Geoscience Ontology, Geologic Features

Cavity filled with secondary minerals, denotes that cavities are filled vesicles, thus restricted to volcanic rock. Have to model as a cavity/with material. Rock hosts cavity

Lithosome in lithostratigraphic unit that occurs as individual beds interleaved with other constituents on the outcrop (m) scale or larger.

A sub-map scale sequence of strata, e.g. bouma sequence, fining-upward sequence, interbedded sandstone and mudstone... Repeated multiple times in a stratigraphic unit.

A stratigraphic section that contains a designated point in a stratigraphic sequence of essentially continuous deposition, preferably marine, chosen for its correlation potential. http://www.stratigraphy.org/upload/bak/chron.htm

Lithosome characterized by an internal sequence of units, which is repeated in a stacked sequence, e.g. fining-upward sequence, thickening upward sequence, bouma sequence.

Drill hole.

Primary or penecontemporaneous gap or cavity in the framework of a sedimentary rock, larger than grain-supported intersticies. May be open space or have partial to complete fill with secondary cement or introduced sediment.

Lithosome in a mixed/heterogeneous lithodemic unit that occurs in irregular bodies within unit

Lithosome in igneous or metamorphic geologic unit that occurs as layers alternating with other constituents.

Lithosome occurs as discrete lense-shaped bodies, not connected with other bodies.

Bubble-like cavity with concentric shells of finely crystalline minerals, open space remains in core of structure. Radiating fibrous structure may be present in secondary mineral fill. Typically in silicic volcanic rock.

A kind of rock body that has multiple occurrences in a single geologic unit. A mass of rock of uniform character, characterized by geometry, composition, and internal structure. (http://inspire.ec.europa.eu/codelist/CompositionPartRoleValue/lithosome)

An irregular cavity in a phaneritic igneous rock into which small crystals of the rock-forming minerals protrude.

A boundary between a rock body and the Earth's atmosphere or a water body.

Open space between particles in a granular aggregate.

Constraint: rock body must be a stratigraphic unit for which 'top' and 'bottom' are meaningful.

A rock object that represents a continuous strip of rock material that includes (has parts) a sequence of stratified layers.

Constraint: rock body must be a stratigraphic unit for which 'top' and 'bottom' are meaningful.

A rock object that represents a continuous strip of rock material that includes (samples) a sequence of stratified layers.

a specific interval or point in a specific sequence of rock stata that constitues the reference standard defining a stratigrphic unit or boundary

Lithosome occurs as intrusive, sheet-like bodies within the unit as an essential part of the unit.

Cavity in volcanic rock formed by trapped gas. Use amygdule if filled with secondary mineral.

Irregular cavity in rock, generic term with no connotation of origin of cavity. May be lined with crystals of different mineral compostion to the host rock
