Dolerite is coarse grained variety of basalt, if present in the dorm of a dyke (discordent igneous body), it is called a dolerite dyke.

No, it light cannot travel through Dolerite (A.K.A Diabase). It is igneous, grey in colour and rich in magnesium and iron, and therefore opaque. Hope this helps. Pingk
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 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.
Igneous Rock :)
A dolerite occurs in dikes and sills. These are dark, medium-grained igneous rocks that are typically containing olivine, plagioclase, and pyroxene.

Granite is felsic means having more than 65% SiO2 whereas dolerite is mafic having 45 to 52 SiO2.
