Titaniferous-Vanadiferous, Magnetite-Ilmenite Mineralization in a Mafic Suite within the Chhotanagpur Gneissic Complex, Bihar, India [PDF]
Titanium or vanadium metals or their alloys are important industrial metals/alloys. Because these resources are in short supply, the investigation of potential titaniferous-vanadiferous deposits needs special attention to bridge the supply-demand gap ...

Provenance of heavy minerals in the Quaternary deposits of the Lemme outcrop, Estonia, based on optical microscopy, X-ray diffractometry and scanning electron microscope microanalysis [PDF]
This paper is a methodological development, where optical microscopy, X-ray diffractometry (XRD) and microanalysis under a scanning electron microscope (SEM) were used for comparative determination of heavy minerals in Quaternary sandy sediments in the ...

Discrimination of Mineralization Types of Skarn Deposits by Magnetite Chemistry
There are different mineralization types for skarn deposits with various origins and ore-forming conditions. Magnetite is one of the main ore minerals in skarn deposits, but whether chemical compositions of magnetite can be used to discriminate different

Magnetite chemistry in the Dalli porphyry Cu-Au deposit, central Urumieh-Dokhtar Magmatic Arc (UDMA)
The Dalli porphyry Cu-Au deposit is located in the central parts of Urumieh –Dokhtar Magmatic Arc (UDMA). This deposit is formed via the emplacing of Miocene intrusions mainly containing diorite and quartz diorite within the Eocene andesite and ...

Zinc Contents of Mafic Micerals in Granitic Rocks, with Special Reference to Ore Chemistry [PDF]
In order to know the reason why the Cu/Zn-Pb ratios of skarn-type deposits related with the ilmenite-series granitic rocks are markedly higher than those related with the magnetite-series, comparative mineralogical studies were carried out for the two ...

Mineralogy and Petrology of an Olivine Diabase Sill Complex and Associated Unusually Potassic Granophyres, Sierra Ancha, Central Arizona [PDF]
The Precambrian Sierra Ancha sill complex, 700 to 800 feet thick, was intruded into flat-lying sedimentary rocks of the Apache Group in central Arizona. The bulk of the complex consists of a central layer of feldspathic olivine-rich diabase and upper and
