This study was carried out on granitic rocks from the Biga Peninsula in order to investigate petrographic, and mineralogical properties comparison with mechanical strength properties. conducted four different locations where outcrop north south Peninsula: Lapseki (Şevketiye granite), Ezine (Kestanbol Bayramiç (Yassıbağ Edremit (Eybek granite). Field observations detailed petrographic studies of...
The vein-type Chomalu polymetallic epithermal deposit, located in the Tarom-Hashtjin Metallogenic Province (THMP), western Alborz, formed two separate mineralized zones controlled by fault within andesite and olivine basalt host rocks. deposit occurs adjacent to Varmarziar quartz monzonite, monzodiorite, monzosyenite intrusions. Ore mineralization consists of three stages; (i) an early stage do...
The stability of tunnel site depends upon the deformation behaviors surrounding rocks, including joint density, mineral composition, micro cracks, and grain boundaries. aim this study was to analyze mechanical properties Besham Complex in Northern Pakistan terms petrography analysis. complex is prone as it bounded by Main Mantle Thrust (MMT) north, Thakot fault (Tf) east, Swat block west. In ar...
roudgaz prospect area is a cu, sn, pb, zn, and au polymetal vein system located to the southeast of gonabad and in the northeast of lut block. oxidan subvolcanic tertiary rocks with monzonite to monzodiorite porphyry composition intruded the metamorphic rocks of middle jurassic. the majority of intrusive bodies are affected by carbonation, argillic, sericitic, and silicification-tourmaline alte...
The Lower Yangtze River Belt (LYRB) is a well-known and important base area with regard to Cu polymetallic resources in China. Large deposits the LYRB are strongly associated Cretaceous adakitic rocks. However, petrogenesis of Early adakites temporal–genetic relationship mineralization still disputable. Dongguashan (DGS) deposit Tongling ore cluster one largest LYRB. DGS intrusion mainly compri...
In the Western Sangilen (Tuva–Mongolia microcontinent, Central Asian Orogenic Belt, Russia) rare mineral ferrohögbomite-2S2N, for first time, was found in a deep-seated contact aureole of early Paleozoic Bayan-Kol gabbro-monzodiorite intrusion. The rocks are diatexites roof pendant, where metamorphics gabbronorite. Diatexites formed as result strong melting and desilication quartz-bearing kyani...
The genesis of Eocene to Early Oligocene plutons and dykes emplaced in the suture zone between two colliding continental blocks southeastern Iran has been subject debate concerning processes that formed magmas influenced their intrusive history. We report geological, geochemical, mineralogical isotope evidence constrains origin Lakhshak plutonic complex. SiO2 contents granodioritic pluton dacit...
The late Pan-African Fawakhir, Urn Had and Urn Effein Granite Plutons in the Egyptian Central Eastern Desert are small, elongate to circular bodies of pink monzogranite and syenogranite, and grey monzodiorite. Structural investigation of the intrusive contacts of these plutons reveals marginal sub-horizontal intrusive sheets as magma injection along preexisting flat-lying structures including m...
three intrusive granitoid bodies from northwest saveh, central iran, are embedded in volcanic sedimentary rocks of the eocene,forming isolated small outcrops: khalkhab quartz monzodioritic units (sio2: ~52-57 wt %) to the northwest, neshveh granodioriticunits (sio2: ~62-71 wt %) to the northeast, and selijerd granodioritic units (sio2: ~63-69 wt %) to the southeast. the khalkhab unit iscomposed...
