摘要

Abstract > We analyzed helium and neon in 24 samples from between 3,607 and 3,767?m (i.e., down to 2?m above the lake‐ice interface) of the accreted ice frozen to the ceiling of Lake Vostok. Within uncertainties, the neon budget of the lake is balanced, the neon supplied to the lake by the melting of glacier ice being compensated by the neon exported by lake ice. The helium concentration in the lake is about 12 times more than in the glacier ice, with a measured 3 He/ 4 He ratio of 0.12?±?0.01?R <sub>a</sub> . This shows that Lake Vostok's waters are enriched by a terrigenic helium source. The 3 He/ 4 He isotope ratio of this helium source was determined. Its radiogenic value (0.057?×?R <sub>a</sub> ) is typical of an old continental province, ruling out any magmatic activity associated with the tectonic structure of the lake. It corresponds to a low geothermal heat flow estimated at 51?mW/m 2 . </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”XML：Lang =“en”> <标题类型=“main”>抽象</ title> >我们在24个样本中分析了氦气和霓虹灯，在3,607和3,767？m（即，向下在沃斯托克湖天花板上冰冻冰湖上方的2？m。在不确定因素中，湖泊的霓虹灯预算平衡，通过冰川冰融化的霓虹灯供应到湖泊的霓虹灯被湖冰湖出口的霓虹灯弥补。在湖中的氦浓度大于在冰川约12次，用测得的<SUP> 3 </ SUP>他/ <SUP> 4 </ SUP> 0.12赫比α±？0.01·R <子> a </ sub>。这表明沃斯托克湖的水域富裕地富裕。确定该氦源的 3 </ sup> He / 4 </ sup> He同位素比例。其辐射性值（0.057？××r <sub> a </ sub>）是旧的大陆省的典型，统治了与湖泊构造结构相关的任何岩石活动。它对应于在51Ωmw/ m 2 </ sup>的低地热流量。 </ p> </ abstract> </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-23539/'>《Geophysical Research Letters》</a> <b style="margin: 0 2px;">|</b><span>2018年第10期</span><b style="margin: 0 2px;">|</b><span>共6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=Jean‐Baptiste P.&option=202" target="_blank" rel="nofollow">Jean‐Baptiste P.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Fourré E.&option=202" target="_blank" rel="nofollow">Fourré E.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Petit J.
