The Shaku–dake body represents a two–pyroxene diorite (TPD) located in the Northern Kyushu region southwest Japan and is member of Cretaceous batholith. Layered structures feeder dikes wall TPD are recognized as magma plumbing systems that result from pulses. pulses were likely provided localized anomalous spots, which have been horizontal variations modal, major, trace element compositions bod...
The study area is located in North-East of Lut block, and in Basiran Geological Quadrangle Map (1:100000).Tertiary intrusive-subvolcanic rocks intruded Paleocene limestone and formed skarn and Iron mineralization. Petographic studies show that rocks are Hbl-diorite porphyry, Hbl-qtz- diorite porphyry, Px- diorite porphyry, Hbl-px- diorite porphyry, Hbl-diorite and Bt-diorite. These rocks are s...
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 bedrock used for underground construction has obvious traces of hydrodynamic scouring damage, and the mechanical properties especially are severely damaged under a groundwater environment. On this basis, considering excavated various saturations, uniaxial compression test diorite is carried out. Meanwhile, scanning electron microscopy (SEM), energy spectroscopy (EDS) X-ray diffraction (XRD)...
The Kaleybar intrusion with an area of 750 km2 is located in the north east Azerbaijan, NW Iran. Based on structural subdivisions of Iran, it is located in the West Alborz-Azerbaijan Zone wich is intruded into the Azerbaijan continental crust during Eocene to Oligocene following the Pyrenean Orogeny. It consists of various rock types including nepheline syenite, syenite, nepheline diorite toge...
