A wall-like mass of mineral matter, usually an intrusion of igneous rocks, filling up rents or fissures in the original strata.
Tabular igneous intrusion that cuts across planar bedding or foliation of the surrounding rock.
A small, discordant (injected into massive igneous, metamorphic, or across layers of sedimentary rock) body of intrusive igneous rock.
A dike is tabular, intrusive, igneous rock that cuts across the layering of adjacent rock, intrudes into an existing fracture, or creates a new fracture by forcing its way through pre-existing rock.
A sheet or wall-like mass of igneous rock that cuts across other rocks.
Dike - A tabular (book-shaped) igneous intrusion that cuts across the bedding of older rock.
a tabular (table-top-shaped) body of igneous rock that cuts across the struc-ture of the country rocks. It is a discordant igneous intrusion.
A dike is a long and narrow (tabular, like a table top) "discordant" magmatic intrusion; dikes cut across local sediment and rock layers. Back
A discordant pluton that is substantially wider than it is thick. Dikes are often steeply inclined or nearly vertical. See also sill. dilatancy The expansion of a rock's volume caused by stress and deformation.
Figure A dike is an intrusive igneous body that cuts across the grain of the rock it intrudes. Compare sill.
A tabular intrusive rock that cuts across strata or other structural features of the surrounding rock.
volcanic rock entering the bedrock perpendicular.
A tabular igneous intrusion that cuts across the host bedrock.
A long, narrow and more or less vertical mass of igneous or eruptive rock intruded into a fissure of surrounding older rock.
A near vertical, planar, volcanic intrusion.
A tabular intrusion of igneous magma that cuts across fractures or planar structures of the surrounding rocks.
a formation of igneous rock that can form exposed vertical or linear ridges
an igneous intrusion that cuts across the foliation of the host rock
an igneous rock that is intruded across layers of sediments
an intrusion into a cross-
a rock structure caused when solid rock cracks and molten rock from the magma below is forced up through the crack and then solidifies
a sheetlike body that fills a fracture that cuts across other rocks
a tabular body of igneous rock cutting across bedding and hence, discordant
a tabular or sheet-like discordant igneous rock body
a tabular (shaped like a wall) usually vertical to nearly vertical intrusive igneous body that cuts through existing rocks
a vertical or near vertical intrusive igneous rock igneous rock body that cuts across the rock beds
A tabular body of rock hardened from a molten state (igneous intrusion) that has cut across the bedding or alignment of the surrounding rock.
It is a term given to the wall of igneous rock which cuts across layers of surrounding rock.
A sheetlike body of igneous rock that cuts across layering or contacts in the rock into which it intrudes.
A sheet-like or tabular-shaped igneous intrusion that cuts across the sedimentary layering, metamorphic foliation, or other texture of a pre-existing rock. more details...
a tabular or sheetlike body of igneous rock that cuts across the structure of adjacent rocks into which it intrudes.
A tabular body of igneous or lava rock that cuts across adjacent rocks or cuts massive rock.
A tabular (wall-shaped) intrusion of rock that cuts across the layering of country rock.
A dike is a sheet-like intrusion of magma (molten rock) that froces its way through a layer of fractured rock. The magma flows through cracks in the rock and later cools and solidifies into a sheet of igneous rock.
a volcanic intrusive rock perpendicular to dominant stratigraphy.
A tabular body of igneous rock that cuts across the structure of adjacent rocks or cuts through massive rocks. Chasm View in the Black Canyon of the Gunnison, Colorado, exposes some good examples of dikes.
An igneous intrusion that cuts across the bedding of the country rock;
An embankment of earth and rock; especially, a levee built to hold water.
geologic structure deriving from fracture filled by foreign material and younger than country rocks.
A long, narrow body (like a table top on its side) that cuts into cooler rocks.
Rising magma cooling underground which cuts vertically across exisiting rock. Dikes and sills of Keweenawan time arose among the older Rove Formation which runs from Gunflint Lake east to Superior (our BWCA Region V). More resistant to erosion and glaciation than the surrounding rock, they delineate the long and narrow lakes which are the hallmark of this region.
a long mass of igneous rock that was intruded into a crosscutting fissure in older rock; a discordant intrusive body of tabular rock. [AHDOS
A tabular igneous intrusion that cuts across structures of surrounding rock. (See also Discordant intrusion.)
A dike or dyke in geology refers to an intrusive igneous body. The thickness is usually much smaller than the other two dimensions. Thickness can vary from sub-centimeter scale to many meters in thickness and the lateral dimensions can extend over many kilometers.
