夕线石

Those sillimanites can not indicate high temperature (corresponding to the temperature of high amphibolite facies) condition.

区内只有少数粗大的针柱状夕线石可能代表高温条件下由纤维状矽线石重结晶所成，具有指示意义。

It is the deformation-metamorphism process under pressure and temperature condition, not the original rock composition, that controls the presence of sillimanite.

研究区内夕线石片麻岩的形成主要与黑云斜长片麻岩有关，影响夕线石出现的决定性因素是特定温压条件下的变形变质改造过程，而不是原岩成分。

The iron replacement of sillimanite may somewhat affect the physic-chemical calculation and exert negative effects on sillimanite mineralization.

铁组分的类质同像替换对物理化学计算和夕线石矿化环境均有所影响，对夕线石晶胞参数a的影响很小，而对b，尤其对c的影响较大，与前人的结论有所不同。

With the decreasing temperature, the solubility of the other components in sillimanite decreased and most of the dissolved components were exsolved, resulting in the formation of the exsolution texture.

南极拉斯曼丘陵长英质片麻岩中的粗粒夕线石可能有内部出溶现象，出溶形成的矿物有磁铁矿、钛铁矿-赤铁矿和石英出溶矿物条纹，并有少量的斜方辉石。

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。

The medium-pressure kyanite sequence metamorphic belt includes biotite zone, garnet zone, staurolite zone, kyanite zone, sillimanite zone and partial melting migmatites.

黑云母带为450-530℃、0.45-0.7GPa，石榴石带为550-570℃、0.55-0.75GPa，十字石带可能为602±15℃、0.67±0.16GPa，十字石带后期变质条件为515℃、0.4GPa，夕线石带为678.7℃、0.6±0.05GPa，混合岩中浅色脉体为750～800℃、0.9～1.0GPa。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
