Ge­ol­o­gy

Der Luobusa-Ophiolith liegt entlang der Luobusa Falten-Zone, die auch bekannt ist als Yarlung Zangbo (oder Brahmaputra) -Sutur-Zone. Er besteht hauptsächlich aus Mantel-Peridotiten und Duniten. Diese überlagern eine Misch-Zone aus Pillow-Lavas, Gabbros, Pyroxeniten und Feuerstein in einer Serpentinit-Matrix. Der Ophiolith hat eine Ausdehnung von 42 km in OW-Richtung und hat eine Erstreckungsfläche von ca. 70 km². Podiforme Chromit-Erze sind eingelagert in einer Dunit-Harzburgit-Lage, welche diskontinuierlich in einer Lage von Mantel-Peridotiten vorkommt.
