本数据文章中介绍的三维岩性分布模型与Takeuchi等人的“Stochastic modeling of 3-D composite distribution in the crust with Bayesian inference and application to geoneutrino observation in Japan”相关。（2019）[1]。我们的目标区域是日本主要岛屿及其附近的地壳和上地幔。我们将目标区域离散为79,968个网格点。我们定义了31种岩石类型; 29种主要的地壳岩石类型，加上沉积物和地幔。我们的岩性模型表示从地震层析成像模型推断的概率分布图，并允许定量研究与误差估计，使其从根本上不同于以前的模型。为了实现这样的定量应用，我们提供了明确的数值数据的31种岩石类型的概率为每个网格点。我们还提供了明确的值的体积比例岩性模型在不同的深度和散装整个地壳。此外，还给出了一幅合成重力数据图，以纠正有关文献[1]中的一个微小误差。
The 3D lithological distribution model presented in this data article is related to “Stochastic modeling of 3-D compositional distribution in the crust with Bayesian inference and application to geoneutrino observation in Japan” by Takeuchi et al. (2019) [1]. Our target region is set to the crust and uppermost mantle beneath Japanese main islands and their vicinity. We discretized the target region into 79,968 grid points. We defined 31 rock types; 29 major crustal rock types, plus sediment and mantle. Our lithology model represents a probabilistic distribution map inferred from a seismic tomography model and allows quantitative studies with error estimations, making it fundamentally different from previous models. To enable such quantitative applications, we provide explicit numerical data for the probabilities of the 31 rock types for each grid point. We also provide explicit values of the bulk proportion lithology model at various depths and for the bulk whole crust. Further, a figure of synthetic gravity data is presented to correct a minor error in the related paper [1].
