Rock classification from petrographic thin section analysis often requires expertise in mineralogy. This study developed a deep learning approach based on a convolutional neural network (CNN) to classify six igneous rock types from their thin section images. Petrographic image dataset with various image ...

Based on core observation, thin section examination and chemical analysis, igneous rocks in Block Zao 35, Zaoyuan oilfield, are divided into different lithologic types, and the log responses of these types are investigated. By analyzing correlation between lithologic types and their responses, a ...
A refined technique for measuring crystal size distributions in thin section Log-normal size distributions are of the form n=n o e L/α , where n=number density, L=crystal length, and α is a constant. A method for measuring three-d... TD Peterson - 《Contributions to Mineralogy & Petr...
Large igneous provinces(LIPs) are massive crustal emplacements of predominantly iron- and magnesium-rich (mafic) rock that form by processes other than normalseafloor spreading; they are the dominant form of near-surfacemagmatismon theterrestrial planetsand moons of our solar system.
