What is petrology explain?
petrology, scientific study of rocks that deals with their composition, texture, and structure; their occurrence and distribution; and their origin in relation to physicochemical conditions and geologic processes. It is concerned with all three major types of rocks—igneous, metamorphic, and sedimentary.
What is the origin of petrology?
Petrology (from the Ancient Greek: πέτρος, romanized: pétros, lit. ‘rock’ and λόγος, lógos) is the branch of geology that studies rocks and the conditions under which they form.
What is the difference between geology and petrology?
Geology is the scientific study of the structure and composition of the earth whereas petrology is a branch of geology that is concerned with the structure, composition, and distribution of rocks. This is the key difference between geology and petrology.
Which is a metamorphic rock?
Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Foliated Metamorphic Rocks: Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned.
What is the study of rock?
Petrology is the study of rocks – igneous, metamorphic, and sedimentary – and the processes that form and transform them. Mineralogy is the study of the chemistry, crystal structure and physical properties of the mineral constituents of rocks.
Why is the study of rocks important?
Geologists study rocks because they contain clues about what the Earth was like in the past. Different rocks form under only certain conditions and even the dullest gray lump of a rock can tell us something important about the past. …
What science is the study of rocks?
What is the difference between lithology and petrology?
Lithology was once approximately synonymous with petrography, but in current usage, lithology focuses on macroscopic hand-sample or outcrop-scale description of rocks while petrography is the speciality that deals with microscopic details.
What rocks are made from lava?
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian, and volcanic ash and dust.
What is the study of rocks and fossils called?
Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.
What is the study of rocks and earth?
Introduction. The study of geology is the study of the Earth, and so is ultimately the study of rocks. Geologists define a rock as: A bound aggregate of minerals, mineraloids, or fragments of other rocks.
What is the meaning of petrology?
Petrology (from the Ancient Greek: πέτρος, romanized: pétros, lit. ‘rock’ and λόγος, lógos) is the branch of geology that studies rocks and the conditions under which they form.
What is the relationship between mineralogy and petrology?
Petrology is the study of rocks, and, because most rocks are composed of minerals, petrology is strongly dependent on mineralogy.
What is the difference between petrology and igneous rocks?
Igneous rocks are rocks formed by the crystallization of magma or molten rock. Petrology refers to the scientific study of rocks and the conditions which influence their formation. Petrology is a branch of geology that focuses on the chemical analysis in various fields such as petrography and mineralogy.
What is the scale of petrology?
Scale box is 0.25 mm. Petrology (from the Ancient Greek: πέτρος, romanized : pétros, lit. ‘rock’ and λόγος, lógos) 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
