Undoubtedly, involving more tools, datasets, and techniques for detecting the mineralized areas sharply narrow zones to be investigated delivered, in most cases highly potential zones. Consequently, this study is an attempt apply remote sensing data including Sentinel 2 ASTER, field observations, petrography of hydrothermal alteration processes, ore microscopic investigations, X-ray examination...
We conducted rock magnetic, mineralogical, sedimentological and geochemical analyses on a sediment core (MD161/Stn-11) retrieved from complex marine sedimentary system of Krishna-Godavari (K-G) basin to delineate the control mass transport deposits (MTD's) methane-induced diagenesis magnetic record. Four zones (Z-I, Z-II, Z-III, Z-IV) were defined based signatures. The signal is mainly carried ...
Eocene intermediate to felsic subvolcanic rocks of the Torud-Ahmad Abad magmatic belt (TAMB), in northern part Central Iran zone, are exposed between Torud and Ahmad regions South-Southeast Shahrood. These igneous include hypabyssal dacite, trachyte, andesite, trachy-andesite, basaltic andesite; they mainly composed phenocrysts microcrystalline groundmass pyroxene, amphibole, plagioclase, with ...
Stream sediment sampling is a significant tool in geochemical exploration. The stream composition reflects the bedrock geology, overburden cover, and metalliferous mineralization. This research article focuses on assessing selected trace element concentrations sediments interpreting their inter-element relationships using multivariate statistical methods. Tagadur Ranganathaswamy Gudda its surro...
Abstract The principal objective of the Hominin Sites and Paleolakes Drilling project (HSPDP) is to study relationship between climate environmental change implications on human evolution in eastern Africa. For this purpose, HSPDP has recovered a 228 m core Chemeron Formation Baringo Basin (Kenya). spans approximately 3.7 Myr, from around 1.6 5.3 Ma, yielded many vertebrate fossils, including f...
The Alvand complex (Hamedan province) comprises several bodies ranging from acidic to intermediate and basic compositions intruded in the regional metamorphic sequence of the area (the Hamedan phyllites) during various magmatic episodes in Jurassic. In northern part of the complex (the Cheshmeh-ghasaban area) there are some outcrops of hornblende gabbro and olivine gabbronorite. The olivine-gab...
the chah morra cu occurrence is located 15 to 20 km north of toroud village, south of shahrood. in this area, cu deposits are hosted by the andesitic sequence and most of rocks in this area are composed of andesite. veins contain minerals such as digenite, bornite, covellite, malachite, cuprite, tenorite, native copper and fe oxide and hydroxides. also some orthomagmatic magnetite and chalcopyr...
