Which one is an intrusive igneous rock body that is tabular and concordant?

Which one is an intrusive igneous rock body that is tabular and concordant?

A sill is a tabular body which is concordant. A blister shaped sill is called a laccolith. A pegmatite is a extremely coarse-grained igneous rock with crystals as large as 10 meters across.

Is batholith tabular or massive?

Large, irregularly shaped plutons are called stocks or batholiths, depending on size. Tabular plutons are called dikes if they cut across existing structures, and sills if they do not.

What are the concordant and discordant forms of igneous rocks?

These are concordant bodies of igneous rocks that occurs along the crests and troughs of the folded sedimentary strata….

What is a tabular concordant pluton?

A tabular or sheetlike concordant pluton. stock. An irregularly shaped discordant pluton with a surface area smaller than 100 km2. stoping. A process in which rising magma detaches and engulfs pieces of the country rock.

Is batholith concordant or discordant?

Batholiths. Batholiths are discordant intrusions with an exposed area greater than 100 square kilometers (39 sq mi).

What’s the definition of a batholith?

Definition: Despite sounding like something out of Harry Potter, a batholith is a type of igneous rock that forms when magma rises into the earth's crust, but does not erupt onto the surface.

Is a concordant body?

An intrusive igneous body whose contacts are parallel to the bedding of the country rock. Also known as concordant injection; concordant pluton.

What is concordant igneous rocks?

Laccoliths: Laccoliths are concordant igneous bodies with their lower surface flat and upper surface arched in the form of dome (Fig. 8) such bodies are naturally formed due to the accumulation of viscous magma underneath the rocks occurring upon the surface. Laccoliths may have dykes or sill acting as their feeders.

What is concordant igneous intrusion?

Concordant intrusions A sill is a tabular concordant intrusion, typically taking the form of a sheet parallel to sedimentary beds. They are otherwise similar to dikes. Most are of mafic composition, relatively low in silica, which gives them the low viscosity necessary to penetrate between sedimentary beds.

Are types of concordant igneous rock bodies?

PHACOLITHS: These are concordant bodies that occurs along the crests and troughs of the folded sedimentary strata. CHONOLITHS: This term is applied to all other intrusive igneous bodies with irregular shape, i.e. the body with no specific shape.

What are concordant bodies?

Concordant bodies are those organizations that are affiliated with Freemasonry. Many concordant bodies require membership in a Blue Lodge prior to joining. The Scottish Rite is a concordant body of Masonry, meaning that it is not part of the Craft Lodge per se, but closely associated with Masonry.

What is an igneous batholith?

Definition: Despite sounding like something out of Harry Potter, a batholith is a type of igneous rock that forms when magma rises into the earth's crust, but does not erupt onto the surface.

Which intrusive features are concordant?

Lopoliths are concordant intrusions with a saucer shape, somewhat resembling an inverted laccolith, but they can be much larger and form by different processes.

Which of the following is concordant igneous body?

Laccoliths: Laccoliths are concordant igneous bodies with their lower surface flat and upper surface arched in the form of dome (Fig. 8) such bodies are naturally formed due to the accumulation of viscous magma underneath the rocks occurring upon the surface. Laccoliths may have dykes or sill acting as their feeders.

What is batholith and laccolith?

The batholith is a large irregular mass of intrusive igneous rocks that forces themselves in surrounding strata, and laccolith is a mass of igneous or volcanic rock within strata. Batholith and laccoliths are part of igneous rocks and volcanic landforms.

Are Laccoliths concordant?

Both laccoliths and sills are classified as concordant intrusions, since the bulk of the intrusion does not cut across host rock strata, but intrudes between strata.
