Calcium Isotope Fractionation in Plagioclase from Mafic-Ultramafic Rocks: Implications for Magmatic Processes and Planetary Differentiation

Here are a total of 10 tables. Table 1 shows the whole-rock major element compositions of the Panzhihua and Xiaohaizi intrusions; Table 2 presents the calcium isotope compositions of the whole-rock, clinopyroxene, and plagioclase in the two intrusions; Table 3 lists the Δ44/40CaPl-cpx values of samples in the two intrusions; Table 4 is the estimated Plagioclase-Melt Ca Fractionation Factors at 1273K; Table 5 is the estimated calcium isotopic composition of residual melts during the solidification of the lunar magma ocean;Table S1 shows the trace element data of clinopyroxene and plagioclase in the two intrusions; and Tables S2 to S5 respectively present the major element compositions of clinopyroxene and plagioclase in the Panzhihua and Xiaohaizi intrusions.

本次数据集共包含10张表格。表1收录了攀枝花与小海子岩体的全岩主量元素组成；表2展示了两个岩体中全岩、单斜辉石（clinopyroxene）及斜长石（plagioclase）的钙同位素组成；表3列出了两个岩体中各样品的Δ⁴⁴/⁴⁰CaPl-cpx值；表4为1273K温度下估算得到的斜长石-熔体钙分馏因子（Plagioclase-Melt Ca Fractionation Factors）；表5为月球岩浆洋（lunar magma ocean）固结过程中残余熔体的估算钙同位素组成；表S1展示了两个岩体中单斜辉石与斜长石的微量元素数据；表S2至S5则分别展示了攀枝花与小海子岩体中单斜辉石及斜长石的主量元素组成。
