Improving Lithological Mapping by SVM Classification of Spectral and Morphological Features: The Discovery of a New Chromite Body in the Mawat Ophiolite Complex (Kurdistan, NE Iraq)

Remote Sensing, 2014
The mineral ore potential of many mountainous regions of the world, like the Kurdistan region of Iraq, remains unexplored. For logistical and sometimes political reasons, these areas are difficult to map using traditional methods.

Chromite in the Mantle Section of the Oman Ophiolite: Implications for the Tectonic Evolution of the Oman Ophiolite [PDF]

, 2015
Chromite in the Oman ophiolite is located in the mantle section of the ophiolite sequence and forms abundant small podiformdeposits throughout the length of the ophiolite (Rollinson, 2005).The Oman ophiolite has an exposed mantle section of ca 10 000 km2,

Geochemical behavior of chromium in minerals of high-Mg rocks, associated with granitoid massifs of the Urals

Литосфера, 2019
Research subject. High-magnesium rocks associated with the granitoid massifs of the Urals are represented by gabbro-diorites and their melanocratic varieties (hornblendites), as well as by diorites and quartz diorites.

Petrogenetic Implications for Ophiolite Ultramafic Bodies from Lokris and Beotia (Central Greece) Based on Chemistry of Their Cr-spinels

Geosciences, 2017
Cr-spinels from ultramafic rocks from Lokris (Megaplatanos and Tragana), and Beotia (Ypato and Alyki) ophiolitic occurrences were studied. These rocks comprise principally harzburgite with minor dunite. Small amounts of clinopyroxene-rich harzburgite and

Synthesis and Characterization of CaxNi1-xCr₂O₄ Compound and Studying the effect of the Dopant on its Structural and Optical Properties

مجلة بغداد للعلوم
Ca0.07Ni0.93Cr2O4 was synthesized using solid-state method at 1000°C for 6h. Structural properties were studied by using X-ray diffraction and compared with Nickel Chromite compound (NiCr2O4) which was prepared at the same temperature.

Determination of Chromite by X-ray Fluorescence Spectrometry with Sample Preparation of a Lower-Dilution Fusion

Yankuang ceshi, 2013
Chromite analysis is dominated by chemical analysis, which is a wel-established but complicated procedure. Chromite can also be analysed by X-ray Fluorescence Spectrometry (XRF), however, a high-dilution fusion is not conducive to low content elements ...
