Noghan granitoid intrusion is located at the NW of Boin- Miandasht and lies in the Sanandaj-Sirjan structural zone (SSZ). Based on field evidence and petrographic studies, the pluton is considered as two-mica granite that has been strongly affected by deformation and shows a good mylonitic foliation study area. The main minerals in the pluton are quartz, alkali feldspar (microcline and perthite...
Mard-abad calc-alkaline granite formed along the margin of active pull-apart or intra-continental plates, and it is post-collision granite type. Granophyric, perthitic and myrmekitic are main textures that could form from crystallization of hypersolvus source magma, which occurred under water vapor pressure of approximately 2 kb. During this study the temperature of formation of these granites ...
Abstract Anatolia is characterised by a complex geodynamic evolution, mirrored wide spectrum of magmatism. Here, we investigated the timing and geochemical/isotopic characters Miocene to Pliocene volcanism Sivas–Malatya Region (Central Eastern Anatolia), its relationships with local regional tectonics. Na-alkaline basaltic lavas were emplaced during middle at Sivas (16.7–13.1 Ma), in North, whi...
the lut block in eastern iran is a micro-continental block within the convergent orogen between the arabian, eurasian and indian plates. large areas of the north-central, eastern, and western lut block are covered by volcanic rocks of paleogene, neogene and quaternary age. peak volcanic activity took place in the north-central part of the lut block during the eocene, and then dramatically decr...
BACKGROUND Weight loss in patients with Alzheimer's disease (AD) is a common clinical manifestation that may have clinical significance. OBJECTIVES To evaluate if there is a difference between nutrition education and oral nutritional supplementation on nutritional status in patients with AD. METHODS A randomized, prospective 6-month study which enrolled 90 subjects with probable AD aged 65 ...
The plutonic complex in SE Jersey consists of a late Precambrian gabbro-diorite mass which has been intruded by several granites. The status of the diorites which, like the gabbros, often possess a layered structure, is not clear. New geochemical data, including rare earth and trace element analyses, suggest that acid-basic magma mixing was not responsible for the variety of intermediate rocks....
We present an algorithm for deriving a spatial-behavioral type system from a formal presentation of a computational calculus. Given a 2-monad Calc : Cat → Cat for the free calculus on a category of terms and rewrites and a 2-monad BoolAlg for the free Boolean algebra on a category, we get a 2-monad Form = BoolAlg + Calc for the free category of formulae and proofs. We also get the 2-monad BoolA...
The composition of Mars' crust records the planet's integrated geologic history and provides clues to its differentiation. Spacecraft and meteorite data now provide a global view of the chemistry of the igneous crust that can be used to assess this history. Surface rocks on Mars are dominantly tholeiitic basalts formed by extensive partial melting and are not highly weathered. Siliceous or calc...
