博格达山南缘芦草沟组的浊积扇

根据岩性、沉积构造、古生物化石和地球化学标志，系统分析了博格达山南缘广泛发育的二叠系芦草沟组的沉积环境。研究表明：博格达山南缘芦草沟组深湖相沉积十分发育，并在此背景上沉积了近岸浊积扇和远岸浊积扇。其中，深湖相暗色泥、页岩和油页岩构成了良好的烃源岩。同时，认为吐哈盆地前侏罗系具有良好的勘探前景。

Research on the disappearance causes of the Tenghualuo Site in Lianyungang,Jiangsu Province, China

With brilliant civilization during the transitional period from a original clan society to a state society in prehistory,the Neolithic Tenghualuo Site in Lianyungang was discovered by archaeological survey in 1989,which was titled as‘one of the nation’s ten great archeological discoveries in 2000’.However,the transgression and the anthropogenic environment deterioration have ever been employed to explain the abandonment of the site.Based on a dynasty framework established by the 14 C dating,and using the experimental methods such as micro-paleontology identification in foraminifera and charophytes, the content test of Rb and Sr,susceptibility analysis as well as granularity and sedimentary facies analysis,some researches on the sediments from the two exploration layers at Tenghualuo Site were conducted,and the following new findings have been gained:Firstly,foraminifera which are relevant to the marine environment were not found in the sediment layer,however,25 charales,which usually live in the freshwater environment,in 07LTT1 exploration samples were found.Among them,3 charales were found in the samples from the forth sediment layer below the late Longshan Cultural layer and 22 charates were from the second sediment layer above the late Longshan Cultural layer.Furthermore,5 plant seeds and 41 fungal spores,together with many carbonation holes,plant seed shells,as well as their roots and stems were also found in the second sediment layer above the late Longshan Cultural layer.Secondly,the cumulative probability curves of the sediments’granularity in both the last and its overlying culture intermittent layers have characteristics of three-phase river sediment curve,and the ratios between Rb and Sr are both quite high in samples from two layers sedimented during the disappearing time of the site.All above-mentioned evidences indicate that disappearance of the Tenghualuo Site was not related to the transgression.The late Longshan Culture of the site could be completely abandoned after a relatively long-ter     

岩石破裂失稳的前兆规律研究

提出用“两体作用”模型来研究自然界的岩体破裂换稳现象。具体分析了两冉体作用系统的失稳过程，运用微机差分计算获得了它的变形和声发射前兆规律。最后在文献［１］的声发射序列关系中引入了距离因子和随机因子，发现有些序列中出现的声发射活动相对平静是由于在两岩体相互作用过程中某一岩体弹性恢复所致。     

黄龙洞沉积的环境意义及旅游开发评价

对洞穴沉积物岩性进行分层描述 ,并取样进行了 C1 4、热释光及孢粉鉴定 ,确定沉积物时代为距今 1 4630± 1 90年～ 85 5 0± 75年 .岩性和孢粉组合特征显示洞内沉积经历了暖湿、温干、暖湿、再到温干的气候变迁 ,其生态环境属于稀树草原型 .通过与本区域周边地区 (临汾盆地、北京平原地区 )孢粉组合对比 ,判断黄龙洞所在太原盆地北部山区气候、生态环境及其变化趋势与我国北方地区大体是同步的 ,同时也存在一定差异 .
