Mineralogy As a discipline, mineralogy has had close historical ties with geology.
Methodology[ edit ] Petrology utilizes the fields of mineralogypetrographyoptical mineralogyand chemical analysis to describe the composition and texture of rocks.
Petrologists also include the principles of geochemistry and geophysics through the study of geochemical trends and Sedimentary petrology and the use of thermodynamic data and experiments in order to better understand the origins of rocks.
Branches[ edit ] There are three branches of petrology, corresponding to the three types of rocks: Igneous petrology focuses on the composition and texture of igneous rocks rocks such as granite or basalt which have crystallized from molten rock or magma.
Igneous rocks include volcanic and plutonic rocks. Sedimentary petrology focuses on the composition and texture of sedimentary rocks rocks such as sandstoneshaleor limestone which consist of pieces or particles derived from other rocks or biological or chemical deposits, and are usually bound together in a matrix of finer material.
Metamorphic petrology focuses on the composition and texture of metamorphic rocks rocks such as slatemarblegneissor schist which started out as sedimentary or igneous rocks but which have undergone chemical, mineralogical or textural changes due to extremes of pressure, temperature or both Experimental petrology employs high-pressure, high-temperature apparatus to investigate the geochemistry and phase relations of natural or synthetic materials at elevated pressures and temperatures.
Experiments are particularly useful for investigating rocks of the lower crust and upper mantle that rarely survive the journey to the surface in pristine condition.
They are also one of the prime sources of information about completely inaccessible rocks such as those in the Earth's lower mantle and in the mantles of the other terrestrial planets and the Moon.
The work of experimental petrologists has laid a foundation on which modern understanding of igneous and metamorphic processes has been built.The earlier editions of this book have been used by successivegenerations of students for more than 20 years, and it is thestandard text on the subject in most British universities and manyothers throughout the world/5.

Sedimentary petrology is the study of their occurrence, composition, texture, and other overall characteristics, while sedimentology emphasizes the processes by which sediments are transported and deposited.
Sedimentary petrography involves the classification and study of sedimentary rocks using the petrographic microscope.
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.
