Petrography, geochemistry and petrogenesis of Damavand volcano: Comparison of different volcanic generations
1-Introduction Damavand volcano was formed by explosive and non-explosive eruptions on the old eroded rock units (Mesozoic and older) of Central Alborz during the Quaternary period and formed two huge cone (Old and Young Damavand). Davidson et al. (2004) determined the time of Old-Damavand activity from 1800 to 800 thousand years ago by measuring Ar/Ar and U-Th/He methods. According to their ...
متن کاملBasaltic lava domes, lava lakes, and volcanic segmentation on the southern East Pacific Rise
Meter-scale DSL-120 sonar mapping and coregistered Argo II photographic observations reveal changes in eruptive style that closely follow the third-order structural segmentation of the ridge axis on the southern East Pacific Rise, 17°11’-18°37’S. Near segment ends we observe abundant basaltic lava domes which average 20 m in height and 200 m in basal diameter and have pillow lava as the dominan...
متن کاملPetrography, geochemistry and tectonic setting of the Gharabolagh intrusive mass in North Hashtrud, East Azarbaijan
The plutonic body of Bostanabad-Meyaneh belt formed during the Cenozoic magmatism on the weast Alborz-Azarbaijan zone. The Oligocene plutonic rocks consist of alkaligranite, granodiorite and biotitegranite, intruded into the Eocene volcanic-sedimentary rocks. The predominant textures are granular, graphic and perthite. Geochemical evidence reveals that they are cogenetic and have features typic...
متن کاملPetrography and geochemistry of carbonate hosted-rock in the Karavangah and Dehno Pb-Zn mines at the north of Kuhbanan, Kerman
The hosted-rocks of the Pb-Zn ore deposits in two mines of Karavangah and Dehno (north of Kuhbanan) contain carbonate rocks of the Shotori Formation (Middle Triassic).The identified carbonate facies consists of limestone and dolomite, but ore bodies mainly occurred in dolomite facies. Petrographic studies show that the dolomites can be divided into four classes including fine crystalline, mediu...
متن کاملDepartment of Mineralogy , Petrography and Geochemistry
Department of Mineralogy, Petrography and Geochemistry is the oldest Earth science department at the AGH University of Science and Technology. It was created in 1919 as one of the first six departments of the Academy of Mining and was initially named as the Department of Mineralogy and Petrography. The Department was organized by Professor Józef Morozewicz (1865–1941) who chaired the Organizing...
