geology terms that start with f

But that does not mean there are rocks available for study for all of these time units. Synonyms for geology include geography, chorography, geomorphology, cartography, physiography, topology and earth science. List Edit. There are numerous topics in the field of geology, some of which include oceanography, geoarchaeology, geophysics, volcanology, paleontology, and plate tectonics, just to name a few. Aa flows commonly develop from pahoehoe flows as they cool and lose gas. Sorted by name; initial letter means Igneous, Sedimentary or Metamorphic rocks.. A Edit I Andesite – an intermediate volcanic rock M Anthracite – a form of hard coal B Edit S Banded iron formation – a fine grained chemical sedimentary rock composed of iron oxide minerals S Bauxite – the main ore of aluminium.It is mostly aluminium oxide. Antonym of syncline. The term implies extrememly long duration or remoteness in the past, although no precise limits can be set. Geologic Time Scale with ages shown in … A Aa: Hawaiian term used to describe a lava flow whose surface is broken into rough angular fragments. Acre-foot: The volume of water required to cover one acre of land to a depth of one (1) foot. note: The following is taken from several on-line sources, chiefly Illustrated Glossary of Geologic Terms by Steven M. Richardson, professor of geology at Iowa State University (based on the glossary in Earth: An Introduction to Geologic Change, by S. Judson and S.M. Definitions of terminology used in geology. Find more similar words at wordhippo.com! anticline - A fold of rock layers with a convex shape pointing upwards. aphanitic - An igneous rock in which the matrix grains are too small to be seen with the unaided eye. List of Minerals, Large mineral database and mineralogy reference, GeologyPage Absolute Date: An estimate of the true age of a mineral or rock based on the rate of decay of radioactive minerals. 3. n. [Formation Evaluation] A general term for the rock around the borehole.In the context of formation evaluation, the term refers to the volume of rock seen by a measurement made in the borehole, as in a log or a well test.These measurements indicate the physical properties of this volume. Extrapolation of the properties beyond the measurement volume requires a geological model. Over 7,500 entriesThe fourth edition of this leading dictionary (previously A Dictionary of Earth Sciences) contains over 7,500 clear and concise entries on all aspects of geology and earth sciences, including planetary science, volcanology, palaeontology, and mineralogy. Geologic history of Earth, evolution of the continents, oceans, atmosphere, and biosphere.The layers of rock at Earth’s surface contain evidence of the evolutionary processes undergone by these components of the terrestrial environment during the times at which each layer was formed. Opposite of phaneritic. The time extending from the end of the formative period of the earth to the beginning of human history; the part of the earth's history that is recorded in the succession of rocks. geologic time. The figure of the geologic time scale, represents time flowing continuously from the beginning of the Earth, with the time units presented in an unbroken sequence.
