摘要

Abstract >Provenance studies of widely distributed tephras, integrated within a well‐defined temporal framework, are important to deduce systematic changes in the source, scale, distribution, and changes in regional explosive volcanism. Here, we establish a robust tephrochronostratigraphy for a total of 157 marine tephra layers collected during IODP Expedition 352. We infer at least three major phases of highly explosive volcanism during Oligocene to Pleistocene time. Provenance analysis based on glass composition assigns 56 of the tephras to a Japan source, including correlations with 12 major and widespread tephra layers resulting from individual eruptions in Kyushu, Central Japan, and North Japan between 115 ka and 3.5 Ma. The remaining 101 tephras are assigned to four source regions along the Izu‐Bonin arc. One, exclusively assigned to the Oligocene age, is proximal to the Bonin Ridge islands; two reflect eruptions within the volcanic front and back‐arc of the central Izu‐Bonin arc, and a fourth region corresponds to the Northern Izu‐Bonin arc source. First‐order volume estimates imply eruptive magnitudes ranging from 6.3 to 7.6 for Japan‐related eruptions and between 5.5 and 6.5 for IBM eruptions. Our results suggest tephras between 30 and 22 Ma reflect a subtly different Izu‐Bonin chemical signature compared to the recent arc. After a ～9 Ma gap in eruption, tephra supply from the Izu‐Bonin arc predominated from 15 to 5 Ma, and finally a subequal mixture of tephra sources from the (palaeo)Honshu and Izu‐Bonin arcs occured within the last ～5 Ma. </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 Type =“main”> <标题类型=“main”>抽象</ title> >众所周地分布的Tephras的出处研究，集成在明确定义的时间框架内，对区域爆炸性火山主义的源，规模，分布和变化的系统变化进行了推移，这是重要的。在这里，我们在IODP探险期间共收集的157个海洋Tephra层的强大的Tephrochronatraphy。在寡核苷中，我们在寡核苷酸期间推断至少三个高爆炸的火山阶段。基于玻璃组成的出现分析将56分配给日本来源，包括与九州，日本中部和北日本之间的个人爆发引起的12个主要和广泛的Tephra层的相关性，115 ka和3.5 ma之间。剩下的101台Tephras沿着Izu-Bonin弧分配到四个源区。一个专门分配给寡核苷的年龄，是靠近博林岭岛的近端;两个反映中央Izu-Bonin弧的火山前后的爆发，第四个区域对应于北Izu-onin弧源。一阶卷估计暗示日本相关爆发的6.3至7.6的爆发幅度范围和5.5和6.5用于IBM爆发。我们的结果表明，与最近的弧相比，Tephras在30到22 mA之间反映了巧妙的不同Izu-bonin化学特征。在喷发〜9 mA的间隙后，从伊夸 - 波隆弧的Tephra供应占主导地位的15至5 mA，最后从（Palaeo）Honshu和Izu-Bonin弧中的Tephra来源的副等混合物在过去5 mA之内发生。</ 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-23285/'>《Geochemistry, geophysics, geosystems》</a> <b style="margin: 0 2px;">|</b><span>2018年第1期</span><b style="margin: 0 2px;">|</b><span>共25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=Kutterolf S.&option=202" target="_blank" rel="nofollow">Kutterolf S.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Schindlbeck J.
