Landsat-8 data for chromite prospecting in the Logar Massif, Afghanistan [PDF]

Heliyon, 2018
Chromite is widely distributed in the east and southeast of Afghanistan, especially in Logar Province. Chromite mineralization is podiform-type and is hosted in the stratigraphically lowest ultramafic rocks of the Logar Ophiolite Complex.

Origin of chromite nodules in podiform chromitite from the Kızıldağ ophiolite, southern Turkey

Ore Geology Reviews, 2021
Abstract Chromite nodule is unique in podiform chromitite of ophiolitic suites and there is no agreement on its petrogenesis. The nodular chromitites of the Kizildag ophiolite in southern Turkey contain typical chromite nodules, and here their geochemical compositions and crystallographic orientations have been analyzed to study the formation of ...

Genesis of the Sartohay Podiform Chromitite Based on Microinclusions in Chromite

Minerals (Basel, Switzerland)
Here, we present a petrographic and microanalytical study of microinclusions in chromite from podiform chromitites hosted by the Sartohay ophiolitic mélange in west Junggar, northwestern China, to investigate the parental magma evolution and chromitite genesis.

Interpretation of magnetic and geoelectrical data based on geological and mineralogical evidence in the podiform chromite prospecting, Khoy ophiolite, Northwest Iran

Journal of Economic Geology, 2021
Introduction Podiform chromite deposits are small magmatic chromite bodies formed in the lower section of an ophiolite complex. The Khoy ophiolite covers an extensive area in the northwest of Iran along the Iran-Turkey border.

Formation and Evolution of Chromitites in the Hongshishan Complex, Beishan Orogenic Collage, NW China: Constraints from Mineralogical Compositions, Re‐Os Isotopes and Platinum‐Group Element Geochemistry

Acta Geologica Sinica - English Edition, Volume 97, Issue 3, Page 727-743, June 2023., 2023
Abstract The Hongshishan chromitite deposits are situated to the north of the Beishan orogenic collage, in the southern part of the Central Asian Orogenic Belt. This study describes the mineral chemistry, Re‐Os isotopes and platinum‐group elements geochemistry of the Hongshishan chromitites for the purpose of constraining the origin, evolution and ...

Polyphase tectonic reworking of serpentinites and chlorite‐tremolite‐talc rocks (SW Spain) from the subduction forearc to intracontinental emplacement

Journal of Metamorphic Geology, Volume 41, Issue 4, Page 491-523, May 2023., 2023
Abstract The petrostructural and geochronological study of a poorly known ultramafic unit from SW Spain (Badajoz–Córdoba belt) combined with previous structural data permits disclosure of a history of metasomatism, tectono‐metamorphism, reworking and isotopic resetting related to a poly‐orogenic evolution in different geodynamic scenarios.

The importance of trace element analyses in detrital Cr‐spinel provenance studies: An example from the Upper Triassic of the Barents Shelf

Basin Research, Volume 33, Issue 2, Page 1017-1032, April 2021., 2021
Cr‐spinel from the Snadd and De Geerdalen formations are distinctly different from Cr‐spinel of the same depositional age to the east of the Uralian Orogen. Major element compositions of detrital Cr‐spinel in the Carnian Osipai Fm. north Siberia is consistent with Cr‐spinel from a large igneous province, while Snadd and De Geerdalen formation Cr‐spinel
