Dataset for "In Situ Observation of Pressure-Enhanced Hydrous–Anhydrous Solid Solution in Lower-Mantle SiO₂–AlOOH Phases"

This dataset supports the manuscript “In Situ Observation of Pressure-Enhanced SiO₂–AlOOH Solid Solution in the Lower Mantle” submitted to Geophysical Research Letters. The Excel workbook includes four worksheets:Table_S1: Experimental conditions and run products.Table_S2: Chemical compositions and lattice parameters of recovered run products.Table_S3: Experimental pressure-temperature conditions and cell parameters.Table_S4: DFT-derived cell parameters. These data support the reported phase relations, recovered-sample compositions, lattice parameters, and structural parameters in the SiO₂–AlOOH system.本数据集用于支撑投稿至《Geophysical Research Letters》（地球物理研究快报）的研究稿件《下地幔中压力增强型SiO₂-AlOOH固溶体的原位观测》。 该Excel工作簿包含四张工作表，分别为：Table_S1：实验条件与实验产物；Table_S2：回收实验产物的化学成分与晶格参数；Table_S3：实验压力-温度条件与晶胞参数；Table_S4：基于密度泛函理论（DFT, Density Functional Theory）推导得到的晶胞参数。 上述数据可支撑SiO₂-AlOOH体系中已报道的相平衡关系、回收样品化学成分、晶格参数及结构参数相关研究结论。
