摘要

ABSTRACT > A tephra layer with normal grading in the sub‐bottom depth interval 119–122?cm in marine core SO202‐27‐6 was collected on Patton Seamount in the northeast North Pacific Ocean. Based on the geochemistry of volcanic glass shards determined by a wavelength dispersive electron probe micro‐analyser and an X‐ray fluorescence analyser, this layer is correlated to the Dawson tephra, a widespread late Pleistocene time marker tephra in Alaska and the Yukon. The age of the Dawson tephra in the core is 29.03?±?0.178 ka (1 sigma) based on a published age model. The Dawson tephra is revealed to have been deposited in the transition from marine isotope stage 3 to 2, i.e. the last stage of Heinrich Stadial 3 derived from the ice‐rafted debris signal. According to the correlation between Greenland (NGRIP ice core) and this core, the Dawson tephra occupies the record immediately before inter stadial 4 in the δ 18 O stratigraphy of NGRIP. The Dawson tephra on Patton Seamount includes lithic fragments, which suggests that it was deposited not only by fall‐out but also in part via another mechanism, such as icebergs from the Cordilleran ice sheet or seasonal sea ice. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XML：lang =“en”type =“main”> <标题类型=“main”>抽象</ title> > 在北部太平洋东北北部海洋的Patton Seamount上收集了亚底深度间隔119-122厘米的正常分级的Tephra层。基于由波长色散电子探针微分析仪和X射线荧光分析仪确定的火山玻璃碎片的地球化学，该层与Dawson Tephra相关，阿拉斯加和育空中的普遍晚期百良生物时期标记Tephra相关。基于公布的年龄模型的核心中Dawson Tephra的年龄是29.03？±0.178 ka（1 sigma）。 Dawson Tephars被揭示在海洋同位素第3至2阶段的过渡中沉积在过渡中，即Heinrich Stadial 3衍生自冰圆形碎片信号的最后阶段。根据格陵兰（NGRIP冰芯）与这座核心之间的相关性，道森Tephars在δ中的间隔4之前立即占据记录 18 </ sup> o ngrip的地层。 Patton Seamount上的道森Tephra包括岩石碎片，这表明它不仅通过掉落而且部分通过另一种机制沉积，例如来自Cordillan冰盖或季节性海冰的冰山。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-35770/'>《Journal of quaternary science: JQS》</a> <b style="margin: 0 2px;">|</b><span>2020年第2期</span><b style="margin: 0 2px;">|</b><span>共9页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Aoki Kaori&option=202" target="_blank" rel="nofollow">Aoki Kaori;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Tokyo Metropolitan University Hachioji CityTokyo Japan;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/27341.html" title="第四纪（系）">第四纪（系）;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Dawson tephra&option=203" rel="nofollow">Dawson tephra;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Heinrich Stadial&option=203" rel="nofollow">Heinrich Stadial;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=late Pleistocene&option=203" rel="nofollow">late Pleistocene;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=marine sediment&option=203" rel="nofollow">marine sediment;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=MIS3/2&option=203" rel="nofollow">MIS3/2;</a> </p> <div class="translation"> 机译：道森Tephra;Heinrich Stadial;晚熟;海洋沉积物;MIS3 / 2;
