Jadeitite - Wikipedia
Jadeitite consists almost entirely of the pyroxene mineral jadeite and is typically mined as a source of the ornamental rock or gemstone, jade. Occurrences include Myanmar, Guatemala, Japan, Kazakhstan and in the Coast Ranges of western North America.
Jadeitites and Plate Tectonics | Annual Reviews
Jadeitite is a relatively rare, very tough rock composed predominantly of jadeite and typically found associated with tectonic blocks of high-pressure/low-temperature metabasaltic rocks (e.g., eclogite, blueschist) in exhumed serpentinite-matrix mélanges.
The Burmese Jade Mines belt: origins of jadeitites, serpentinites, …
2023年7月21日 · Jadeitites are uncommon rocks made up almost entirely of jadeite pyroxene (NaAlSi 2 O 6).
Jadeitites north of the fault have been found associated with other high-pressure / low-temperature metamorphic rocks (eclogites, blueschists, and garnet amphibolites) in serpentinites from Saltán, Baja Verapaz to Río Hondo, Zacapa and near Rosario, Izabal.

2013年6月1日 · Jadeitite is a rock composed primarily of jadeitic pyroxene that is found in a small number of occurrences associated with high-pressure–low-temperature (HP–LT) rocks, such as blueschist, garnet-amphibolite and eclogite, within serpentinite-matrix mélange.
Jadeite - Wikipedia
Jadeite is a pyroxene mineral with composition Na Al Si 2 O 6. It is hard (Mohs hardness of about 6.5 to 7.0), very tough, and dense, with a specific gravity of about 3.4. It is found in a wide range of colors, but is most often found in shades of green or white.
A new jadeitite jade locality (Sierra del Convento, Cuba): first …
2008年12月12日 · In this paper, we document for the first time the occurrence of jadeite jade in eastern Cuba. The new locality is in the subduction mélange of Sierra del Convento (Fig. 1), which correlates with the Rio San Juan mélange (García-Casco et al. 2008; Lázaro et al. 2008).
