1博斯腾湖碳酸盐和同位素组成的全新世古环境演变高分辨记录及与冰川活动的响应显示文摘本文通过对在新疆南部塔里木盆地北缘博斯腾湖采集的一根953cm的岩心进行了早全新世以来的古气候重建。对BSTC2000岩心进行了碳酸盐矿物组成、Ca/1000Sr,有机质TOC,C/N和C/S分析,并结合BSTC2000岩心附近的一个沉积物剖面的孢粉资料,利用多指标重建了8500aBP以来的古气候变化特征。在2个平行岩心中对保存的植物叶片、草籽,以及全有机质进行了9个AMS14C年代测定。8500~8100aBP气候冷湿,钻孔位置为河流-滨湖相环境,沉积物中有3层泥炭层。从8100~6400aBP,气温升高,湖泊扩张,气候暖湿,湖泊可能为最高湖面时期。而从6400~5100aBP湖泊稍微下降,气候变冷。在中全新世晚期从5100~3100aBP气候变得高温干旱,但其间的4400~3800aBP有短暂的气候变冷,早期大量的冰雪融水补给博斯腾湖,使得湖泊水位上升。湖泊的第二个高湖面期是5200~3800aBP。在3100~2200aBP气候冷湿,由于蒸发减弱而湖泊有所扩张,湖泊在3100至2800aBP期间是最后一次短暂的高湖面期。这次短期高湖面后,湖泊由于较长时期的低温而引起的供水减少,湖泊收缩。从2200~1200aBP,气候变得干热,湖泊收缩。尽管从1200aBP以来,温度有所下降,气候变得暖干,湖泊又开始有所上升,但是没有达到博斯腾湖出水口孔雀河的海拔高度。张成君 郑绵平 A PROKOPENKO M STEFFEN 匡娟 杨奇丽 郭方琴 冯兆东 2007地质学报2007,81,12:25
2Carbon and Oxygen Isotopic Composition of Surface-Sediment Carbonate in Bosten Lake (Xinjiang,China) and its Controlling Factors显示文摘博斯顿·莱克是有在 Tianshan 山融化冰和雪主要供应的水的一个中间纬度的湖。湖的 depositional 环境是空间地由于在湖的西方的部分的主要入口和单个插头的最近不一致。分析结果证明最近的湖沉积的同位素的作文与这特定的湖的 depositional 环境有关并且到结果的碳和氧焦化矿物学。在在 Kaidu 河入口和 Kongqi 河插头之间的西南的湖区域,碳同位素作文(δ 13 C )碳酸盐沉积的价值( −1 ‰ 到 −2 ‰)没有关系到碳酸盐的氧同位素作文(δ 18 O )价值( −7 ‰ 到 8 ‰),与显示出低可变性的两同位素。碳酸盐内容是低的(<20%) 。X 光检查衍射分析的碳酸盐矿物质主要由方解石组成,当霰石没被记录时。湖水的咸度在由于 Kaidu 河流入的河口区域是低的。在比较,碳和氧同位素价值在湖的中间、东方的部分是更高的,与 δ 13 C 价值在之间近似 +0.5 ‰和 +3 ‰,和 δ 18 在 −1 ‰和 −5 ‰之间的 O 价值。在稳定的氧和碳同位素之间有中等关联,与约 0.63 的关联 r 的一个系数。这暗示湖水有一相对短的住处时间。碳酸盐矿物质在湖的中间、东方的区域组成方解石和霰石。霰石和 Mg 方解石在更高的湖水咸度和温度被形成,并且更大的蒸发完成。在在水和相关的碳和氧同位素珍视的大气的公司 2 原因之间的湖和提高的同位素的平衡的中间、东方的区域的更盐的湖水为霰石和 Mg 方解石决定了。蒸发和生物过程是为咸度和在博斯顿·莱克的表面沉积碳酸盐的碳酸盐矿物学影响的主要原因。在空气和水身体之间的湖水住处时间和 CO 2 交换控制碳和碳酸盐沉积的氧同位素作文。另外,有机物污染和分解导致湖表面沉积碳酸盐的反常地低的碳同位素价值。Steffen MISCHKE Alexander PROKOPENKO 2009Acta Geologica Sinica(English Edition)2009,83,2:14
3High-Resolution Records of the Holocene Paleoenvironmental Variation Reflected by Carbonate and Its Isotopic Compositions in Bosten Lake and Response to Glacial Activities显示文摘The Early Holocene paleoclimate in Bosten Lake on the northern margin of the Tarim Basin, southern Xinjiang, is reconstructed through an analysis of a 953 cm long core (BSTC2000) taken from Bosten Lake. Multiple proxies of this core, including the mineral components of carbonate, carbonate content, stable isotopic compositions of carbonate, Ca/Sr, TOC and C/N and C/S of organic matter, are used to reconstruct the climatic change since 8500 a B.P. The chronology model is made by nine AMS 14C ages of leaves, seeds and organic matter contained in two parallel cores. The climate was cold and wet during 8500 to 8100 a B.P. Temperature increased from 8100 to 6400 a B.P., the climate was warm and humid, and the lake expanded. The lake level was highest during this stage. Then from 6400 to 5100 a B.P., the climate became cold and the lake level decreased slightly. During the late mid-Holocene, the climate was hot and dry from 5100 to 3100 a B.P., but there was a short cold period during 4400 to 3800 a B.P. At this temporal interval, a mass of ice and snow melting water supplied the lake at the early time and made the lake level rise. The second highest lake level stage occurred during 5200 to 3800 a B.P. The climate was cool and wet during 3100 to 2200 a B.P., when the lake expanded with decreasing evaporation. The lake had the last short-term high level during 3100 to 2800 a B.P. After this short high lake level period, the lake shrank because of the long-term lower temperature and reduced water supply. From 2200 to 1200 a B.P., the climate was hot and dry, and the lake shrank greatly. Although the temperature decreased somewhat from 1200 a B.P. to the present, the climate was warm and dry. The lake level began to rise a little again, but it did not reach the river bed altitude of the Konqi River, an outflow river of the Bosten Lake.ZHANG Chengjun ZHENG Mianping Alexander PROKOPENKO Steffen MISCHKE GOU Xiaohui YANG Qili ZHANG Wanyi FENG Zhaodong 2009Acta Geologica Sinica(English Edition)2009,83,6:10
