A dolerite occurs in dikes and sills. These are dark, medium-grained igneous rocks that are typically containing olivine, plagioclase, and pyroxene.
Dolerite is very rough.
Dolerite is not naturally magnetic. It does not possess magnetic properties on its own.
A dolerite dyke is a sheet-like igneous intrusion that cuts across the surrounding rock formations. It is composed mainly of medium-grained dolerite rock that solidified from magma that intruded into existing rock layers. Dolerite dikes are common in areas with volcanic activity or tectonic movement.
It wuz used for pounding into a rock. the dolerite ball was very. very hard.
Igneous Rock :)
Dolerite is a type of volcanic rock that is commonly found in dikes and sills. It is formed from the slow cooling of magma underground. Dolerite can be found in various regions around the world where there has been volcanic activity in the past.

Dolerite hills form from the cooling and solidification of magma that intrudes into existing rock layers and then crystallizes underground. Over time, erosion removes the overlying sedimentary rocks, exposing the more resistant dolerite, which typically manifests as rugged hills or outcrops. The process involves geological uplift and weathering, which contribute to the formation of distinctive topographies in areas where dolerite is prevalent.
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
Light can pass through dolerite, although the amount of light that is transmitted will depend on the thickness and composition of the rock. Dolerite is a dark igneous rock that is typically fine-grained, so it may not be transparent but light can still penetrate it to some extent.
The four I know of are: gabbro, basalt, peridotite, and dolerite.
