A huge oceanic-type UHP metamorphic belt in southwestern Tianshan, China: Peak metamorphic age and P-T path

Recent progress in the study of the UHP metamorphic belt in southwestern Tianshan, China, is summarized in this paper. This about 80-kin-long and over 10-km-wide UHP belt has been recognized by the discovery of coesite, coesite pseudomorphs and other UHP minerals. It is the largest oceanic-type UHP metamorphic belt reported so far. It has formed due to northward subduc- tion of the Tianshan Paleo-Ocean. U-Pb dating of metamorphic rims of zircons from a coesite-bearing garnet-phengite schist yields a peak UHP metamorphic ages of 320±3.7 Ma. Combined with ages of 233-226 Ma obtained from rims of zircons from retrograded eclogites, a long retrograde metamorphic evolution （〉70 Ma） has been revealed. According to phase equilibria mod- eling, the P-T paths of both coesite-bearing eclogites and garnet-phengite schists are characterized by thermal relaxation, i.e., the metamorphic temperature peak lags behind the pressure peak, indicating that the UHP rocks experienced slow and long heating and decompression during exhumation in the subduction channel. On the basis of the field observation that a small amount of eclogite lenses is wrapped in large volumes of metapelites, and the similar P-T paths of both rock types, we propose that the ex- humation of the UHP eclogites from southwestern Tianshan, China, may have resulted from the exhumation of large volumes of low-density metapelites, which carried the denser eclogites to the Earth＇s surface.     

2012年西南大西洋公海阿根廷滑柔鱼产量分布与表温关系研究

根据2012年1-4月我国鱿钓船西南大西洋公海阿根廷滑柔鱼资源探捕数据,结合历年调查资料和表温资料,对其产量分布与表温关系进行分析.结果显示:2012年西南大西洋阿根廷滑柔鱼产量主要集中在1、2两个月份,占探捕调查总产量的65.2％,其中产量最高的月份为2月份,CPUE达7.93 t/d;在适温范围内CPUE与SST之间具有较高的相关性,表现为CPUE随SST值升高而增大;从1-4月探捕海区情况来看,中心渔场渔区主要集中于45.25°-47.25° S,60.00°～60.75° W之间,随着时间的推移,中心渔场有自北向南移动的趋势.

Climatic significance of n-alkanes and their compound-specific δD values from lake surface sediments on the Southwestern Tibetan Plateau

The content and hydrogen isotope ratios of n-alkanes extracted from recent lake surface sediments sampled from nine lakes in three different climate zones on the Southwestern Tibetan Plateau were analyzed. Values were compared with n-alkanes in plants from lake drain- ages, and δD values of meteoric water, lake water, and mean annual precipitation. The results showed that n-C23 was predominantly derived from aquatic plants, and n-C27- n-C33 from terrestrial higher plants. The average carbon chain length of n-C27-n-C33 （ACL27-33） was positively correlated with the mean annual precipitation. δD values of the long-chain n-alkanes n-C29 and n-C31 of terrestrial origin （varying between -214‰ and -169 ‰, and-226 ‰ and -185 ‰, respectively） were inversely correlated with mean annual precipitation; but in accordance with the average annual variations in δD （OIPC）, δD values of n-C31 were strongly related to the δD values of growing season meteoric water （R2 = 0.74）. The large difference between δD values of n-C23 of aquatic origin and n-C31 （an average of about 27 ‰） demonstrates the enrichment of the lake water δD compared to precipitation, caused by strong evaporation in the semiarid-arid areas of the southwestern Tibetan Plateau. Average value of εn-c25- 31/p （-95 ‰） is evidently higher than the value observed in European wet regions （-128 ‰）; besides, εn-C31 （about -116 ‰） is constant along the study transect （SD = 9）, which indicates that n-C31 is a useful proxy for the environment.

渤海海域庙西北洼烃源岩芳烃地球化学特征

通过对渤海海域庙西北洼古近系17个烃源岩样品的色谱-质谱分析,系统研究了渤海海域烃源岩的芳烃地球化学特征,并进行了烃源岩沉积环境与成熟度的分析.结果显示:研究区烃源岩样品中检测到的芳烃化合物有170余种,以萘、菲系列化合物为主,不同层段烃源岩芳烃各系列化合物相对含量略有差异.烷基萘及三芴系列化合物分析表明东营组第二段烃源岩沉积时水体还原性较弱,沙河街组第一段烃源岩沉积时水体还原性最强,东营组第三段次之.烷基萘和三芳甾烷参数表明烃源岩样品现今主要处于成熟阶段.
