The Kazakhstan jadeitite deposit formed in the Early Paleozoic Junggar Balkhash fold system at ~450 Ma and is one of the world’s oldest jadeitite occurrences. The studied deposit occurs as inclusions in Chuerkulam’s shattered and schistositized serpentine mélange near Balkash Lake.
Three different jadeitite rock types can be seen in this area: (1) white jadeitite rock can be seen in the middle of the rock block; (2) coloured jadeitite with albite; and (3) altered (dark green) jadeitite rock: the edge of the jadeitite rock was altered and may contain mica, garnet, and other minerals.
Jadeitites occur predominantly in the central parts of Itmurundy zone, associated with metasomatic chlorite–zeolite, omphacite–jadeite and diopside–grossular–zeolite, which can be up to hundreds of meters. A distinct dark belt composed of chlorite and actinolite separates jadeitite blocks from the surrounding serpentinite. Although there is no evidence of the occurrence of high-degree metamorphism, these blocks exhibit varying degrees of albitization. In the mining area investigated in this study, jadeitite occurs as large tectonic blocks within serpentinite belts, with individual blocks having a size of up to approximately 13 m.

Omphacitite in dark green occurs as veins. Vivid green jadeitite can be seen in patches and veins between the omphacitite and porcelain-white jadeitite. The jadeitite from Kazakhstan also exhibits a weathered yellow hue, similar to that from Myanmar. P-type jadeite. |
