CSRM-derived: A 3-D crustal composition model in continental China

<p>This dataset contains a three-dimensional crustal composition model of the SiO2 content in the crustal bedrocks beneath continental China, derived from the <strong>CSRM-1.0 </strong>(<strong><a href="https://doi.org/10.5281/zenodo.11098135">model link</a></strong>)<strong>. </strong>The spatial resolution of the composition model is <strong>~60</strong> km in the north-south seismic belt and trans-North China Orogen, and <strong>~120</strong> km in the rest of the continental China.<strong>&nbsp;</strong>This composition model results from a project of constructing the high-resolution China Seismological Reference Model (<strong>CSRM-1.0</strong>) in the top 100 km of the crust and uppermost mantle in continental China (<a href="https://doi.org/10.1029/2024JB029520">Xiao et al, JGR, 2024</a>).</p> <p>本数据库包含了利用 CSRM-1.0(<a href="https://doi.org/10.5281/zenodo.11098135">模型链接</a>)估算的中国大陆区域地壳内不同深度岩石内二氧化硅含量的模型。该模型在南北地震带和华北造山带的分辨率约为 <strong>60</strong> km,在中国大陆的其他区域约为 <strong>120</strong> km。该成分模型源于构建中国大陆区域高精度地壳和上地幔顶部 100 公里三维地震学模型 (<strong>CSRM-1.0</strong>) 的工作 (<a href="https://doi.org/10.1029/2024JB029520">Xiao et al, JGR, 2024</a>) 。</p>
