In many practical geochemical systems that are at the center of providing indispensable energy, resources and service to our society, (bio)geochemical reactions coupled with other physical processes, such as multiphase flow, fracturing deformation. Predictive understanding these processes in hosting evolving porous media is key design reliable sustainable practices. this article, we provide a b...
sarcheshmeh porphyry copper deposit is located 65 km southwest of rafsanjan in kerman province. the sarcheshmeh deposit belongs to the southeastern part of urumieh-dokhtar magmatic assemblage (i.e., dehaj-sarduyeh zone). intrusion of sarcheshmeh granodiorite stock in faulted and thrusted early-tertiary volcano-sedimentary deposits, led to mineralization in miocene. in this research, the mass ch...
The science needed to inform management of environmental flows temporarily closed estuaries and coastal lagoons is decades behind the state knowledge for rivers large embayments. These globally ubiquitous small systems, which are often seasonally ocean’s influence, under particular threat associated with hydrologic alteration because changes in atershed land use, water use practices, climate ch...
The Rahmatabad Kaolin deposit is located about 25 km southwest of Nain. This deposit is formed by alteration process from Eocene volcanic rocks and pyroclastic units. Mineralogical studies display that the kaolinite, jarosite, hematite, quartz, calcite, anortite, alunite, diaspore, chlorite, montmorillonite, illite, albite, orthoclase, halite, sanidine, goethite, malachite, azurite and sericite...
Abstract Stained glass windows are a precious heritage to pass on future generations. However, medieval stained particularly altered due their chemical composition and the effects of climatic (mainly water temperature), environmental (pollution) biological factors. In this review, we present alteration patterns observed ancient Si-K-Ca windows. To better understand formation mechanisms determin...
