It is likely to have a coarse-grained texture.
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.

The texture of intrusive igneous rocks is phaneritic, which is characterized by coarse-grained large crystals that are visible to the naked eye. The texture of volcanic rocks, meanwhile, is porphyritic, which is characterized by fine-grained crystals.
Coarse grained igneous rock is formed from the slow cooling of magma.
Igneous rocks are formed by the cooling of lava (above Earth's surface) or magma (below). Rocks in general are classified by their mineral composition, texture, and origin. Igneous rocks all have the origin of molten material, there are two categories within this: intrusive and extrusive. Intrusive rocks formed below earth's surface and extrusive rocks above. Their mineral composition varies greatly and depends on each individual rock. The classification of igneous rocks in texture is linked to their origin. The texture of a rock is defined by its grain: can you see and feel the little rocks that make it up? If you can, that rock has a coarse grain, if you can't see the bits, it is fine grained. Intrusive igneous rocks are usually fine grained; extrusive, coarse grained.
== == Extrusive igneous rocks are formed from the solidification of lava on or above the surface. Rapid cooling from exposure to air or water results in rapid crystallization of their component minerals, normally creating a fine grained texture as opposed to intrusive igneous rocks which have a coarser texture. Examples of extrusive igneous rocks would include obsidian, pumice, basalt, and rhyolite.
They are made slowly. This is why they have a coarse-grained or rough texture. On the other hand there are extrusive igneous rocks, which are formed quuickly. These have a fine-grained or smoother texture. Intrusive rocks have more time to cool, so the mineral crystals can grow bigger, but extrusive rocks have lss time for their mineral crystals to grow.Igneous rocks form when magma cools and hardens.
Coarse-grained igneous rocks are formed when magma cools slowly deep inside the Earth. Creating big crystals in them.
