Texada Island (Figure 2-5-1) is with.in Wrangellia. Calcalkaline plutonism of the Coast plutonic complex is superimposed on this terrane. The northern part of the island is made up mainly ct basaltic amygdaloidal flows and pillovr lavas of the ?exad1 Formation (Karmutsen Fbrmation) overlain by massibe grqi limestone and white marble of the Marble Bay Fonnatio I (Quatsino Formation). These Upper...

Although it is widely accepted that shallow silicic magma reservoirs exist, and can feed eruptions, their dynamics longevity are a topic of debate. Here, we use field mapping, geochemistry, 3D pluton reconstruction thermal model to investigate the assembly eruptive history Reyðarártindur Pluton, southeast Iceland. Primarily, exposed constructed single rock unit, Main Granite (69.9–77.7 wt.% SiO...

Gazu copper deposit is located in the boundary of Tabas and Lut block, 65km southeast of Tabas and 15km southwest of Deyhouk. The dominant lithology in the area consists of Shotori dolomite and limestone and Shemshak shale and sandstone.  Intrusive rocks with intermediate composition are widespread and numerous in the area. They consist of diorite, monzonite, and quartz monzonite to granite. Mi...

Yeylagh-e-Gharechi porphyry copper deposit is located in the Arasbaran metallogenic belt at northwestern Iran, 25 kilometer of Ahar. Porphyry mineralization at the Yeylagh-e-Gharechi deposit occurred in post-Oligocene quartz monzonite and monzonite bodies which was hosted by Eocene volcanic rocks. Mineralization occurred as veins, veinlets and dissemination in hypogene zone. Supergene zone has ...

MA-II area is one of the most important parts of Cu-Au porphyry mineralization at Maherabad prospect area. Subvolcanic intermediate intrusive rocks (Upper Eocene), monzonite to diorite in compositions, intruded telescopically and are mostly altered. Monzonitic porphyries had major role in mineralization. These intrusive rocks are highly altered, have dense stockwork veinlets, and show highest g...

The Homond Cu-Au porphyry prospecting area is located southwest of Birjand. Subvolcanic monzonitic to dioritic rocks are highly altered. The main alteration zones are: quartz-sericite-calcite-pyrite, propylitic and carbonate. The content of major, trace and rare earth elements (REE) of the rocks changes due to alteration. The changes are less in some such as TiO2, MnO, P2O5, Nb, Gd, Y, Eu and h...

Measurements of thermal conductivity and thermal diffusivity have been made on two samples of Climax Stock quartz monzonite at pressures between 3 and 50 MPa and temperatures between 300 and 523 K. Following those measurements, the apparatus was calibrated with respect to the thermal conductivity measurement using a reference standard of fused silica. Corrected thermal conductivity of the rock ...

The study subvolcanic intrusion, comprising syenodiorite, monzonite and quartz-monzonite, is cropped out in Talkh-rud valley located in the northeast of Damavand volcano flank. This sub-volcanic intrusion possesses porphyritic texture and consists of plagioclase, alkali feldspars, phelogopite, amphibole, clinopyroxene, apatite and titanomagnetite. Evidences of disequilibrium such as zoning and ...
