Petrology and cycles and the use of thermodynamic data and experiments in order to better understand the origins of rocks. There are three branches of petrology, corresponding to the three types of rocks: igneous, metamorphic, and sedimentary, and another dealing with experimental techniques: Petrology Petrology (from the Greek πέτρος, "pétros", "rock" and λόγος, "lógos", "subject matter", see -logy) is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together because they both contain heavy use of chemistry, chemical methods, and
Empirical study of literature raised to the empirical study of literature are the triviality of many of its research results such as confirmation of what was already known or suspected or its reductionism (artificiality of the framework and set-up, and limitation to reader response instead of the study of the text). It is clear, however, that the empirical study of literature by its specific approach of the object and its focus on methodology is an outstanding way to explore the socio-cultural aspects of the literary system. It makes an irreplaceable contribution to the development of a more rational, scientific, and socially relevant study of
