New contributions to the understanding of Kiruna-type iron oxide-apatite deposits revealed by magnetite ore and gangue mineral geochemistry at the El Romeral deposit, Chile
(Elsevier, 2018)
Iron oxide-apatite (IOA) or Kiruna-type deposits are an important source of iron and other elements including REE, U, Ag, and Co. The genesis of these deposits remains controversial, with models that range from a purely ...
The geochemistry of apatite from the Los Colorados iron oxide–apatite deposit, Chile: implications for ore genesis
(Springer Verlag, 2019)
Apatite grains from the Los Colorados iron oxide–apatite (IOA) deposit, the largest IOA deposit in the Chilean Iron Belt (CIB), exhibit significant intracrystalline spatial variability with respect to the concentrations ...
Trace element geochemistry of apatite and magnetite in gold systems of the Alta Floresta mineral province: petrogenetic and metallogenic implications
(Universidade Estadual Paulista (Unesp), 2020-08-05)
Minerais indicadores, como apatita e magnetita, são úteis para discriminação entre rochas estéreis e halos de alteração hidrotermal, visto que eles apresentam composições químicas contrastantes que permitem-nos inferir a ...
Giant Kiruna-type deposits form by efficient flotation of magmatic magnetite suspensions
(Geological Soc Amer, 2015)
Kiruna-type iron oxide-apatite (IOA) deposits are an important source of Fe ore, and two radically different processes are being actively investigated for their origin. One hypothesis invokes direct crystallization of ...

As rochas intrusivas da Formação Serra Geral na Porção leste da Bacia do Paraná no Estado de São Paulo: Aspectos petrográficos e geoquímicos - Resultados preliminares
(2005-12-01)
The purpose of this paper is to present preliminary aspects of the petrography and chemistry of intrusive rocks (sills and dykes) from the eastern portion of the Parana Basin in the State of Säo Paulo. Data from 80 samples ...
