A total of 77 pottery shards originating from the Middle Jomon period (2500–1500 BC) were excavated from the Hinoki site in Tochigi, Japan. Fifty-nine of the shards were Atamadai-type pottery in which fragments containing biotite were mixed during the manufacturing process. For the provenance estimation of the biotite temper in the Atamadai-type pottery pieces, the reliance of the biotite's lattice spacing on the samples’ origin was verified using X-ray diffraction (XRD) measurements of seven biotite-containing rocks possessing the different provenances. Three samples showed significant differences in the lattice spacing of biotite 001. The remaining samples indicated no significant differences. In addition to lattice spacing, the clarification of the provenance dependency also requires the measurement of the solid-solution ratio (Mg/Fe).

用 XRD 对热玉台陶器（公元前 2500 年至公元前 1500 年）的起源估计揭示黑云母晶格间距的起源依赖性的初步研究

日本栃木县桧木遗址共出土了 77 块来自绳文中期（公元前 2500-1500 年）的陶器碎片。其中 59 个碎片是在制造过程中混合了含有黑云母的碎片的热玉代陶器。对于热玉台型陶器中黑云母回火的来源估计，使用具有不同来源的七种含黑云母岩石的 X 射线衍射 (XRD) 测量验证了黑云母晶格间距对样品来源的依赖性。三个样品显示黑云母001的晶格间距存在显着差异。其余样品没有显着差异。除了晶格间距之外，澄清来源依赖性还需要测量固溶比（Mg / Fe）。
