Upper Cretaceous intrusives of limited extent crop out in the Coastal Cordillera near Valdivia (39º48’ S), 100 km west main topographic divide Andean Cordillera. Given that plutonic rocks same age at latitudes high Andes coastal emplaced a forearc position upper plate subduction setting. They correspond to hypabyssal displaying mainly porphyritic texture and lithological variations with microto...
This study aims to account for the petrogenesis and mineralization of pegmatites around Wowyen area, northcentral basement complex,Nigeria. Field studies, petrography whole rock geochemistry (Major oxides were estimated by X-Ray Fluorescence while trace elements Inductively Coupled Plasma Mass Spectrometry) where methods adopted. The area are emplaced in remobilized belt Nigerian Basement compl...
The basement rocks encountered in exploratory boreholes drilled for exploration and evaluation of coal deposits in Thar Parkar district, Sindh Pakistan have formed the basis for present studies. The basement complex was penetrated through eighteen boreholes at drill depth range from 112 to 279 meters. These rocks were identified in field as Pink and Grey Granites.. The basement rocks are of Ign...
East misho granitoid intrusion body, a part of Alborz-Azarbaijan zone, is located about 60 Km north west of Tabriz, NW Iran. This pluton with an area of about 50 km2 has cut percamberian unmetamorpic sedimentary rocks and, is covered with Permian sedimentary rocks with igneous nonconformity. Litological composition of the studied pluton displays a range of alkali granite, monzogranite and syeno...
Heris intrusive body has cut Kahar Formation and has been covered by Permian basal sediments, non-conformably. The composition of this body is granite- alkali granite with metaluminous to weak peraluminous nature. The strong negative anomaly of Eu in REE diagram indicates the presence of plagioclase in the source area or differentiation of it during evolution of the magma. Negative anomaly of B...
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...
How and at which thermal conditions the convergence between Chinese Altai East Junggar operated remain poorly understood. This issue is addressed in current study by focusing on timing petrogenesis of syntectonic granite dykes from representative areas Fuyun (convergent front) Kalasu-Aletai (Chinese interior). It shown that are fractionated I- S-type granites, with zircon monazite U-Pb ages 300...
La Unión pluton (LUP) belongs to the metamorphic and igneous Sula Terrane (ST) of Central Guatemala, limited north by Motagua fault (MF) south Jocotán-Chamelecón system (J-CH-FS). The basement ST is characterized high-grade rocks belonging Las Ovejas Complex extensive low-grade San Diego phyllite, latter in tectonic contact with LUP. A combination field data, petrographic geochemical analyses a...
Background: Neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and platelet-lymphocyte ratio (PLR) have a prognostic value in several types of diseases such as cancers and they vary in different races. So, we aimed to evaluate the normal range of these markers among healthy people to determine the normal value in Iranian population. Methods: In the present study, cross-sectiona...
