Ilmenite (high Mg,Mn,Nb) in the carbonatites from the Jacupiranga Complex, Brazil

, 1983
Ilmenite occurs rarely in the carbonatite plug (five separate intrusions) of the Jacupiranga Complex, in the jacupirangite near the contacts, and in the banded reaction zones between carbonatite and jacupirangite.

Trace element distribution in primary sulfides and Fe–Ti oxides from the sulfide-rich pods of the Lac des Iles Pd deposits, Western Ontario, Canada : Constraints on processes controlling the composition of the ore and the use of pentlandite compositions in exploration

, 2016
There is an on-going debate as to whether the Lac des Iles Pd deposits (Ontario, Canada) are of magmatic or hydrothermal origin. An aspect of the deposits that has not yet been documented is the presence of sulfide-rich pods which occur throughout the ...

Hypersthene-ilmenite(/magnetite) symplectites in coronitic olivine-gabbronorites

, 1982
Symplectitic intergrowths of hypersthene (host) with ilmenite and minor magnetite (vermicules) in a gabbroic sill from the Precambrian of southwest Sweden occur as replacement products of olivine, and are thought to have formed simulataneously with the ...

Magnetite-hosted Cu-PGE and Fe-sulfide mineralization in 1078 Ma layered mafic intrusions in the west musgraves region of Western Australia

, 2017
Three mafic-hosted, magnetite-related prospects called Jameson, Navigator and Latitude Hill occur in the most evolved, upper parts of the 1078 Ma layered intrusions belonging to the Giles Complex, Musgrave Province, Western Australia. The hosting layered
