2Ductile deformation within Upper Himalaya Crystalline Sequence and geological implications,in Nyalam area,Southern Tibet显示文摘The South Tibet Detachment System(STDS) is a flat normal fault that separates the Upper Himalaya Crystalline Sequence(UHCS) below from the Tethyan Sedimentary Sequence(TSS) above.Timing of deformations related to the STDS is critical to understand the mechanism and evolution of the Himalaya collision zone.The Nyalam detachment(ND)(~86°E) locates in the middle portion of STDS(81°-89°E).Dating of deformed leucocratic dykes that are most probably syntectonic at different depth beneath the ND,allow us to constrain the timing of deformation.(1) Dyke T11N37 located ~3500 m structurally below the ND emplaced at 27.4± 0.2 Ma;(2) Dyke T11N32 located ~1400 m structurally below the ND emplaced at 22.0±0.3 Ma;(3) T11N25 located within the top to the north STD shear zone,~150 m structurally below the ND,emplaced at 17.1±0.2 Ma.Combining ND footwall cooling history and T11N25 deformation temperature,we indicate a probable onset of top to the north deformation at ~16 Ma at this location.These results show an upward younging of the probable timing of onset of the deformation at different structural distance below the ND.We then propose a new model for deformation migration below the ND with deformation starting by pure shear deformation at depth prior to ~27.5 Ma that migrates upward at a rate of ~ 0.3 mm/a until ~18 Ma when deformation switches to top to the north shearing in the South Tibet Detachment shear zone(STDsz).As deformation on the ND stops at 14-13 Ma this would imply that significant top to the North motion would be limited to less than 5 Ma and would jeopardize the importance of lower channel flow.LIU XiaoBing LIU XiaoHan LELOUP P.H.

4Chinese life cycle impact assessment factors显示文摘The methodological basis and procedures for determination of Chinese normalization references and weighting factors according to the EDIP\|method is described. According to Chinese industrial development intensity and population density, China was divided into three regions and the normalization references for each region were calculated on the basis of an inventory of all of the region’s environmental emissions in 1990. The normalization reference was determined as the total environmental impact potential for the area in question in 1990 (EP(j) 90 ) divided by the population. The weighting factor was determined as the normalization reference (ER(j) 90 ) divided by society’s target contribution in the year 2000 based on Chinese political reduction plans, ER(j) T2000 . This paper presents and discuss results obtained for eight different environmental impact categories relevant for China: global warming, stratospheric ozone depletion, acidification, nutrient enrichment, photochemical ozone formation and generation of bulk waste, hazardous waste and slag and ashes.Yang, J.-X.

5湘中泥盆-石炭系界线划分的新进展显示文摘中国的泥盆-石炭系界线研究历时已久,其传统的下石炭统剖面位于贵州省独山城南五里桥与黑石关村之间.俞建章(1931)在此曾建立2个珊瑚带:下部革老河组Cystophrentis带和上部汤耙沟组Pseudouralinia带,并将以上两个珊瑚带与英国Avon Gorge剖面的Z带与C带进行对比,认为中国南部泥盆—石炭系界线划在Cystophrintis带底.1965年。方晓思 P.H.司蒂曼斯 M.斯蒂尔 1993科学通报1993,38,8:10
67~Be: A Geochemical Tracer for Seasonal Erosion of Surface Soil in Watershed of Lake Hongfeng, Guizhou, China显示文摘7Be penetrative depth in undisturbed surface soil is within 4mm.^7Be activity shows exponential decrease with soil depth,which is expressed as a diffusion process.7Be penetrative depth in undisturbed surface soil is apparently deeper in the fall (0.22-0.37g cm^-1) than in the spring (0.11-0.28g cm^-2) at the same site;Whereas,^7Be apparent activity at the top of surface soil is higher in the spring (0.3-2.2Bq g^-1)than in the fall (0.2-0.5Bqg^-1) at the same site,The 7Be inventory(189-544Bq m^-2)changes with both locations and seasons.Although the ^7Be flux to the earth's surface increases with amount of precipitation,its maximum inventory in the soil profiles decreases to 30%-40% after the rainy period.Calculated by the diffusion equation,the erosion and accumulation rates of soil particles are agreeable with the observation in situ,Which shows that the rates in fall are 1.5 times those in spring.The eroded soil particles almost all have been removed on the tablelands rathel than transported into the drainage system.This indicates that the soil erosion process in the karst region is only partial transportation within a short distance.BAI ZHANGUO WAN GUOJIANG WANG CHANGSHENG WAN XI HUANGRONGGUI P.H.

