The Ingur alkaline granite massif and the associated Zr-Nb occurrence make up part of largest Mongolian-Trans-Baikal granitoid provinces. is composed arfvedsonite, biotite, alaskite granites. High content HREE determines low La/Yb n (2–7) value a negative europium anomaly (Eu/Eu*≈0.17). They are depleted in Ba, Sr enriched Nb, Ta, Zr, Hf Y. According to their geochemical properties rocks belong...

bibi maryam granitoid body with about 5 km2 has intruded into ophiolite mélange complex in sistan suture zone, in east of iran. thermal effects of this body on the host rocks show that this activity occurred after emplacement of ophiolite mélange. this intrusive body with general northwest – southeast trend is mainly tonalite-quartz diorite but there is a minor unit as dykes of granodiorite in ...

Apatite minerals of I-type Zouzan granitoids and typical garnet-bearing S-type granites have been analyzed by electron microprobe to define trace element concentrations and compare them in different granites. Zouzan granites are composed of apatites with lower Fe, Mn, Na and HREE and higher REE and ∑REE relative to S-type ones. Trace elements abundances of apatite often vary with some parameter...

Background: Pancreatic islet transplantation is one of the most promising strategies for treating patients with type I diabetes mellitus.Objective: We aimed to assess the immunoisolation properties of the multilayer encapsulated islets using alginate-chitosan-PEG for immunoprotection and insulin secretion from the encapsulated islets induced under differe...

Enrichment of free mica (i.e. as monomineralic grains) in the fine fraction of crushed rock aggregates affects the quality of the aggregate end product. Granitoid rock from the Svecofennian Province were used as being representative of crushed rock aggregates commonly used for construction purposes. The results reveal a general trend of enrichment of mica for finer fractions. For the coarse gra...
