   Petrology
   `Petrology` is a field of geology that focuses on the study of rocks and the conditions on which they form. The word `lithology` once was approximately synonymous with petrography, but today lithology is essentially a subdivision of petrology focusing on macroscopic hand-sample or outcrop-scale description of rocks. There are three branches of petrology, corresponding to the three types of rocks: igneous, metamorphic, and sedimentary.
