Abstract/NotesIn China, podiform chromite deposits are the primary source of domestic chromite supply. The main chromite deposits are distributed within the Jurassic-early Cretaceous ophiolites of the Yarlung-Zangbo Suture Zone (YZSZ) in Tibet, as well as the Paleozoic ophiolites in Inner Mongolia and Xinjiang. To clarify the metallogenic processes and the associated tectonic settings during the formation of chromite ores in China, this study delves into the petrological, mineralogical, and geochemical characteristics of representative chromitite samples collected from ophiolites in Tibet (Luobusa, Purang, Dongbo, Baer, Cuobuzha, and Dajiweng), Xinjiang (Sartohay), and Inner Mongolia (Hegenshan). Based on the compositions of chromite, these chromitites can be categorized into high-Cr and high-Al types. The mineral inclusions in chromites are mainly composed of silicates, base metal sulfides, and diverse platinum-group minerals (PGMs). PGM inclusions are more frequently detected in high-Cr chromitites compared to high-Al types. Chromitites from the YZSZ ophiolites are predominantly high-Cr types (Cr# 66–82), suggesting their origin from a boninitic melt in a suprasubduction zone (SSZ) environment. The Hegenshan and Sartohay chromitites are typically high-Al types (Cr# 50.5–52.8) and were formed from mid-ocean ridge basalt (MORB)-like magma. By integrating the information of country rocks, we conclude that the major chromite deposits in China are closely associated with distinct magmatism stages in a supra-subduction zone (SSZ) environment, especially during subduction initiation stages. For future chromitite prospecting, we propose that the ophiolitic massifs along the Yarlung-Zangbo suture zone in southern Tibet hold great potential.
