The study area is located in Khorasan Razavi Province, NW Gonabad and based on tectonic setting, it is situated in the north of Lut Block zone. Subvolcanic bodies intruded the andesitic lava flows and the pyroclastics rocks. These intrusive bodies consist of small stocks and dykes with composition from quartz diorite, monzodiorite to granite. Widespread alteration identified in southern region ...
The Haisyn complex rocks (sobites (Shcherbakov, 2005)), consisting of diorite-like and amphibolites, which biotite granites develop, is outcroping near the village Shumyliv along South Bug river in an abandoned open pit mine (on Shumyliv). are characterized by high magnetization according to magnetic survey results. A linear anomaly extends north-east direction (NE 69º) with a distance more tha...
Halakabad is located about 30 km south of Sabzevar. Basalt, andesite, hornblende andesite and hornblende dacite are the oldest volcanic rocks cropping out in the study area. Monzodiorite, quartz diorite, quartz monzodiorite, quartz monzonite, and hornblende quartz monzodiorite intruded the volcanic rocks. Application of component analysis is one of the methods that can help to reveal simpler pa...
sar-kuh porphyry copper deposit is located 6 km southwest of the sar-cheshmeh copper mine, kerman province, iran. based on field geology, petrography and fluid inclusions studies, four alteration types have been identified in the sar-kuh area. early hydrothermal alteration formed a potassic zone in the central parts of mamzar granite/grano-diorite stock and propylitic alteration in its peripher...
The 2020 Elliot Creek landslide-tsunami-flood cascade originated from an 18.3 Mm 3 rock slope failure in quartz diorite bedrock a valley undergoing rapid glacial retreat. We used airborne LiDAR and optical imagery to characterize the its surroundings. Using LiDAR, we determined that two rockslides (2020 older undated one) occurred on this shared common basal rupture surface. mapped main sets of...
