塔里木-中朝板块北缘的志留纪岛弧公婆泉群火山岩地质地球化学及构造意义

公婆泉群位于北山中部，可分为：北、南两带。南带为弧后盆地玄武岩-安山岩组合，北带为岛弧火山岩组合，西段窑洞努如为火山角砾岩和熔火山角砾岩组合，中段公婆泉一带为玄武岩-安山岩-流纹岩-粗面岩组合，东段东七一山地区为玄武岩-安山岩-流纹岩组合。岩石组合，地球化学综合分析认为，公婆泉群是中-晚志留世哈萨克斯坦板块俯冲与塔里木-中朝板块的产物。岛弧西段窑洞努如位于近大陆或者在水下陆壳。公婆泉位于近海沟陆壳，而东七一山则远离海沟，是在洋壳的基础上发育的。说明塔里木-中朝板块是一个统一的板块，同时在早古生代存在哈萨克斯坦板块向塔里木-中朝板块的俯冲。     

采用4,6-二氨基间苯二酚-对苯二甲酸盐合成聚苯撑苯并二噁唑

以4，6-二氨基间苯二酚盐酸盐和对苯二甲酸为原料，制备了4，6-二氨基间苯二酚-对苯二甲酸盐(TA盐)，并采用傅里叶红外(FTIR)、质谱(MS)、差热分析(DSC)和元素分析等测试手段对其结构进行了表征；以多聚磷酸为介质，将TA盐缩聚得到具有较高粘度(特性粘数[η]＝24．5dL／g)的聚苯撑苯并二恶唑(PBO)，并通过FTIR、元素分析和热重分析(TGA)等对PBO合成工艺和热性能进行了研究．这种通过TA盐聚合的方法不仅缩短了反应时间，而且比较容易得到具有较高相对分子质量的PBO．

松辽盆地成藏过程和成藏动力系统

随着全球范围内沉积盆地油气勘探程度的提高，用更有效的方法勘探油气藏已成为必然。作者引入系统论的方法，在研究了松辽盆地地球动力学背景、盆地构造、盆地沉积、热史等盆地流体动力条件的基础上提出了流体势及流体压力计算、新增剩余压力计算模型、古流体压力恢复等恢复古沉积环境及流体动力研究的计算模型。在动态研究油气藏方面做了初步探讨。     

松辽盆地南部海坨子地区油气成藏研究

松辽盆地南部海坨子地区扶余油层与萨尔图油层中有机包裹体有较大差异。扶余油层中有机包裹体量多 ,个体大 ,早期和晚期有机包裹体发出强的黄色荧光 ;萨尔图油层有机包裹体丰度不高 ,个体都较小 ,早期和晚期有机包裹体发出弱的浅黄色荧光。这说明萨尔图油层的烃类成熟度比扶余油层的烃类成熟度高。海坨子构造主要发生过两次成藏过程 ,早期在嫩江期末 ,晚期发生在明水期末至第三纪。扶余油层和萨尔图油层的油气来源不同 ,前者油气主要来自海坨子构造青一段烃源岩 ,后者主要来自乾安凹陷青山口组烃源岩。

Holocene lake deposits of Bosten Lake, southern Xinjiang, China

A 9.25-m-long sediment core from Bosten Lake,Xinjiang, provides detailed information about changes in the water budget and biological acticity over the last 8400 cal-endar years. The chronology is constructed from six AMS radiocarbon dates on the terrestrial plant remains. Based onanalyses of TOC, CO3, detrital compounds and biogenic SiO2,lake level fluctuations and periods of remarkably-negative water budget appeared at 8.4-8.2 cal ka, 7.38-7.25 cal ka,5.7-5.5 cal ka, 3.7-3.4 cal ka and 3.3-2.9 cal ka, respec-tively. As they are in-phase with low lake levels at Sumxl Co and Bangong Co in western Tibet Plateau and with paleo-lakes in Inner Mongolia, a climate-induced change to some-what drier and warmer conditions is inferred. A further drop in lake level after 1320 AD of about 200 yr duration may heattributed to a negative water balance prior to the main phase of the Little Ice Age. Deep and stable lake phases of 1500 yr and 1800 yr duration at 7.2-5.7 cal ka and 5.5-3.7cal ka coincide with maximum moisture during the Holocene Megathermai in China. The long term trend towards aridity since about 4.3 cal ka can dearly be recognised. The reduced water budget of Bosten Lake from 640-1200 AD may be attributed to local effects.     

Evolution of the South China Sea and monsoon history revealed in deep-sea records

As the third summary report of ODP Leg 184 to the South China Sea (SCS), this paper discusses the evolution of the East Asian monsoon and the SCS basin. A multi-proxy approach, involving geochemistry, micropale-ontology, pollen and other analyses, was adopted for reconstructing the evolutionary history of the East Asian monsoon, which was characterized by a series of paleo-climate events especially at 8, 3.2, 2.2 and 0.4 Ma. The new record indicates similar stages in the development of the East and South Asian monsoons, with an enhanced winter monsoon over East Asia being the major difference. The rich spectrums of monsoon variability from the southern SCS also reveal other characteristic features of the low latitude ocean. Evidence for the evolution of the SCS includes the hemipelagic Oligocene sediments, implying the existence of deep water environments during the early seafloor spreading stage of the SCS basin. The four major unconformities and some remarkabl ediagenetic features in upper Oligocene deposits indicate the strongest tectonic events in the region. From a careful comparison of lithologies and sedimentation rates, we conclude that the prominent differences in sedimentary environments between the southern and northern SCS were established only by ～3 Ma.
