This data release contains photographs and photomicrographs from drill cores and cuttings of pre-Middle Jurassic basement rocks that are buried beneath Coastal Plain sedimentary deposits in Florida. These samples provide rare insights into deeply buried rocks that have no surface exposures and no known exposed correlates. These images were acquired to support the characterization, discrimination, and correlation of map units comprising Florida’s basement infrastructure (Deasy and others, 2024a). These are the original images. Annotated images with additional comments are available in the companion Data Report (Deasy and others, 2024b). Semi-quantitative mineral modes of many basement rocks are presented in a companion data release (Deasy and others, 2024c); geochemical analyses of many of the same samples are available in a third companion data release (Deasy and others, 2024d). Types of images included are hand sample photographs; optical photomicrographs in plane-, cross-polarized, and reflected light (PPL, XPL, and RL, respectively); and scanning electron microscope (SEM) images including back-scattered electron (BSE) images, cathodoluminescence (CL) images, and qualitative elemental abundance maps determined by energy dispersive spectroscopy (EDS). All images are in tag image file (.tif) format. Contents of this release are: 1) a table of image information (image_table.csv), 2) a zipped folder containing two hundred twenty (220) .tif images (images.zip), 3) a data dictionary (.csv) defining attributes (column headings) in image_table.csv, 4) and metadata (.xml).
