economic geology of the xiv iron-oxide prospect, bafq mining the origin of the massive iron oxide deposits related to igneous rocks has been the subject of a long-standing and hot debate for the last hundred years. among these deposits, the so-called kiruna-type ores have attracted the most attention. several genetic models have been proposed for this specific type of massive iron oxide deposits. global feo isotope correlation reveals magmatic origin of the origin of giant kiruna-type iron ores has been debated for nearly 100 years. this study employs extensive stable isotope data from kiruna-type ores worldwide and magmatic and hydrothermal the geology and mining operations of the kiirunavaara mine the kiruna district is the type locality for kiruna-type iron oxide-apatite deposits (vogt, 1927; geijer, 1931; smith et al., 2009). while sharing many similarities with iron oxide copper gold (iocg) deposits, kiruna-type ores are recognised as a distinct, but possibly related, type (williams et al., 2005). geology of the northern norrbotten ore province, northern swedenrange of deposits occur, the most important types being stratiform copper deposits, iron formations, kiruna ­ type apatite iron ores and epigenetic copper ­gold deposits. a common feature of most deposits is that they are hosted by palaeoproterozoic metavolcanic or metasedimentary rocks. a number of key hydrothermal fluid evolution and metal transport in the read "hydrothermal fluid evolution and metal transport in the kiruna district, sweden: contrasting metal behaviour in aqueous and aqueouscarbonic brines, geochimica et cosmochimica acta" on deepdyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. belt type iron separator installation for molybdenum in iraniron and fe mn mineralisation in iran: implications researchgate. mar 24, 2015 publication details, including instructions for authors and . deposits) and cenozoic (kiruna type, iron oxideopperold . iron m ineralisation/occur rences in. iran. zone/metallo genic belt .. the middle to late permian by separating the cimmerian .. mineral chemistry of magnetite from magnetite frietsch r (1978) on the magmatic origin of iron ores of the kiruna type. econ geol 73:478485 crossref google scholar frietsch r, jan-anders p (1995) rare earth elements in apatite and magnetite in kiruna-type iron ores and some other iron ore types. metallogeny of the northern norrbotten ore province, northern the northern norrbotten ore province in northernmost sweden includes the type localities for kiruna-type apatite iron deposits and has been the focus for intense exploration and research related to fe oxide-cu-au mineralisation during the last decades. on the chemical composition of the ore breccia at luossavaara an important argument for a magmatic affiliation of the kiruna type of ore is the presence of ore breccia which accompany the main ore bodies. according to parák (1975a and b) the main ore bodies are iron oxide cu-au monograph paper reference listÖdman, o.h. 1950 - manganese mineralisation in the ultevis district, jokkmokk, northern sweden. part 2: mineralogical notes. sveriges geologiska undersökning arsbok 44, no.2, ser c. no.516. parak, t. 1975 - kiruna iron ores are not "intrusive magmatic ores of the kiruna type" economic geology 70, 1242-1258.

copper-gold (iocg) type mineralisation in themineralisation and the associated alteration exhibits many characteristics of iron oxide-copper-gold (iocg) type deposits. the contained mineralisation is dominated by iron oxide and fluorite and is accompanied by a diverse polymetallic association, with anomalous fluorite, copper, gold, barite, uranium and lree. major styles of mineralization and hydrothermal alteration and zoning of hydrothermally altered rock, the age and type of mineralization and hydrothermal alteration, and trends or patterns of veins and faults. these areas were differentiated in order to characterize and contrast the geochemical signatures of solids and waters in a variety of mineralized areas. in this kiruna iron project for personal use only.auflagship kiruna iron project is 30km from the 2bt kiruna iron mine (owned by lkab) the worlds largest and most modern underground iron mine. global investment banks canaccordgenuity and pareto securities have been mandated to assist with the future funding of the kiruna iron project. nelsonite and kiruna-type depositsnelsonites and kiruna-type deposits. the former is named for an unusual deposit in nelson county, ia, and the lat-ter for the kiruna district in northern sweden. differences between nelsonites and kiruna-type deposits include the ti content of the iron oxides (thus the type of oxide in some the magnetite-apatite ore of the kiruna district, northern swedenthe kiruna orebody is also termed kiirunnavaara and is a part of the kiruna district which includes the deposits kiirunavaara, luossavaara, rektorn, per geijer orebody, henry orebody, nukutusvaara, tuolluvaara and haukivaara (fig.2). furthermore kiirunavaara is one of the proterozoic iron oxide (cu-u-au- ree) deposits (after hitzman et al, iron and femn mineralisation in iran: implications for more than 200 iron deposits with about 4 billion tons of iron ore have been discovered in iran. major iron oxide districts comprise the bafq-posht-e-badam back arc district in central iranian microcontinent, the ac kahoor and hormoz districts in the zagros mountain range, the gol-e-gohar and hamekasi deposits in the sanandajsirjan magmaticmetamorphic zone and also the sangan deposit east kiruna iron ore minewith an ore body 4km long, 80m thick and reaching a depth of 2km, lkabs kiruna is the worlds largest, most modern underground iron ore mine. since mining began at the site over 100 years ago, luossavaara-kiirunavaara ab (lkab) has produced over 950mt of ore, yet only one third of the original ore body has been extracted. kiruna iron project for personal use only.auflagship kiruna iron project is 30km from the 2bt kiruna iron mine (owned by lkab) the worlds largest and most modern underground iron mine. global investment banks canaccordgenuity and pareto securities have been mandated to assist with the future funding of the kiruna iron project. iron and femn mineralisation in iran: implications for more than 200 iron deposits with about 4 billion tons of iron ore have been discovered in iran. major iron oxide districts comprise the bafq-posht-e-badam back arc district in central iranian microcontinent, the ac kahoor and hormoz districts in the zagros mountain range, the gol-e-gohar and hydrothermal fluid evolution and metal transport in the in the area (bergstrom et al., 2001), although the ores underwent a second period of metamorphism and possibly hydrothermal alteration at ~1800ma (romer et al., 1994; smith et al., 2009). quartz veins cross-cut magnetite and/or hematite in these deposits (fig. 2a, b) and so cannot be directly linked to ore deposition. however, the quartz
