The low-pressure andalusite sequence metamorphic belt includes biotite zone, garnet zone, staurolite zone, staurolite-andalusite zone, sillimanite zone and cordierite-sillimanite zone. It is calculated that the P-T conditions are 445~550℃, 0.2~0.6GPa for biotite zone, 480~566℃, 0.54± 0.22GPa for the garnet zone, 601±20℃, 0.8±0.25GPa for the staurolite zone, 540±20℃, 0.32± 0.05GPa for the staurolite-andalusite zone, 640℃, 0.43GPa for sillimanite zone, 740~800℃, 0.4~0.7GPa for the cordierite-sillimanite zone.
黑云母带的变质条件估计在445~550℃、压力在0.2~0.6GPa范围变化;石榴石带温度在480~566℃、压力在0.54±0.22GPa的范围;十字石带范围为601±20℃、0.8±0.25GPa;十字石-红柱石带为540±20℃、0.32±0.05GPa,而利632.4℃、0.785GPa,这个值不是红柱石的稳定范围,这可能是其早期中压变质条件;矽线石带的条件640℃、0.43GPa左右,由于其石榴石中有蓝晶石包体,因此其早期也可能有中压条件的变质;堇青石-夕线石带范围大致为740~800℃、0.4~0.7GPa之间。

Three important conclusions are as follows:(1) the H2O content in garnet and omphacite can be up to 2000ppm and 3000ppm by weight respectively, indicating that they are significant carrier recycing surficial water into deep earth;(2) the heterogeneous distribution at the small scale of the H2O content and hydrogen isotopic ratios suggest that the whole subduction- exhumation process should be very fast;(3) the regular decrease of H2O content from rim to core within some garnet and omphacite grains indicates that hydrogen diffused out from mineral lattice during exhumation in response to sharp pressure decrease, and such hydrogen is expected to be involved in the early-stage retrograde metamorphism.
取得的主要科学认识包括:(1)石榴石和绿辉石的结构水含量可以分别高至2000ppm和3000ppm,这表明它们是板块俯冲过程中将地表水携带进地球深部的重要载体;(2)水含量和氢同位素组成表现出小尺度的不均一分布,说明板块的俯冲和折返过程是十分快速的;(3)在板块折返的早期,由于压力的降低,矿物中的H 会发生不同程度和尺度的扩散,这是早期退变质流体的重要来源。
