The Alvand plutonic complex is composed of various plutonic rocks, mafic and felsic dikes (pegmatites and aplites). Pegmatites and aplites consist of quartz, feldspar, mica, tourmaline, garnet and allanite. Based on the mineralogycal compound, pegmatites can be divided into tourmaline-garnet-muscovite-bearing, aluminosilicate-bearing and tourmaline-bearing pegmatites and aplites are composed of...
Based on the field observations host rock of tourmaline nodules in the Dehgah and Sarsakhti area are acidic dikes (Aplite) and monzogranite respectively. In these areas, nodules composed of tourmaline, quartz, alkali-feldspar, but leuco minerals component in Dehgah nodule are less than Sarsakhti area. The negative anomaly of Eu, enrichment in the light REE (LREE), decrease of HREE, and fractio...
Metapelitic rocks in the Gasht area include micaschist, kyanite schist, andalusite schist, garnet schist, staurolite schist, cordierite schist and sillimanite schist. Tourmaline occurs as accessory mineral in all of these rock types. These schists are metamorphosed regionally and are affected by contact metamorpism subsequently. Based on the textural relations and the fact that CaO and TiO2 con...
The Novo Cruzeiro pegmatite field in Minas Gerais (Brazil), located between Téofilo Otoni and the Jequitinhonha River, belongs to areas of EBPP with tourmaline emerald occurrences. pegmatites show beside coloured tourmalines, Cr-rich black cogenetic Cr-bearing emerald. General crystallization conditions show, based on obtained data, important changes during final phase crystallisation which cau...
In Iran, the most important tin and tungsten mineralization has occurred in Shah-Kuh granitoid pluton (Lut Block, east of Iran), and Nezamabad area (Boroujerd granitoid complex, west of Iran), respectively. Both mineralizations are mainly accompanied by existence of quartz- tourmaline veins. Nezamabad veins- type tourmalines have dravite composition and have been formed in hydrothermal conditio...
Prior treatment exposure in patients with relapsed/refractory multiple myeloma may affect outcomes with subsequent therapies. We analyzed efficacy and safety according to prior treatment in the phase 3 TOURMALINE-MM1 study of ixazomib-lenalidomide-dexamethasone (ixazomib-Rd) versus placebo-Rd. Patients with relapsed/refractory multiple myeloma received ixazomib-Rd or placebo-Rd. Efficacy and sa...
Ten road cut samples collected from five lithological sections of Lokoja sandstone formation in the Middle Niger basin were investigated using integrated granulometric, petrographic and geochemical analyses. Results of grain size analysis; standard deviation and skewness which ranges from 0.08 to -0.05 and 0.59 to -0.07 respectively suggest very well sorted to moderately well sorted sediments. ...
