Reflectance spectroscopy has been used to identify several deposit types. However, applications concerning lithium (Li)-pegmatites are still scarce. spectroscopic studies complemented by microscopic and geochemical were employed in the Fregeneda–Almendra (Spain–Portugal) pegmatite field analyze spectral behavior of Li-minerals lithologies. The similarity target class (Li-pegmatites) with other ...

Ebrahim-Attar granitic pegmatite, which is distributed in southwest Ghorveh, western Iran, strongly peraluminous and contains minor beryl crystals. Pale-green to white grains are crystallized the rim central parts of granite body. The characterized by low contents alkali oxides (Na2O = 0.24–0.41 wt.%, K2O 0.05–0.17 Li2O 0.03–0.04 Cs2O 0.01–0.03 wt.%) high Be2O oxide (10.0 11.9 wt.%). elements (...

Lithium (Li) was recently added to the list of critical raw materials by European Union due its significance for green energy transition. Thus, development new toolchains make Li exploration more economic and effective is needed. Stream sediment analysis can play an important part in these tool chains. In this work, two historical stream datasets covering parts Fregeneda-Almendra pegmatite fiel...

Lithium (Li) has grown to be a strategic key metal due the enormous demand for development of new energy industries over world. As one most significant sources Li resources, pegmatite-type deposits hold large share mining market. In recent years, several and super-large spodumene (Spd)-rich pegmatite have been discovered successively in Hoh-Xil–Songpan-Garzê (HXSG) orogenic belt northern Tibeta...

Replenishment of mineral resources, especially gold and rare metals, is critical for progress in the mining metallurgical industry Eastern Kazakhstan. To substantiate scientific background exploration, we study microinclusions minerals from rare-metal fields, as well trace-element patterns ores their hosts that may mark mineralization. The revealed compositions gold-bearing sulfide a number typ...
