There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.

Hystrix at 25℃(S. pistillata: 0.0126±0.0045 g/g*day; S. hystrix: 0.0253±0.0081 g/g*day) were significantly higher than those at 28℃(S. pistillata: 0.0066±0.0027 g/g*day; S. hystrix: 0.0083±0.0046 g/g*day) and 20℃(S. pistillata: 0.0058±0.0014 g/g*day; S. hystrix: 0.0047±0.0022 g/g*day).The mean growth rates of S. hystrix in two mesocosms at 25℃ were similar and significantly higher than those of S.

Spinel lherzolites vary from 850°to 1050℃. The number of spinel lherzolite sample increases at 850℃ and decreases at 1050℃ sharply. The rarity of spinel lherzolite between 900° 950℃ has a particular significance. Spinel-garnet lherzolites have higher temperatures (1050° 1100℃) than the spinel lherzolites.
