کانسار آهن خسروآباد در شمال شرقی سنقر و 1 کیلومتری روستای خسروآباد قرار گرفته است. آنومالی های آهن این منطقه در چند نقطه در داخل سری های ولکانیکی و آهکی به نام سری سنقر قرار دارد، که تحت تاثیر دگرگونی ناحیه ای تا حد شیست سبز دگرگون شده اند. نتایج بررسی های انجام شده، نشان می دهد که کانه اصلی کانسار هماتیت و کمتر مگنتیت است که به صورت توده ای، پرکننده ی فضای خالی، جانشینی رگه ای و دانه ای کانی س...

kuh-e-faryadoon and kouli kosh iron deposits are hosted by regional metamorphic rocks of sanandaj-sirjan zone around deh-bid area. plugs and domes of acid rocks protrude these metamorphic rocks. a mylonitization event is super imposed on acid rock and metamorphic complexes. field, petrological and geochemical studies have shown that (1) iron mineralization have occurred during mylonitization in...

The Jagpura Au-Cu deposit is situated within the Aravalli craton in northwestern part of India. In present work, petrography, mineral chemistry, fluid inclusion and sulfur isotopic compositions were used to study deposit. ore association arsenopyrite, loellingite, chalcopyrite, pyrrhotite pyrite, along with native gold, magnetite apatite. gold fineness ranges from 914–937‰ (avg. 927‰). presence...

During the latter part of the Phanerozoic, numerous iron oxide(-Cu-Au) (IOCG) systems formed in parts of the Cordillera of North and South America. They occur in diverse tectonic and magmatic settings with considerable variety in deposit associations and characteristics. Although there are general patterns, there is no simple, all-encompassing descriptive model; a comparison with the diversity ...

Brownfield areas are important targets of exploration; however, the extensive drilling present in these has not fully exploited their prospective potential. The appropriate use drill hole cores can play an role deep exploration. We a case study iron oxide-copper-gold (IOCG) Furnas Southeast deposit, located Carajás Mineral Province, Brazil. This deposit disseminated chalcopyrite, bornite and go...

Albitite-type uranium deposits are widely distributed, usually of low grade (<1% U3O8), but are often large and collectively contain over 1 million tonnes of U3O8. Uranium is hosted in a wide range of metamorphic lithologies, whose only common characteristic is that they have been extensively mylonitised. Ore minerals are disseminated and rarely in megascopic veins, within and adjacent to albit...

The Salobo iron oxide copper-gold (IOCG) deposit host an important Cu-mineralization of the Carajás Mineral Province. ore is characterized by association (bornite-chalcocite-digenite) hosted magnetite and biotite-garnet schists. These rocks record distinct stages superimposed hydrothermal alteration dynamic metamorphism. Three different occurrences constitute bodies: a pristine to inclusion-poo...
