山西代县金红石矿床的含矿岩石按岩石中矿物组成可以划分以下几种类型：阳起直闪岩、直闪阳起直闪岩、石榴石阳起直闪岩、十字石阳起直闪岩、阳起黑云直闪岩、阳起直闪岩、蓝晶石直闪岩、滑石阳起直闪岩、绿泥阳起直闪岩等。按金红石的颜色可以划分为两类，即红色金红石矿石、黑色金红石矿石。

This variety is called "Chiastolite"(named after the Greek word for cross) and sometimes referred to in ancient texts as "Lapis Crucifer", meaning "Cross Stone" or "Macle".

这类晶体被称之为"空晶石"，在古籍中也称之为"十字石"，意为有十字图案的石头或有斑点的石头。

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。

Andalusite-sillimanite type progressive metamorphic belt composed of chlorite-biotite zone, biotite-garnet zone, garnet-staurolite zone, staurolite-andalusite zone and sillimanite zone in Aletai Xinjiang is studied. According to the component zoning of the garnets, the relationship between metamorphism and deformation, and the paragenetic association evolution of the minerals, etc, the metamorphism is divided into three evolution stages: the stage before peak metamorphism, the peak metamorphism stage and the stage after peak metamorphism.

Of the five stages deformation, the exact ages of the (2) and (3) were determined by 40Ar/39Ar method as 290 and 259 Ma respectively.2. New results on the metamorphic belts and associated metamorphism of the Xiaopu metamorphic rocksBased on detailed microtextural observations and occurrence of typical metamorphic minerals, five metamorphic belts in the Xiaopu metamorphic rocks are identified. From the north to the south, they are biotite belt, garnet belt, staurolite belt, andalusite belt, and sillimanite belt. I suggested that the metamorphic belts occurred in the Xiaopu area belongs to the high temperature/low pressure series, may have resulted from the later Permian crust extension at ca. 290 Ma.3. I suggest that there may have been a Carboniferous backarc basin along the southern slope of the Harlik Mountain.Detrital Zircon SHRIMP U-Pb dating indicated that the sedimentary age of the Julideneng formation lithic sandstone must be later than late Devonian, most likely is Carboniferous rather than previously thought Precambrian. Analyses on its geologic setting, location of provenance, and sedimentary environment suggest the Carboniferous strata may form in a lagged backarc basin bounded by backarc uplifts.5. Reconstruction of the post-Paleozoic tectonic evolution history of the Harlik MountainThe tectonic evolution of Harlik mountains since the Paleozoic were reconstructed as followings:(1) arc-affinity magmative activities occurred during the middle-Ordovician to early-Silurian;(2) the middle-Silurian to late-Devonian was a back-arc uplift stage;(3) back-arc extension featured the Carboniferous period;(4) post-collisional extension and/then compression during Permian;(5) at the Mesozoic, differential uplift developed; and (6) the late Cenozoic is the intra-continental re-orogen stage.6. Primary estimation of the crust shortening is madeThe folded pre-Mesozoic strata were used to estimate crust shortening along the Harliknanshankou-Koumenzi, Shichengzi-Baishitou, and Qincheng-Xiaopu sections. Their shortening ratios are 16.2%, 19.8%, and 20.1% respectively corresponding crust shortening are 4.3, 9, and 11.3 km.

The experimental results show that the unit-cell parameter β is continuously increasing with increasing pressure, suggesting the decrease of structural symmetry of staurolite. An unknown phase transition in staurolite structure was also observed in the pressure range of 1.5~2.7 GPa.

实验表明，在实验压力范围内，随着压力的增加晶胞参数β值逐渐增大，表明了十字石的结构对称性随压力增加而有所降低；同时，在1.5~2.7GPa压力范围内，十字石的晶体结构也发生了改变。
