In this study, the salt weathering effects on engineering properties and weight loss potential of three types of granitoid rocks were investigated. Sodium and magnesium sulfates tests were performed on core and aggregate samples. The cyclic salt weathering tests on core samples were done up to 90 cycles, while these tests on aggregate samples were done up to 40 cycles. The results showed that d...
East misho granitoid intrusion body, a part of Alborz-Azarbaijan zone, is located about 60 Km north west of Tabriz, NW Iran. This pluton with an area of about 50 km2 has cut percamberian unmetamorpic sedimentary rocks and, is covered with Permian sedimentary rocks with igneous nonconformity. Litological composition of the studied pluton displays a range of alkali granite, monzogranite and syeno...
the dehno granite massive is located in the east dehno village and southern khomein city and within themetamorphic sanandaj–sirjan zone. the composition of these rocks include: granodiorite, quartzdiorite(tonalite), monzogranite and leucogranite. quartz, alkali feldspar, plagioclase, biotite, andalusite, hornblendemuscovite, tourmaline, zircon and apatite are examples of the existing major and ...
Older and younger granitoids are widespread throughout the basement rocks of NE Egypt. Therefore, they are played a significant role in the evolution of the Pan-African crust. The Wadi El Sheikh-Gabal Saint Katherine area comprise three distinctive magmatic granitoid suites, namely: (1) calc-alkaline older quartz monzodiorite-tonalite suite (COG), (2) calcalkaline younger monzogranite suite (CY...
The studied area located in south and south western Arak town and are the part of Sanadaj-Sirjan Zone. The plutonic rocks in Astaneh and Boroujerd areas are quartz diorite, granodiorite and monzogranite. In addition to plutonic rocks, subvolcanic rocks of rhyodacite composition are present in Astaneh area. In general, in these areass mineral assemblage is the same in different units. The common...
Late Neoproterozoic- Early Cambrian schists exposed in southwest of Zanjan in northwest Iran. Intrusion of Tertiary Korramdaragh monzogranite body within these schists have caused crystallization of porphyroblasts of hexagonal cordierite with cyclic radial sixling twin structure. Hexagonal cordierite consists of six optically sectors. Under microscope with crossed polarized, all of the sect...
Relevant data on the structure and composition of crystalline basement in Central México can be found by means plutonic, metamorphic, sedimentary xenoliths transported Neogene Quaternary volcanic eruptions within Trans-Mexican Volcanic Belt (TMVB). We present detailed major oxide trace elements concentrations, isotopic analysis thermobarometric estimations for a granitic xenolith an Early Mioce...
The Chang’anpu Molybdenum deposit occurs in the monzogranite intrusions Lesser Khingan Mountains-Zhangguangcai Mountains metallogenic belt. Previous work focused on study of deposits, including geological characteristics, mineralization time, S-Pb isotope, etc. However, systematic petrogeochemical intrusion and comparative analysis with other porphyry deposits region are lacking. Three dating s...
Hardly any previous studies have focused on the granitic dykes which intrude into Paleoproterozoic Liaohe Group in Liaodong Peninsula, northeast of North China Craton. In situ zircon U-Pb dating, Lu-Hf isotopic and geochemical analyses three representative monzogranite were taken this study. These relatively high content SiO2 (72.20%–74.78%) K2O (2.83%–6.37%), characteristics high-K calc-alkali...
