introduction the area of this study is located near hamadan within the sanandaj - sirjan tectonic zone. in the hamadan area, consisting mainly of mesozoic plutonic and metamorphic rocks, aplites and pegmatites locally contain garnets.(baharifar et al., 2004, amidi and majidi, 1977; torkian, 1995. garnet-bearing schists and hornfelses in the area are products of regional metamorphism shown by sl...

Abstract The Wolfsberg lithium deposit in Austria is one of the largest Li-Cs-Ta pegmatite resources Europe. part Austroalpine Unit Pegmatite Province Eastern Alps that formed during high-temperature, low-pressure Permian extensional event and was subsequently overprinted by Cretaceous eclogite-facies metamorphism Alpine orogeny. two types distinguished at deposit, amphibolite hosted-(AHP) mica...

This paper reviews the literature on dyking as a mechanism of felsic magma extraction from a source and transport to shallower crustal levels, and review the recent literature suggesting a range of alternative mechanisms of magma migration in hot crustal zones which produce mesoscale pervasive granite sheet intrusions. Recent papers have strongly favoured dyking as the main mechanism controllin...

Solid – liquid – vapor fluid inclusions in spodumene in rare-element granitic pegmatites commonly contain one or more highbirefringence minerals. Optical examination and laser Raman spectroscopic analyses of over 500 crystal-rich fluid inclusions in spodumene from Bikita and Kamativi, Zimbabwe, and Bernic Lake (Tanco), Manitoba, indicate that the high-birefringence phase is zabuyelite (Li2CO3)....

The Reflejos de Mar Li-pegmatite, located in northwestern Argentina, is part of the Villismán pegmatite group, Ancasti District, Pampean Pegmatite Province. Four garnet crystals from outermost were analyzed by major and minor elements (SiO2, TiO2, Al2O3, Cr2O3, MgO, CaO, MnO, FeO) using electron microprobe. belongs to rare-element class, spodumene type, LCT (Li-Cs-Ta) petrogenetic family. Based...

The metamorphic reworking of mineralized pegmatites during orogenesis remains unclear, making the genesis and tectonomagmatic significance pegmatite mineralization obscure. This study demonstrates multiple utilities titanite geochemistry in establishing Caledonian evolution world’s largest intra-plutonic Nb-Y-F Paleoproterozoic host rocks Tysfjord, Northern Norway. A combination titanite-specif...
