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 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 […]
The present study seeks to characterize Ni-Cu mineralization at Mpemba hill in Blantyre, southern Malawi by using aeromagnetic and drill hole data. The area has been under-explored for this im-portant economic commodity and as such not much is known regarding its mineralization poten-tial. The minimal curvature gridding technique was utilised to grid the aeromagnetic data, […]
Knowledge of the in situ stress state is an essential component in rock engineering, especially for underground spaces in civil, mining, petroleum geomechanics and geothermal energy projects. The most accurate methods of measuring the in situ stress of rock are direct and field measurement methods. However, since these methods are time-consuming and costly, indirect rock […]
The prospecting area is located in the eastern part of Iran. Aster and Landsat 8 satellite images were processed with different spectral analyses techniques to detect the clay representing the alteration zones, with emphasis on bentonite occurrences in the study area. Band ratio (BR), Spectral Angle Mapper (SAM), Mixture Tuned Matched Filtering (MTMF), Principal Component […]
The benthic and planktonic foraminiferal contents of the Bangestan Group (Sarvak, Surgah and Ilam formations) in the Sepid Kuh anticline in the Lorestan Zone, W Iran, were studied. Bangestan Group consists of limestone, argillaceous limestone, dolomitic limestone and marl with thickness of 5400 m. In this section Bangestan Group overlies Garu Formation disconformably and its […]
The Burdigalian carbonate of the Central Iran contains very well-preserved specimens of Kuphus polythalamius. The tube of Kuphus polythalamius is a calcareous secretion that enables Pelecypoda to live in the mud of shallow seas. This research focusses on the Paleontology and taphonomy of the Kuphus polythalamius of the Member F (Qom Formation) in the southeast […]
The section located in WadiHajar, Haditha area, west of Iraq was sampled for microfacies analysis of the Euphrates Formation. Microfacies analysis led to the recognition of eleven microfacies association types; Mudstone, Peloidalgrainstone, ooidsgrainstone, Miliolids-Peneroplidsgrainstone, Peneroplidsgrainstone, Echinoidalwackestone, Miliolidswackestone, Alveolinidswackestone, Bioclasticpackstone, Peneroplidspackstone and Rotaliidspackstone, were deposited in restricted marine, shoal, and open marine environments. The study of […]
Magnetite-apatite mineralization in Tarom Mountains at the western part of Alborz-Azerbaijan belt originated from quartz monzonite magma and belongs to high K calc-alkaline, showing a post-collision tectonic environment. The negative trend from LREEs to HREEs is consistent with the spider pattern of the subduction areas. In this article, the recovery of the rare-earth elements (REEs) […]
Investigating the fossil-bearing horizons of the Kond Formation in the Saran area resulted in the identification of Sardinellasardinites (Heckel 1850) belonging to the family of Clupeidae Bonaparte (1831) for the first time the east of Tehran province. Furthermore, biostratigraphic analyses based on the presence of benthic and planktonic foraminifera in this area demonstrate that the […]
