由于硼(B)在自然界中分布较集中,平均丰度低,而且~(11)B和~(10)B之间质量差大,分馏效应显著,故元素硼及其同位素组成可以作为指相标志来判定硼来源和沉积环境。龙湖钾盐矿区是呵叻高原钾盐矿在老挝境内最主要的矿区之一,ZK309钻孔在龙湖矿区具有代表性。对该钻孔盐岩上覆碎屑层的硼元素及其同位素的分析,B含量56×10~(-6)~103×10~(-6)(wt.%),平均值为73×10~(-6);δ~(11)B的范围为+7.44‰到+11.62‰,平均+8.96‰,介于海水的δ~(11)B值(+39.5‰)及陆相地下水的δ~(11)B值(-3±5‰)之间,B的含量指示中盐段岩盐层沉积后期曾明显有水流体的活动,这种水流体表现出偏向于淡水、咸水混合水特征,而B同位素研究说明粘土矿物的吸附作用是δ~(11)B降低的主要因素。  相似文献

内蒙古哈达贺休盐湖蕴藏着较为丰富的地下卤水资源,但对其成因和演化机制尚缺乏充分的认识。采用稳定同位素方法,研究了哈达贺休盐湖地下卤水及其周边水体的氢氧同位素组成特征,并对卤水的成因进行了分析。结果表明:哈达贺休盐湖地下卤水的δD和δ~(18)O值平均值分别为-0.53 ‰和4.01 ‰,黑河河水的δD和δ~(18)O值平均值分别为-36.73 ‰和-5.51 ‰,居延海湖水的δD和δ1~8O值平均值分别为1.26 ‰和2.73 ‰,当地大气降水的δD和δ1~8O值平均值分别为-5.30 ‰和-1.20 ‰。研究区水体的蒸发趋势线方程为δD=5.32δ1~8O-20.08,该蒸发线偏离全球大气降水线。黑河河水的氘盈余值(d)最大,湖水和地下卤水d的最小,而且湖水和卤水的d值与TDS呈负相关关系。偏正的δD和δ~(18)O值以及较小的d值表明研究区卤水经历了强烈的蒸发,同时还存在与含氧类矿物的同位素交换反应。卤水和居延海湖水氢氧同位素值分布比较集中,并且接近,二者都由黑河河水演化而来。  相似文献

河北坝上地区湖泊沉积物记录的中全新世干旱气候   总被引:13,自引:10,他引:3  
根据位于典型草原带的河北坝上地区白诺尔及毗邻的内蒙古乌兰诺尔湖泊沉积物的K、Na、Ca、Mg等化学元素组成、总有机碳(TOC)与氧同位素(δ18O)的分析,以(K+Na+Ca+Mg)/(Fe+Mn)值指示干旱度,1δ8O值指示夏季风的强弱,TOC值指示湖区植被状况,探讨了该地区14C测年9.8~5.3 ka B.P.以来的气候变化与环境变迁。结果表明:两个剖面所记录的气候变化趋势相近,14C测年7.0~5.7 ka B.P.为偏干期。反映夏季风强弱的氧同位素指标与干旱程度的变化没有明显的对应关系,说明夏季风引起的降水量变化不是气候干湿变化的主要影响因子,温度升高导致的蒸发加强可能对气候干旱化的影响更加明显。  相似文献

综述了柴达木盆地盐湖卤水及其沉积物的硼同位素研究成果,并从pH值、离子浓度、物源补给等几方面对盐湖卤水及其沉积物的硼同位素组成进行了探讨。强烈的蒸发作用可以导致盐湖卤水的pH值降低,从而使δ11B值相应地升高;卤水中的B可能会随碳酸盐的析出而进入到固相中,因此Ca2+浓度和Ca/Cl比值较高的湖泊,其卤水的δ11B值一般都比较高;盐湖卤水及其补给水源的δ11B值与B/Cl比值具有中等程度的负相关关系,这种特性也可以用来指示河水中硼的来源;当易风化的硅酸盐矿物经剥蚀迁移并最终在湖泊中沉积时,盐湖沉积物的δ11B值会因这些低δ11B值的物源加入而变低;此外,强烈的化学风化会使湖泊中沉积较多的细粒粘土矿物,由于粘土矿物的吸附作用也会使得盐湖沉积物中的δ11B值偏低。关于柴达木盆地盐湖硼同位素的研究,不仅可以为盐湖的形成、演化及成盐成矿规律的研究提供可靠依据,而且可以为盐湖资源评价及合理开发提供科学依据。  相似文献

