西南日本の熱変成超苦鉄質岩体中のかんらん石と輝石の組成変化に関する覚書 [PDF]
, 2010 This short article presents some diagrams showing the compositional variations of primary and metamorphic olivine, orthopyroxene and clinopyroxene in peridotites and serpentinites from thermally metamorphosed ultramafic complexes in SW Japan. In contrast

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 2, February 2023., 2023 Abstract The extent of partial melting of peridotites is a function of temperature, pressure, and fluid supply. Understanding the petrogenesis of ultra‐depleted peridotites is important for elucidating mantle potential temperature and the role of water in the mantle.

A neoproterozoic age for the chromitite and gabbro of the Tapo Ultramafic Massif, Eastern Cordillera, Central Peru, and its tectonic implications [PDF]
, 2011 The ultramafic-mafic rocks of the Tapo Complex are exposed in the Eastern Cordillera of the Central Peruvian Andes. This complex is composed of serpentinised peridotites and metabasites with some podiform chromitite lenses and chromite disseminations and

Genetic Link between Podiform Chromitites in the Mantle and Stratiform Chromitites in the Crust: A Hypothesis [PDF]
Minerals, 2021 No genetic link between the two main types of chromitite, stratiform and podiform chromitites, has ever been discussed. These two types of chromitite have very different geological contexts; the stratiform one is a member of layered intrusions, representing fossil magma chambers, in the crust, and the podiform one forms pod-like bodies, representing ...

Testing Trace-Element Distribution and the Zr-Based Thermometry of Accessory Rutile from Chromitite
Minerals, 2021 Trace element distribution and Zr-in-rutile temperature have been investigated in accessory rutile from stratiform (UG2, Merensky Reef, Jacurici), podiform (Loma Peguera), and metamorphic chromitites in cratonic shields (Cedrolina, Nuasahi).

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,

The structure and cryptic layering of the Pados-Tundra ultramafic complex, Serpentinite belt, Kola Peninsula, Russia [PDF]
Bulletin of the Geological Society of Finland, 2017 The Paleoproterozoic Pados-Tundra ultramafic complex, ~6 x 1.5-2.1 km in size and ~2.1 Ga in age, located in the Kola Peninsula of Russia, is the main representative of the Serpentinite belt in the northern Fennoscandian Shield.
