Dolerite is typically found as a hypabyssal igneous rock, typically within dykes, however, it may also occur in sills, lopoliths and laccoliths. Dykes may also contain basalt instead of dolerite.

What is the hypabyssal igneous rock?

@T.Ganai.

It is a type of Igneous Rock. It's Cooling of molten magma at considerable depth.

All are different types of igneous rocks. Where Granite is a plutonic rock; Dolerite is a hypabyssal rock and basalt is a volcanic rock.

In increase order from depth igneous rocks.

Plutonic < hypabyssal < volcanic rocks.

What is the depth range of these rocks?

Praveen Kumar said: (Jun 14, 2017)  
Plutonic > 35m eg granite.
Hypabyssal < 35m eg dolerite.
Volcanic on Earth surface eg basalt.

All 3 are the examples of igneous rock.

Hypabassal rock is intrusive ignou rock which is at the shallow depth.

Dolerite, also called diabase, is a dark igneous rock intermediate in grain size between basalt and gabbro. Consisting of plagioclase feldspar and pyroxene, it is a widespread intrusive rock, quarried for crushed and monumental stone (known as "black granite").

Here granite is plutonic rock.
Basalt is volcanic rock.
Dolerite is Hypabyssal rock.

Dolerite hypabyssal is correct.

A subvolcanic rock, also known as a hypabyssal rock, is an intrusive igneous rock that is emplaced at medium to shallow depths (>2 km) within the crust, and has intermediate grain size and often porphyritic texture between that of volcanic rocks and plutonic rocks.

Granite is plutonic rock.
Dolerite is Hypabyssal rock.
Basalt is volcanic rock.
