| Abstract: | The high-pressure metamorphic rocks in northeastern Jiangxi Province include such types of rocks as jadeite-bearing aegirine-augite albite amphibole schist, jadeite-bearing aegirine-augite quartz albitite, aegirine-augite-bearing amphibole quartz albitite, aegirine-augite-bearing albite amphibole schist, winchite quartz albitite, and magnesio-riebeckite quartz albitite. Mineral constituents consist mainly of jadeite, aegirine-augite, magnesio-riebeckite, winchite, magnesio-hornblende, actinolite, quartz, albite, rutile and sphene. The high-pressure metamorphic rocks underwent an isothermal decompressional retrograde process after the peak metamorphism. |
