(Table 1) Lead isotopic composition and concentration at DSDP Leg 82 Holes

The aim of DSDP Leg 82 was to decipher the temporal and spatial evolution of Azores Plume. The Pb-isotopic results of this leg are rather complex, and can be summarized as follows:
1. At a given site (561, 558), variations of Pb isotopic compositions are generally accompanied by major changes in trace-element ratios, indicating significant heterogeneity of the source region. There is a correlation between Pb isotopes and trace elements. […]

深海钻探计划（Deep Sea Drilling Project, DSDP）第82航次的核心目标，是解析亚速尔地幔柱（Azores Plume）的时空演化规律。本次航次获得的铅同位素（Pb-isotopic）测试结果较为复杂，可归纳如下：
1. 在指定站位（561、558）中，铅同位素组成的变化通常伴随微量元素比值的显著改变，表明源区存在显著的非均质性；铅同位素与微量元素之间存在相关性。[……]
