No. Calcite is not an igneous mineral. Basalt primarily consists of pyroxines and plagioclase with some olivine.
Granite - coarse grained. Basalt - fine grained.
Basalt is an igneous rock . . . it is pretty much hardened lava.
Basalt is considered igneous because it forms when mafic lava cools at Earth's surface.

While it is molten it is above the Curie temperature and is not magnetic, as it cools below this temperature the ambient magnetic field becomes "frozen" into the basalt.
The seafloor spreads apart, creating new rocks that record magnetic orientation. Small grains of magnetite on the volcanic basalt (ocean floor) have magnetic properties.

Many rocks have magnetic properties (are capable of being magnetized, are magnetic or are attracted by a magnet) derived from magnetic minerals in their composition like magnetite, hematite, and ilmenite. The most well known magnetic rock is the lodestone, which is comprised mainly of magnetite.
Basalt is on of the many rocks that is black, obsidian (a volcanic glass) is another.

The address of the Basalt Rld is: 14 Midland Ave, Basalt, 81621 8305
the data gathered from continental basalt flows allowed scientists to construct the geomagnetic time scale. Continental basalt flows were used to construct the geomagnetic time scale. long term changes in earth's magnetic field are called epochs. short term changes are called events :D
That rock was not Basalt, it was different. This is not a diamond, just a normal Basalt.
