerals. Based on the analyses carried out in the studied rocks, the characteristics of these minerals were determined, as well as the crystallization conditions. This research indicates that the N Scandinavian area is prospective and may lead to further discoveries of this type of pegmatite in the studied region.

“…Microperthitic textures in crystals are visible using a light microscope, whereas cryptoperthitic textures can only be seen with an electron microscope. The alkali and alumina content of feldspars makes them industrially useful (Brown et al, 2017;Makinde and Makanjuola, 2019;Morozova, 2020;Bhattacharya et al, 2020). Alumina in feldspar provides hardness, workability, strength, and makes glass resistant to chemicals.…”

The pegmatite in the Dagbala area, southwestern Nigeria occurs as a dyke trending in a NW-SE direction which intrudes the Hornblende-Biotite-Granite. Geochemical, petrological, and mineralogical analyses were carried out on four (4) pegmatite samples obtained from the study area to determine the feldspar quality and the results were compared with commercial ceramic and glass grade to determine its suitability in ceramics and glass production. From the results, SiO2 ranges from 74.97% to 72.06%, Al2O3 ranges from 15.16% to 15.05%, Fe2O3 ranges from 0.45% to 0.31%, Na2O ranges from 5.56% to 2.76%, K2O ranges from 8.42% to 3.53% and CaO ranges from 0.72% to 0.09% respectively. After comparing the results with the commercial ceramic grade and glass grade, it shows that they can be used as raw materials in the ceramic and glass industry. However, minor pre-treatment processes are required, such as magnetic separation, to reduce the Fe2O3 content and froth floatation to reduce the K2O content in ceramic production. In glass production, magnetic separation should also be carried out to reduce the Fe2O3 content and froth floatation should be carried out to reduce the K2O content. Additives should be added to increase the amount of CaO, Al2O3, and Na2O present.
