Chromespinel and Magnetite as Indicators for Recognition of Genesis and History of Serpentinites in Baft Ophiolite Mélange (Kerman Province in Iran) [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2013
Baft ophiolite mélange is a part of Naein-Baft ophiolite (southeast of Kerman province in Iran). Serpentinites from Baft ophiolite mélange contain different types of spinels such as chromite, chromespinel, ferritchromite and magnetite which can reveal ...

Chromitites of the Akkarginskiy massif (the Southern Urals)

open access: yesВестник Пермского университета. Геология, 2018
We consider the geological features of ultramafic rock and chrome ore deposits. It is shown that all studied deposits are podiform in morphology that is typical for the ophiolite ultramafic rocks. Morphological and chemical features of the accessory and oreforming spinels are described.

Hantaishir ophiolite complex and chromitite, Altai region, Mongolia

open access: yesThe Journal of the Geological Society of Japan, 1998
モンゴル国アルタイ地域には超マフィツク岩川のメンバーにクロミタイトを伴うオフィオライトがあり, ハンタイシャーオフィオライトと呼ばれている. ユーラシア大陸のほば中心に位置する本オフィオライトが記録している上部マントルから地殻にかけての情報は広大な大陸形成前のテクトニクスを考えるうえで重要である. 特に超マフィック岩に記録された岩石・鉱物・鉱床学的情報は,マントルプロセスを明らかにするうえで興味深い. ここではJICAプロジェクト(JICA-IGMR project)の一環として行われた調査の一端としてハンタイシャーオフィオライトと伴われるクロミタイトの露頭を紹介する.
