Because both crystallize at similar temperatures and pressures according to Bowen's Reaction Series.
Olivine... if you can find on the internet the "Bowens Reaction Series" paper, it will tell you that Olivine is the first to crystallize

Magma solidifies into a combination of minerals that are collectively called igneous rock. Minerals common in igneous rock are potassium feldspar, plagioclase feldspar, muscovite and biotite mica, quartz, hornblende, olivine, and magnetite.

None, you don't get quartz and olivine in the same igneous rock.
scoria
A dolerite occurs in dikes and sills. These are dark, medium-grained igneous rocks that are typically containing olivine, plagioclase, and pyroxene.
No. Calcite is not an igneous mineral. Basalt primarily consists of pyroxines and plagioclase with some olivine.
Gabbro.
Igneous rocks are identified by first looking at the color index. Felsic igneous rocks contain mostly potassium feldspar. Intermediate igneous rocks contain mostly plagioclase feldspar. Mafic igneous rocks contain pyroxene, olivine, and plagioclase feldspar. Ultra mafic igneous rocks contain mostly olivine. Then igneous rocks are identified based on texture. For example, the texture of igneous rocks can be aphanitic, pegmatitic, phaneritic, glassy, vesicular, etc.
