Fine grained has larger crystals and coarse grained has smaller crystals
shale is fine grained
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Coarse
No, intrusive rocks are typically coarse-grained because they form from magma that cools slowly beneath the Earth's surface, allowing larger crystals to develop. In contrast, extrusive rocks, which form from lava that cools quickly on the surface, are usually fine-grained. Thus, the grain size is a key distinguishing feature between intrusive and extrusive igneous rocks.
The name of a fine-grained rock embedded with crystals and gems is called a geode. Geodes are hollow rocks that contain various crystals and minerals, often formed in volcanic or sedimentary deposits. They are prized for their unique beauty and can be cut open to reveal the dazzling crystals inside.

Porphyry cooled slowly, allowing large crystals to form within a fine-grained matrix. This slow cooling process gives porphyry its characteristic appearance of large crystals embedded in a finer grained groundmass.

If a granite rock is made of smaller crystals, it would be called fine-grained or fine-grained granite.
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
Cooling rates. A coarse-grained rock likely cooled slowly, allowing larger crystals to form, while a fine-grained rock probably cooled quickly, resulting in smaller crystals.
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.
Fine-grained
Rapid cooling of lava with tiny crystals forming results in a fine-grained texture, like that of basalt. This texture is characterized by small mineral grains that are difficult to see with the naked eye.
Large crystals found in a fine-grained rock can indicate that the rock cooled slowly, allowing the crystals to grow larger. This slow cooling process typically occurs deeper within the Earth's crust where temperatures are higher. The presence of large crystals in a fine-grained rock can also suggest that the rock underwent metamorphism, changing its original composition.
