| 1 | 贵州荔波黑洞碎屑沉积物宇宙成因核素^(26)Al/^(10)Be埋藏年龄显示文摘河流下切在岩溶区形成的多级层状洞穴,记录了地体隆升和地貌演化历史,但由于测年手段的限制,国内在这方面的研究一直进展不大。近年来,运用宇宙成因核素得到洞穴碎屑沉积物埋藏年龄的方法,已成为反演山地区域构造-地貌演化的新途径。本文尝试运用宇宙成因核素^(26)Al/^(10)Be埋藏测年技术,对属于贵州荔波地区4层洞穴系统的黑洞(第二层)碎屑沉积物进行年龄测定,假设样品进洞前无埋藏史,测年结果显示黑洞年龄至少有1.06±0.23Ma,并且该地区三岔河流域的侵蚀速率为55.1±2.3m/Ma。这是对该地区洞穴测年的一次新探索,体现出洞穴沉积物宇宙成因核素埋藏测年技术在我国晚新生代地质地貌演化研究方面具有良好的应用前景。 | 刘彧 王世杰 刘秀明 徐胜 Derek Fabel 罗维均 | 2013 | 第四纪研究2013,33,3: | 12 |
| 2 | Cosmic-ray exposure age of Martian meteorite GRV 99027显示文摘We have determined the concentrations of 10Be and 26Al in GRV 99027 recovered by the 16th Chinese Antarctic expedition team, which are 14.1 ± 0.6 dpm/kg and 67.5 ± 3.4 dpm/kg, respectively. From the concentration of 10Be, we calculate a cosmic-ray exposure age of 4.4 ± 0.6 Ma for GRV 99027. The concentration of 26Al is too high compared to the 10Be exposure age, indicating extra production from solar ray. The exposure ages, petrologic and geochemical characteristics of mantle-derived Martian meteorites GRV 99027, LEW 88516, Y-793605, NWA 1950 and ALHA77005 are very similar, suggesting that these meteorites most probably were ejected from Mars in the same impact event. | D.

| 18 | 贵州高原沉积物原位宇宙成因核素^(10)Be、^(26)Al和^(21)Ne测年研究显示文摘地貌演化受到区域构造抬升、气候变化和河流动力学共同调节.然而,如何通过地表剥蚀和河流下切作用来区分这些机制仍存在争议.本文对贵州高原地区洞穴沉积物、现代河流沉积物和基岩中石英颗粒的原位宇宙成因核素^(10)Be、^(26)Al和^(21)Ne含量进行分析,探讨了^(21)Ne在地质年代学中的适用性,并讨论了该地区第四纪地貌演化历史.通过^(26)Al-^(10)Be和^(21)Ne-^(10)Be核素对的对比分析,我们发现石英样品中由U和Th衰变产生的核反应成因^(21)Ne含量不可忽视,同时也有可能存在继承性宇宙成因^(21)Ne.在前人的研究基础上,我们总结了宇宙成因核素^(21)Ne精确定年须注意的几个方面:(1)评估样品中核反应成因^(21)Ne的贡献;(2)避免采集有复杂埋藏历史的样品以排除继承性^(21)Ne的影响;(3)对第四纪样品^(10)Be-^(26)Al-^(21)Ne三核素联用.基于^(26)Al-^(10)Be核素对计算出的样品埋藏年代和流域在埋藏前的剥蚀速率,我们确定了贵州高原地区不同时间尺度地表剥蚀速率和河流下切速率的变化.不同时间尺度的^(26)Al-^(10)Be流域剥蚀速率、^(36)Cl剥蚀速率和现代河流剥蚀速率的一致性,表明贵州高原景观尺度的地表剥蚀速率可能在第四纪以来已经达到稳定状态.该地区河流下切速率略高于局部地表剥蚀速率,表明区域构造抬升导致的河流动力学可能尚未达到稳定状态. | 杨业 刘彧 马严 徐胜 刘丛强 王世杰 Finlay M.STUART Derek FABEL | 2021 | 中国科学:地球科学2021,51,8: | 1 |
