Constraints on the composition and temperature of LLSVPs from seismic properties of lower mantle minerals

This file contains the 79 394 successful models investigated for LLSVPs. For each model, we provide 23 properties describing the composition and its main characteristics. These properties are as follows: - The six input parameters of our model (plus the proportion of Fp). R_Fe is the oxidation state, while DT is the temperature contrast between LLSVPs and far-field mantle. - The bulk composition of the rock in term of its 5 main oxides. - The chemical composition of Fp and Bm in term of their sub-phases. - The four outputs used in this study, namely the bulk rock density, the P-wave velocity (Vp), the S-wave velocity (Vs), and the bulk sound velocity (Vphi). All the details concerning the calculation are available in the corresponding article.本数据集包含针对大型低剪切波速度省（Large Low Shear Velocity Provinces，LLSVPs）开展研究得到的79394个成功模型。针对每个模型，我们提供了23项属性，用于描述其组分与核心特征。具体属性如下： - 本模型的六项输入参数（外加Fp占比）。其中R_Fe代表氧化状态，DT则为LLSVPs与远场地幔间的温度差。 - 以5种主要氧化物形式表征的岩石整体组分。 - 以子相形式呈现的Fp与Bm的化学组分。 - 本研究使用的四项输出参数，分别为岩石整体密度、纵波速度（Vp）、横波速度（Vs）以及体积声速（Vphi）。 有关本次计算的全部细节均可参阅对应研究论文。