基于对福建屏南仙山泥炭沉积物中物理化学性质十分稳定的α-纤维素的提取及其碳同位素分析,重建了研究区距今1 400 a以来的气候演化历史。研究结果显示:仙山泥炭钻孔中α-纤维素δ13C值的变化范围为-26.6‰~-11.3‰,其大幅度的波动特征主要与区域降水控制的盆地沉积环境变化有关,当降水偏多时盆地积水形成类似湖泊的水下沉积环境,沉积物中有机质主要来源于δ13C值偏重的沉水植物;反之则以δ13C值偏轻的沼泽植物为主。依据AMS14C测年的结果,距今1 400 a以来研究区经历了气候偏湿(AD 600~910年)-偏干(AD910~1640年)-偏湿(AD 1640年至今)3个变化阶段。在数十年至百年时间尺度上,纤维素δ13C记录中出现的降水减少时期与太阳活动极小期(中世纪极小期、欧特极小期、沃夫极小期、史波勒极小期、蒙德极小期和道尔顿极小期)一一对应,两者呈现正相关关系,揭示太阳活动的减弱是控制研究区降水减少的主要因素,为预测区域降水变化趋势提供了依据。  相似文献

湖积物中不同无机碳酸盐矿物常常混杂在一起,其氧同位素组成(δ18O)差异会影响碳酸盐δ18O环境信息提取的可靠性。不同矿物之间δ18O差值明显且幅度不一。20~25℃时生成的白云石比共生的方解石富集18O可能为0‰~9‰不等,亦或方解石比白云石可能更富集18O达0‰~12.3‰。常温状态,相同条件下形成的文石δ18O值较方解石高出0‰~1‰,或者方解石较文石δ18O值高出0‰~4.47‰。镁方解石中MgCO3的mol百分含量每增加1%,其δ18O值相对于纯方解石δ18O值增加0.06‰~0.17‰。在利用碳酸盐δ18O进行气候及环境研究时,不能根据某种差值进行校正,而应进行单矿物测试。由此,对不同无机碳酸盐矿物的分离及同位素测试、推算方法进行了归纳和述评。  相似文献

深入探讨了柴达木盆地盐湖区土壤黑碳分布及土气交换特征。研究结果显示,研究区土壤总黑碳含量范围为0.50~6.79 g/kg,平均值达到1.64 g/kg;土壤烟炱组分黑碳含量范围为0.50~4.75 g/kg,平均值达到1.144 g/kg;气溶胶黑碳含量范围为0.34~4.92μg/m~3,平均值达到0.98μg/m~3。柴达木盆地盐湖区盐湖资源的大量开采和工业化生产等可能造成该地区黑碳大量排放。盐湖区土壤黑碳稳定碳同位素值(δ~(13)C_(BC))在-25.33‰~-23.46‰之间变化,平均值为-24.21‰,表明该地区土壤黑碳来源可能受C_3植物和化石燃料来源的共同影响。首次运用逃逸系数探讨了柴达木盆地盐湖区黑碳土气交换行为,结果表明研究区黑碳土气交换行为确实存在,但存在一定程度的模拟不确定性。  相似文献

青海湖是我国内陆最大的闭流型水体,地处东亚季风和西风的交汇影响区,对区域降水的改变等气候变化反应敏感,其水位变化历史是研究区域季风环境演变极其宝贵和重要的环境档案。青海湖Q14B孔岩芯介壳δ18Oc变化曲线自1991年发表以来,受到国内外同行的广泛关注和继续探讨。依据近年来青海湖气候与环境演变研究的最新研究结果和个人对闭流型湖泊同位素地球化学的认识,对介壳δ18Oc变化曲线进行了重新判读并得出以下结论:14.5~10.5 ka B.P.,青海湖区气候已逐渐从干冷向温湿过渡,季风降水逐渐增加;10.8~10.5 ka B.P.,青海湖处于碳酸盐滩湖环境,湖水深度从几米演变到接近干涸;10.5~9.5 kaB.P.,季风降水增加;9.5~8 ka B.P,湖水位从此前的接近干涸演变到此间的2~8 m,δ18Oc值跌落到一个较低的位置;8~3.5ka B.P,气候条件相对稳定,湖水不断蒸发引起重同位素的富集;3.5~0ka B.P,湖水处于同位素稳定阶段。研究结果还显示,δ18Oc值的短期波动与湖泊水位短期变化关系密切且明显,即水位高低分别对应δ18Oc的低值与高值。δ18Oc值的长期变化与湖泊水位长期变化关系不明显,水位较浅时,二者几乎无关联;水位较深时,水位的长期缓慢下降自然会导致δ18Oc逐渐攀升,而水位的长期缓慢上升也可以伴随δ18Oc逐渐攀升。  相似文献

对柴达木盆地东部尕海湖DG03孔岩芯沉积物的粒度特征的研究,结果表明:在12 800—11 800 cal a BP之间,DG03孔沉积物主要以砂为主,含少量的粉砂和粘土,表明钻孔地点的水动力条件比较强,湖泊水位较低,尕海地区经历了一次短暂的干旱事件,这一事件可能是该区域对全球性的YD事件的响应;全新世早中期(11 800—5 600 cal a BP),沉积物主要以粉砂和粘土为主,钻孔地点的水动力条件比较弱,湖泊水位较高,气候环境相对湿润;全新世中晚期以来(5 600 cal a BP以来),沉积物中砂粒组分含量越来越多,粉砂和粘土含量越来越少,平均粒径越来越大,钻孔地点的水动力越来越强,该区域经历了一个干旱化的过程。  相似文献
