IODP Expedition 369 Whole-round core section images

Images of the outside of hard rock whole-round sections were acquired using a linescan imager (Section Half Imaging Logger [SHIL]) and a special holder that allows each 90 degree segment of the outer surface to be positioned properly. The images were taken at a resolution of 20 lines/mm (50 micropixels). JRSO staff take these quadrant images and compile them into a side-by-side rollout photograph of the section. Composite images are available as both JPG and TIF image formats. Individual quadrant images are available as JPG images only through this report; contact the IODP-JRSO Data Librarian if quadrant TIF files (~160 MB) are needed.硬质完整圆柱岩心的外表面图像采用线扫描成像仪（linescan imager）与半岩心成像测井仪（Section Half Imaging Logger，缩写SHIL）及专用夹具采集，该夹具可确保岩心外表面的每一个90°扇形分段均能被精准定位。图像采集分辨率为20线/毫米（50微像素）。JRSO工作人员将这些象限图像拼接为该岩心段的并排式展开全景照片。拼接后的复合图像可提供JPG与TIF两种格式版本。单个象限图像仅可通过本报告获取JPG格式版本；若需象限图像的TIF格式文件（单文件大小约160 MB），请联系IODP-JRSO数据馆员。
