摘要
赣东北高压变质岩包括含硬玉霓辉石钠长角闪片岩、含硬玉霓辉石石英钠长石岩、含霓辉石角闪石英钠长石岩、含霓辉石钠长角闪片岩、蓝透闪石石英钠长石岩、镁钠闪石石英钠长石岩等岩石类型。主要组成矿物为硬玉、霓辉石、镁钠闪石、蓝透闪石、镁角闪石、阳起石、石英、钠长石、金红石和榍石。研究表明 ,高压变质峰期后经历了近等温降压退变质过程。
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.
