The Natanz plutonic complex is located in north of Isfahan and in the Orumieh – Dokhtar magmatic belt. Based on petrographic studies, the Natanz complex is composed of six rock types, which are granodiorite, quartz-diorite, diorite, gabbro, quartz-monzonite and granite monzogranit. The intrusive rocks of Natanz are related to the calc-alkaline magmatic series and I-type granitoids. These rocks ...
The Kashmar granitoid (43.5–42.4 Ma) forms an extensive part of iron–oxide type magmatic belt in northern side of the Doruneh Fault. It includes plutons of tonalite, granodiorite, granite and alkali feldspar granite which are metaluminous (ASI ≤ 1) in nature. They contain dominantly felsic minerals, representing I–type granites with low–temperature and low–pressure characteristics. According to...
The development of glass-ceramic foam has received significant attention in building and construction, given its potential for sustainability. This study investigated the low-temperature route fabricating foams from mining waste. feasibility one-step or chemical-aided sintering using granite powder, a naturally sourced waste, rather than already heat-treated wastes such as glass fly ash been ex...
Jebale-Barez plutonic complex is composed of granitoid intrusive bodies and is located in the east- northeast Jiroft, southeastern Kerman Province. The plutonic complex is composed of granodiorite, quartzdiorite and granite - alkaligranite. The Plutonic rocks are mainly composed of plagioclase, alkali-feldspar, biotite, amphibole and quartz. Based on microprobe analysis, plagioclase composition...
The studied bodies are located in the west of Urumieyeh Lake and northeast of Oshnavieyeh, in the Sanandaj-Sirjan structural zone. Compositionaly, these bodies are formed from gabbro-diorite (Dourbeh) and granite (Nari). Gabbrodiorite rocks are composed of plagioclase (andesine to bytownite), amphibole (calcic group and magnesio-hornblende-tschermakite-hornblende type) and pyroxene (augite) as ...
Low-reactive completely decomposed granite (CDG) was successfully synthesized by thermal activation with the addition of NaOH at low alkali/CDG mass ratio 0.1/1. During alkali fusion, degree amorphicity CDG rich in kaolinite (Al2Si2O5(OH)4) increased and a significant reduction peak intensities occurring between 20 45 (o2 theta) observed. Reactivity analysis indicated that, initial requires hig...
The basement rocks encountered in exploratory boreholes drilled for exploration and evaluation of coal deposits in Thar Parkar district, Sindh Pakistan have formed the basis for present studies. The basement complex was penetrated through eighteen boreholes at drill depth range from 112 to 279 meters. These rocks were identified in field as Pink and Grey Granites.. The basement rocks are of Ign...
Summary One-part geopolymers, known as “just add water” (JAW), alkali-activated formulation is presented in this work. This work reveals the design and development of short-term properties JAW geopolymers for use oilwell cementing well abandonment. Granite-based mix designs normalized with a byproduct slag small amount microsilica precursors were developed. The solid activator composed potassiu...
Geochemical Aspects of Na-Metasomatism in Sargaz Granitic Intrusion (South of Kerman Province, Iran)
The Sargaz granitic intrusion has been emplaced in Sargaz ophiolitic suite, south-east of Sanandaj-Sirjan metamorphic zone, south of Kerman province. The central part of the intrusive body contains pinkish coarse-grained granite, but the fractured northern part, neighboring Chah-Mazraeh fault, has been subjected to pervasive Na-metasomatism and related subsolidus reactions. In the northern alte...
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...
