Granite.
Solidification of a coarse-grained igneous rock usually occurs deep beneath the Earth's surface, in a magma chamber or intrusive setting. Here, the slow cooling allows for the formation of larger mineral crystals, resulting in a coarse-grained texture. Examples of coarse-grained rocks include granites and gabbros.
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
Course igneous rock
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
Granite is a coarse-grained igneous rock, meaning it is made up of large interlocking crystals. These crystals form as the magma cools slowly beneath the Earth's surface, allowing for the growth of larger grains rather than small ones.

Solidification of a coarse-grained igneous rock usually occurs deep beneath the Earth's surface, in a magma chamber or intrusive setting. Here, the slow cooling allows for the formation of larger mineral crystals, resulting in a coarse-grained texture. Examples of coarse-grained rocks include granites and gabbros.
Anorthosite typically has a coarse-grained texture, with individual mineral grains that are easily visible to the naked eye. It often appears as a mottled combination of white, gray, and black minerals, with a crystalline structure that can exhibit cleavage planes.
fine grained
Gneiss is course grained but it has a fabric.
Intrusive igneous rocks form underground from magma that cools slowly, resulting in coarse-grained textures. They have large mineral crystals visible to the naked eye, such as feldspar, quartz, and mica. Examples include granite, diorite, and gabbro.
G
No, granite is a coarse-grained igneous rock that is made up of minerals like quartz, feldspar, and mica. Glassy igneous rocks, like obsidian, form when molten lava cools quickly on the surface, resulting in a smooth, glass-like texture.
shale
Normally the flow of water through a course grained material will be faster than through a fine grained material as the pore spaces between the grains tend to be larger.
You can look at the rock texture.If the crystals are Large enough to be visible with your naked eye without stressing it the the texture is likely to be either medium coarse grained or course grained which is an indication that it is Intrusive.The opposite is forExtrusive
