Petrogenesis of the Wadi Dib alkaline ring complex, Eastern Desert of Egypt
The Wadi Dib magmatic complex is the oldest known alkaline ring complex in the Egyptian part of the Pan-African orogenic belt. Rb-Sr isotope data for seven samples suggest a Vendian age of 578=k16 Ma, and a 87Sr/S6Sr initial ratio of 0.7048±0.0010. The igneous complex has a diameter of 2 km and was emplaced within granodioritic Pan-African host rocks at the intersection of two faults. It shows ...
متن کاملMineral chemistry and petrogenesis of the Amphibolites of Geysour metamorphic complex, east of Gonabad
The Geysour area is located east of Gonabad and is a part of the northern Lut block. The rocks in this area include granitoid and metamorphic rocks. Based on field and mineralogical evidence, the protolith of amphibolite rocks are calc-silicate. The metamorphic rocks of this region are divided into metapelites and amphibolites. Textures, such as post-tectonic garnet and random amphiboles, are i...

متن کاملPetrogenesis of the Tarr albitite-carbonatite complex, Sinai Peninsula
Large albitite bodies associated with explosive brecciation, fenite aureoles, intrusive carbonate rocks, olivine dolerites, and copper mineralization are described from the Dead Sea rift region in the south-eastern Sinai Peninsula. The main carbonate phases comprise breunnerite and dolomite with actinolite the main phase in the fenites. Field and isotopic evidence indicates that the intrusive c...
متن کاملMorphology and Petrogenesis of Pillow Lavas from the Ganj Ophiolitic Complex, Southeastern Kerman, Iran
The Upper Cretaceous Ganj complex, a part of the Jazmurian ophiolitic belt, is located on the western boundary of Jazmurian depression and separated from Kahnuj ophiolitic complex by north-south trending Jiroft fault. The complex consists of lava flows, pillow lavas, acidic plutonic and sedimentary rocks which are intruded by northwest-southeast trending dykes. It does not resemble a classical ...