8藏南聂拉木高喜马拉雅结晶岩系上部韧性变形年代学及地质意义显示文摘藏南拆离断层系(STDS)为低角度正断层,其上盘为特提斯喜马拉雅沉积岩系,下盘为高喜马拉雅结晶岩系.厘定与STDS有关的变形时限,对深入理解喜马拉雅造山带的变形机制与构造演化具重要意义.聂拉木拆离断层(ND)(86°E)位于STDS中段(81°~89°E),ND下盘不同构造位置(即采样点位与ND的构造距离)的变形花岗质岩脉具有一定程度的同构造特征,锆石-独居石U-Th/Pb年龄可以不同程度地厘定变形时间:(1)样品T11N37(ND下盘约3500m构造位置)的侵位年龄为27.4±0.2Ma;(2)样品T11N32(ND下盘约1400m构造位置)的侵位年龄为22.0±0.3Ma;(3)样品T11N25(ND下盘约150m构造位置)的侵位年龄为17.1±0.2Ma,结合ND下盘冷却历史和T11N25变形温度,认为其变形最晚开始时间约为16Ma.年代学结果表明,变形作用的最晚开始时间由下盘往拆离面逐渐变年轻.因此提出ND下盘变形迁移的新模式,即ND下盘在约27.5Ma之前开始纯剪切为主的变形作用,随后变形以约0.3mm/a的速率向拆离面移动,并于约18Ma在藏南拆离断层剪切带(STDsz)底部转化为简单剪切变形为主.由于ND变形结束于14~13Ma,这意味着北向剪切作用的持续时限小于约5Ma,对下地壳流动模型提出新的挑战.刘小兵 刘小汉 LELOUP P.H.

9EFFECTS OF CARBON CONTENT AND ROLLING PROCESSING ON RETAINED AUSTENITE FOR HOT-ROLLED TRIP STEELS显示文摘The effects of finishing rolling temperature and coiling temperature on retained austen-ire were studied for hot-rolled transformation induced plasticity (TRIP) steels withdifferent carbon content. The experimental results showed that an appropriate volumefraction of retained austenite from 6% to 11% could be obtained according to the dif-ferent carbon content less than 0.20% by controlled finishing rolling and coiling forthe hot-rolled TRIP steels. It can be concluded that carbon content has a significanteffect on the fraction of retained austenite and coiling processing plays stronger roleon retaining austenite than fishing rolling processing.Y.

10保罗·K.费耶阿本德显示文摘保罗·费耶阿本德于1924年1月13日生于维也纳。他于1994年2月11日,在他刚过完他的70岁生日不到一个月之后,由于一种不宜动手术的脑肿瘤而在瑞士法语区热诺里尔去逝。 费耶阿本德的生长环境并不富裕。他有着多方面的兴趣,是个非常优秀的、有求知欲的学生。还在他上中学时,他就仔细研读了大学水平的数学、物理和天文学教科书。他终生不渝的对音乐的热爱在年轻时就已完全显露出来:他弹手风琴,上小提琴课,喜爱歌剧,他还在一个混合合唱队中唱歌,后来他在音乐学院上了声乐课。1942年春中学毕业后,费耶阿本德首先被征招进青年义务劳动军(奥地利在1938年被“补充进”德意志帝国),1942年底他又应征入伍。他参加了许多前线作战,在1945年1月的一次作战中被一颗机枪子弹击中脊柱,从此他的髋部以下就瘫痪了。在长期使用轮椅以后,他终于又可以拄着拐杖走路了。他一生都忍受着阶段性出现的巨大疼痛的折磨,在许多公开场合露面时,他都是靠大盒的止疼药熬过去的。他却从来没对此大事声张,他的自传里也很少有这方面的叙述。P.H.洪纳 王彤 1998世界哲学1998,,1:4
