Vestiges of early Earth's deep subduction and CHONSP cycle recorded in Archean ophiolitic podiform chromitites
Ophiolitic podiform chromitites from Phanerozoic orogens have been shown to preserve a
wealth of textures and inclusions that, in some way, trace earlier episodes of subduction and …

Interpreting high-temperature magnetic susceptibility data of natural systems
High-temperature susceptibility (HT-χ) data are routinely measured in Earth, planetary, and
environmental sciences to rapidly identify the magnetic mineralogy of natural systems. The …

Eight good reasons why the uppermost mantle could be magnetic
Abstract Wasilewski et al.(1979) concluded that no magnetic remanence existed in the
uppermost mantle and that even if present, such sources would be at temperatures too high …

Unusual massive magnetite veins and highly altered Cr-spinels as relics of a Cl-rich acidic hydrothermal event in Neoproterozoic serpentinites (Bou Azzer ophiolite …
If magnetite is a common serpentinization product, centimetric, massive and pure magnetite
veins are rarely observed in serpentinites. Unique example, in the Aït Ahmane ultramafic …

Magnetic Properties of Ferritchromite and Cr‐Magnetite and Monitoring of Cr‐Spinels Alteration in Ultramafic and Mafic Rocks
Spinel is a ubiquitous mineral in mafic/ultramafic rocks. Spinel cores chemistry is extensively
used as a petrogenetic proxy while their alteration phases, ferritchromite, and Cr‐magnetite …

Magnetic Cr‐rich spinel in serpentinized ultramafic complexes
In comparison to the six spinel end‐members in the spinel prism, magnetic information on
the intermediate spinel compositions is relatively poorly established. To investigate …
