To ascertain the Early-to-Middle Jurassic tectonic setting in central Great Xing’an Range, this study investigated Early and Middle granitoids exposed Chaihe area Range based on isotopic chronology petrogeochemistry. The results of show that have emplacement ages 179–172 Ma. Moreover, are high-K calc-alkaline unfractionated I-type fractionated granitoids, respectively. magma sources both origin...

The paper is concerned with the hydrogeological appraisal of the proposed mining operations in theThar lignite field in Sindh, Pakistan. The Thar coalfield covers an area of approximately 9000km2 andcontains three lignite seams lying at depth of 130m to 250 m. In the Thar lignite field, the presence ofthree main aquifers induces pore pressure in the rock mass surrounding the lignite seams and m...

Abstract We provide laser ablation–multicollector–inductively coupled plasma–mass spectrometry (LA-MC-ICP-MS) and high-precision chemical abrasion–isotope dilution–thermal ionization mass (CA-ID-TIMS) U-Pb ages Hf isotopic compositions of zircons from the Red Bluff Granite Suite mafic dikes in Franklin Mountains El Paso, Texas, USA. Granitoids exposed were previously divided into five magmatic ...

Field evidences, petrographic features and geochemical studies show that the garnet-muscovite granitoids of Boland Parchin area are S-type and they have sharp contact with the host rocks (metamorphic rocks). Granitoids of Boland Parchin contain minerals such as quartz, K-feldspars, plagioclase, biotite and Al-rich minerals (such as muscovite and garnet). Chemical composition of K-feldspars, pla...

Mineralogical, geochemical and fluid inclusion studies reveal two favourable environments for the localisation of beryl mineralisations in the Precambrian rocks of Egypt: (1) emerald-schist; and (2) beryl-specialised granitoid associations. Emerald occurs within the mica schists and is typically confined to the Nugrus major shear zone. However, beryl associated with granitoids occurs in pegmati...

The Miocene magmatic intrusion in the Tavşanlı zone of the Kütahya-Bolkardağ Belt (KBB) in the northwestern region of Turkey is represented by the Eğrigöz granitoids. This paper studies the petrology and geochemistry of hydrothermal alterations associated with the vein-type Cu-Pb-Zn mineralization hosted by this pluton, focusing on the determination of the mass gains and losses of chemical comp...

The presence of heavy radioactive minerals in the studied granitoids from which Wadi sediments leads to study exposure emitted gamma rays terrestrial radionuclides, such as 238U, 232Th, and 40K. geological revealed that derived surrounding granitoids, syenogranite, alkali feldspar granite, quartz syenite. mineral analysis confirmed were enriched with minerals, uranothorite well monazite, zircon...

Previous investigations of granitoids in Sumatra were focused on age dating with minimum geochemistry composition analysis. The purpose this study is to define the classification intrusions central and explain rocks' correlation Southeast Asia tectonic activities. A polarizing microscope was used for petrography description while XRF ICP-MS applied measurements. According geochemistry, almost a...
