Graviquake (Geology terminology ⛰️)
A graviquake is an earthquake occurring in an extensional tectonic setting, where the gravitational energy stored during the interseismic period is delivered by the collapse of a brittle upper crustal volume, slipping along a normal fault and generating the double couple recorded in the moment tensor solution. == References...

Leaverite (Geology terminology ⛰️)
Leaverite is a slang term used by geologists, mineralogists, archaeologists, and amateur rock collectors to identify a specimen in the field that may look interesting or valuable but not worth removing. Rocks identified as such are generally left where they were found, as there is not sufficient reason to attempt to remove them. The term leaverite derives from...

Joint (geology) (Geology terminology ⛰️)
In geology, and more specifically in structural geology, a joint is a break of natural origin in a layer or body of rock that lacks visible or measurable movement parallel to the surface of the fracture. Although joints can occur singly, they most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly spaced joints...

Chronostratigraphy (Geology terminology ⛰️)
Chronostratigraphy is the branch of stratigraphy that studies the ages of rock strata in relation to time. The ultimate aim of chronostratigraphy is to arrange the sequence of deposition and the time of deposition of all rocks within a geological region, and eventually, the entire geologic record of the Earth. The stand...

Subbasin (Geology terminology ⛰️)
A subbasin or sub-basin is a structural geologic feature where a larger basin is divided into a series of smaller basins with intervening intrabasinal highs. The term subbasin has common use in geologic literature, but has yet to be included in the API Glossary of Geology. == References...

Vug (Geology terminology ⛰️)
A vug, vugh, or vugg is a small- to medium-sized cavity inside rock. It may be formed through a variety of processes. Most commonly, cracks and fissures opened by tectonic activity are partially filled by quartz, calcite, and other secondary minerals. Open spaces within breccias formed by an ancient collapse are another important source of vugs. Vugs may also form when...

Stratigraphic unit (Geology terminology ⛰️)
A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features that characterize it. Units must be mappable and distinct from one another, but the contact need not be particula...

Sector collapse (Geology terminology ⛰️)
A sector collapse or lateral collapse is the structural failure and subsequent collapse of a minimum volume of 1 km3 of a volcano. Unlike smaller flank collapses, a sector collapse can involve the central volcanic pipe and historically this term had been restricted by some writers to such events in arc stratovolcanoes, but is now used for la...

Geological event (Geology terminology ⛰️)
A geological event is a temporary and spatially heterogeneous and dynamic happening in Earth history that contributes to the transformation of Earth system and the formation of geological strata. Event stratigraphy was first proposed as a system for the recognition, study and correlation of the effects of important physical or biological events on the broader strati...

Landmass (Geology terminology ⛰️)
A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. In the field of geology, a landmass is a defined section of continental crust extending above sea level. Continents are often ...

Friability (Geology terminology ⛰️)
In materials science, friability, the condition of being friable, describes the tendency of a solid substance to break into smaller pieces under stress or contact, especially by rubbing. The opposite of friable is indurate. Substances that are designated hazardous, such as asbestos or crystalline silica, are often said to be friable if small particles are ea...

Geon (geology) (Geology terminology ⛰️)
The term geon refers to large, geologic units of time. Geologists traditionally subdivide Earth history into a hierarchy of named intervals: eons, eras, periods, etc.. Historians subdivide the history of human activity into intervals that are comparatively much shorter. In both geological and historical scales, the divisions of equal rank are characteristically of unequal duration...

Primary rock (Geology terminology ⛰️)
Primary rock is an early term in geology that refers to crystalline rock formed first in geologic time, containing no organic remains, such as granite, gneiss and schist as well as igneous and magmatic formations from all ages. Webster's Revised Unabridged Dictionary published in 1913 provides the following term as used in geology: Primary rocks a term early used for rocks supp...

Depocenter (Geology terminology ⛰️)
A depocenter or depocentre in geology is the part of a sedimentary basin where a particular rock unit has its maximum thickness. Depending on the controls on subsidence and the sedimentary environment, the location of a basin's depocenter may vary with time, such as in active rift basins as extensional faults grow, link or become abandoned. == References...
