The four I know of are: gabbro, basalt, peridotite, and dolerite.
The fine-grained equivalent of gabbro is basalt. Basalt is an igneous rock that forms from the rapid cooling of lava on the Earth's surface, resulting in smaller mineral crystals compared to gabbro.
If you are referring to igneous rocks, they are classified as mafic.
Examples of mafic intrusive igneous rocks include gabbro, diabase, and dolerite. These rocks are typically dark in color and are composed predominantly of minerals such as pyroxene and plagioclase feldspar. Mafic rocks form from magma that is rich in iron and magnesium, with low silica content.
Dolerite is not naturally magnetic. It does not possess magnetic properties on its own.

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.

The counterpart of Granite is Rhyolite,the counterpart of Gabbro is Basalt. Gabbro is mafic(Dark coloured) ,Granite is felsic (light coloured) Granite forms from magma of Granitic composition while Gabbro forms from magma of Basaltic composition.
Gabbro.
Examples of mafic intrusive igneous rocks include gabbro, diabase, and dolerite. These rocks are typically dark in color and are composed predominantly of minerals such as pyroxene and plagioclase feldspar. Mafic rocks form from magma that is rich in iron and magnesium, with low silica content.
Dolerite is very rough.
No, gabbro is a non-foliated igneous rock, meaning it does not have a layered or banded appearance like foliated rocks. Gabbro forms deep underground as magma cools slowly and solidifies, resulting in a coarse-grained texture without any alignment of minerals.
Gabbro has a dull to shiny luster, depending on the mineral composition and how the light reflects off its surface. It typically has a more mafic composition with minerals like pyroxene and amphibole, which can create a dull appearance, but variations in mineral content can lead to some sections of gabbro having a shinier luster.
