收藏资源简介：
<strong>Contents of the dataset:</strong> 1. Downhole_mineral_BT1B_loadA_all03292020.m: a MATLAB script calculating the mineral fraction from XCT images. Results were saved in “Result_mineral_03292020.mat”. 2. Downhole_countPorosity_BT1B_loadA_all_06072020.m: a MATLAB script calculating porosity. Results were saved in “Result_porosity_06082020_2.mat”. 3. Downhole_countHeavyM_BT1B_loadA_all_06072020.m: a MATLAB script calculating the volume fraction of heavy minerals. Results were saved in “Result_heavy_mineral_06082020.mat”. 4. 805C5704B<strong>xxx</strong>Z<strong>yy</strong>: folders containing analytical results from XCT images from Core <strong>xxx</strong> Section <strong>yy</strong> from the Hole BT1B as listed below. 4-1. Result_CTmeanmode_04072020.mat: results of mean and mode of CT numbers of each XCT X-Y slice from Core <strong>xxx</strong> Section <strong>yy</strong>. 4-2. Result_mineral_03292020.mat: contains QMD (quartz-magnetite-dolomite fraction in volume fraction), abc123 (fitting results of <em>a<sub>i</sub></em>, <em>b<sub>i</sub></em> and <em>c<sub>i</sub></em> in Eq. 4 in the manuscript), abc95 (95% confidential intervals of <em>a<sub>i</sub></em>, <em>b<sub>i</sub></em> and <em>c<sub>i</sub></em>.), and R2 (<em>R<sup>2</sup></em>-value of fitting results). 4-3. Result_porosity_06082020_2.mat: fitting result of porosity from Core <strong>xxx</strong> Section <strong>yy</strong>. 4.4. Result_heavy_mineral_06082020.mat: fitting result of the volume fraction of heavy minerals from Core <strong>xxx</strong>Section <strong>yy</strong>. 5. downholemineral_R<strong>ZZ</strong>_03292020.mat: average of mineral fraction of each core section. <strong>ZZ</strong> indicates the applied threshold <em>R<sup>2</sup></em>-value. This file contains following variables; <em>sec</em>: section number of the core sample, <em>core</em>: core number of the core sample, <em>depth</em>: downhole depth at the top of the core sample, <em>Quartz</em>: average volume fraction of quartz in the core sample, <em>Magnesit</em>e: average volume fraction of maginesite in the core sample, <em>Dolomite</em>: average volume fraction of dolomite in the core sample, <em>molSiO2</em>: average mole fraction of SiO<sub>2</sub> in the core sample, <em>molMgO</em>: average mole fraction of MgO<sub>2</sub> in the core sample, <em>molCaO</em>: average mole fraction of CaO in the core sample, 6. downhole_CT_porosity_06082020.mat: average of porosity of each core section with threshold <em>R<sup>2</sup></em>-value of 0.99. 7. downhole_heavymineral06082020.mat: : average of the heavy mineral fraction of each core section with threshold <em>R<sup>2</sup></em>-value of 0.99.
