Limestone is not formed from magma; it is a common sedimentary rock.
However it may be worth noting that there is a rare form of igneous rock known as Carbonatite which is formed predominately from carbonate minerals and may be confused with Marble, however it is never described as Limestone.

BASALT
Rhyolitic magma, high in quartz and feldspar. Forms granite underground, rhyolite above ground.
igneous rock
Mafic igneous rock. ( due to Ferromagnesian minerals).
When limestone is under high pressure from overlaying rock layers and is heated by magma it can form marble.
When a sedimentary rock or any other rock kind melts, it becomes magma and when it sollidifies it forms an igneous rock.
Sandstone and limestone and obsidion
The metamorphosed limestone will most likely be a skarn or marble, both formed from contact with an intruding granitic magma.
igneous rock
When magma cools, it forms igneous rock.
Rhyolitic magma, high in quartz and feldspar. Forms granite underground, rhyolite above ground.
The rock which will form will be marble because the limestone undergoes metamorphosis (partial recrystallisation).
Igneous rocks
IT IS A Sheild volcano
limestone forms from skeletons and shells
Intrusive Igneous Rock.
