Distribution patterns, petrography, whole-rock and mineral chemistry, and shape and fabric data are described for the most representative basement lithologies occurring as clasts (granule to boulder grain-size class) from the 625 m deep CRP-2/2A drillcore. A major change in the distribution pattern of the clast types occurs at c. 310 mbsf, with granitoid-dominated clasts above and mainly doleri...

granitoid rocks of kaje area, northwest ferdows, with the composition of diorite, monzodiorite, monzonite, monzogranite, syenogranite and granite, with calk-alkaline and high potassium affinities, have trace and rare earth element geochemical characteristics similar to those from subduction zones, belonging to i-type granitoid rocks. most of these rocks are oxidized (magnetite series), while on...

the lower to middle miocene chenar granitoid stock, a part of central iranian volcanic belt, is intruded into eocene volcano-sedimentary complex in northwestern kerman in south central iran. the chenar granitoid stock consists mainly of coarse to medium grain granodiorite and monzogranite with subordinate tonalite and syenogranite. alkali granites as aplitic veins and quartz dioritic dykes freq...

Many of the late Paleozoic granitoid plutons of the southern Appalachians are composite bodies with coarsegrained amphibole + biotite and biotite varietal facies (Speer et al., 1980). From field relations, these facies appear closely related, and multiple intrusion or differentiation comes to mind as an explanation for the relationship. In the Liberty Hill pluton, the coarse-grained central amp...

LIBS analysis is efficient in the classification of mineral grains and prospecting Be Li granitoid rocks.

the shah-kuh granitoid has intruded in the triassic–jurassic, pelitic and psammitic low-grade metamorphic rocks of the ne lutblock, in central iran. cordierite porphyroblasts are common in the southern pelitic sediments, but are rare in the northern psammiticrocks, in the contact aureole. deformation fabrics in the contact aureole are well-preserved within the cordierite porphyroblasts. therela...

The Harachiyama Formation comprises Lower Cretaceous volcanic rocks, which are distributed in the eastern margin of Kitakami Mountains northeastern Japan. Whole-rock chemical analysis, U–Pb zircon dating and Hf isotope analysis were performed to constrain formation age magmatic origin was discussed. lava tuff samples from Omoto Tsukue areas supported island-arc rhyolitic rocks (SiO2 content > 7...

The emplacement of the Mesoproterozoic Götemar Pluton into Paleoproterozoic granitoid host rocks of the Transscandinavian Igneous Belt is re-examined by microfabric analysis, including cathodoluminescence microscopy. Field data on the pluton-host rock system are used to strengthen the model. The Götemar Pluton, situated on the Baltic Shield of SE Sweden, is a horizontally zoned tabular structur...
