15 fractures of granite

Description

The surface topographies of natural rock fractures of 9 Aji granites (fine grain size) and 6 Inada granites (medium grain size) containing a single tensile fracture, obtained using a 3D microscope. The data set was used for synthetic fracture generation and further analysis for a series of Lattice Boltzmann fluid flow simulations and finite element analysis of electrical and elastic properties to relate hydraulic-electrical-elastic properties of fractures. File opening: Any of the files in this project can be opened in MATLAB simply using 'load' command, but also also in open source Python environments using 'hdf5storage' package (please install it as necessary). Here is an example script for a file named 'hangwall.mat' and assuming you have downloaded this file into the same directory where you are running the script: from hdf5storage import loadmat import matplotlib.pyplot as plt # 'H' is the dictionary key for "hangwall.mat" # For footwall*, the dictionary key appears to be 'F' img = loadmat(r'hangwall.mat')['H'] plt.figure() plt.imshow(img)
