Abstract
A method of analyzing a rock sample includes analyzing one or more large-area, low-resolution micrographs to identify areas requiring higher-resolution imaging, and selecting one or more analysis regions from the areas requiring higher-resolution imaging. Multi-spectral imaging is used on the one or more analysis regions to obtain one or more high-resolution, multi-spectral images, and one or more features of the rock sample are identified from the corresponding one or more high-resolution, multi-spectral images. The method further includes upscaling the one or more high-resolution, multi-spectral images and thereby geo-locating the features of the rock sample to key regions of the rock sample.
