This study investigates the concentration, potential of toxicity, and source rocks of seven toxic elements (As, Cd, Cu, Cr, Pb, Zn, and Ni) in the sediments of four salt domes on the north of Hormuz Strait (Hormuz, Pol, Gachin and Angouran). In this regard, to determine the origin of toxic elements in the sediments of […]
Khunik gold prospecting area is located in the eastern part of Lut block, eastern Iran. Main rock units are andesite, agglomerate, latite, dacitic lava, rhyodacite, volcanic breccia and conglomerate. Geological and geochemical evidences indicate low to medium sulfide gold mineralization. Mining activates accumulate heavy metals in soil and water that are associated with harmful effects […]
Mikkes River Basin is located in the north-center of the Kingdom of Morocco (North-West of Africa). It comprises of three different zones which represent diversified geologies and which shelter a phreatic and confined aquifer in Saïs plain and a shallow aquifer in El Hajeb Ifrane Tabular. This research aims to highlight the potential impact of […]
This study is to investigate the physico-chemical parameters and trace metal’s concentrations (Cd, Pb, Cu, and Zn) in water and surficial sediments (0-5 cm) samples in the Kebir-Rhumel Wadi, north-eastern Algeria. Trace metal concentrations was determined using flame atomic absorption spectroscopy. The mean values of the physico-chemical parameters of the Wadi water samples are consistently […]
The skarn type mineralization has long been accepted as an interaction of magma and the host carbonate rocks. Most researchers have considered the iron deposits in the northern Sanandaj Sirjan zone (Kurdistan area) as skarn-type mineralization which has been generated during the injection of the granitoid bodies into the host carbonate. The calculation of normative […]
In this research, the biostratigraphy, microfacies, and depositional environment of carbonate sediments of the Jahrum Formation will be investigated based on microscopic textures and the distribution of benthic foraminifera. The Jahrum Formation was measured from Kuh-e-Hamze Ali in the Chaharmahal Bakhtiari province (Zagros Basin, Iran). The biostratigraphic analysis of this formation has led to the […]
Among several distribution characteristics, temporal distribution characteristics of earthquakes provide the most crucial information on the temporal patterns of past seismicity. Identification of such patterns is required for seismic hazard, forecast studies and also simulation of future seismicity. The confusion of how to model the past temporal patterns does limit further development:. Though the Poisson […]
The concentrations of heavy metals (inorganics) and poly aromatic hydrocarbons (organics) were determined in soils around fueling stations and automobile workshops. Mean concentrations of nickel, lead, cadmium and vanadium were 636, 1379, 12.0 and 18.0 µg/kg, respectively. Flourene, benzo (a) pyrene, benzo (b) fluoranthene and benzo (ghi) pyrelene recorded means of 2.01, 2.014, 1.14 and […]
The Sahand volcano (Kuh-e-Sahand) is located in NW Iran, about 60 km E of Lake Urumieh and 40 Km SSE of Tabriz. The volcano is a stratovolcano and is dominated by pyroclastic materials and lava flows in the Miocene-Quaternary. The Mio-Pliocene volcanic rocks are exposed in the Southwest of Bostanabad (Arvanehkuh, Biukdagh, and Ghapandagh masses) […]
The magmatic evidence of the Neotethys opening in Iran, such as the Late Paleozoic A-type granitoids, was mainly discovered along the Sanandaj-Sirjan Zone and parallel to the Neotethys suture. Therefore, they may provide important clues about the geodynamic evolution of the Sanandaj-Sirjan Zone. The South of Lake Urmia (SLU) granite is situated near the Khalifan […]
