Dolerite rocks are a type of igneous rocks (formed as a result of cooling of magma or lava). They are mafic (45-52% SiO2), and subvolcanic (formed within the earth's crust). Within this characterisation there is considerable variation. Please see the link.
Dolerite is an Igneous rock formed below the Earth's surface, it is a form of basalt containing relatively little silica

Dolerite is an igneous rock :)
The four I know of are: gabbro, basalt, peridotite, and dolerite.
Dolerite is coarse grained variety of basalt, if present in the dorm of a dyke (discordent igneous body), it is called a dolerite dyke.
Igneous rock makes dikes and sills. Basalt or Diabese Dikes are actually usually composed of dolerite.
Yes, it can be.
Dolerite
A dolerite occurs in dikes and sills. These are dark, medium-grained igneous rocks that are typically containing olivine, plagioclase, and pyroxene.

In comparison to the slower cooled magma that created the gabbro, the dolerite has formed closer to the surface. This means that there was less time for crystal growth before it cooled into rock, resulting in the difference in crystal size between the two.
Dolerite is very rough.

Dolerite also called "Rowley Rag" can be found in Rowley Regis,West Midlands,England.
It wuz used for pounding into a rock. the dolerite ball was very. very hard.
Neither. Conglomerate is a sedimentary rock. Intrusive and extrusive are descriptive terms used to classify igneous rocks.
