Igneous rock has interlocking grains with no specific pattern.

A rock that has interlocking grains with no specific pattern is known as a non-foliated rock. Examples include quartzite and marble. These rocks form from the recrystallization of minerals under high pressure and temperature conditions, resulting in interlocking grains without a preferred orientation.
All rocks have grains, the grains referring to particles of rock or mineral crystals. Rocks with visible grains include granite, gneiss, marble, gabbro, and quartzite.
Non-foliated rock, such as marble, has interlocking grains with no specific pattern due to the recrystallization process that occurs under high pressure and temperature, obscuring any original texture or layering. This results in a homogeneous, fine-grained appearance without distinct foliation or banding.
Interlocking grains refer to the irregular and intertwined growth patterns of mineral grains in a rock. This texture indicates a strong bond between the grains and can enhance the overall strength and durability of the rock. Interlocking grains are commonly found in metamorphic rocks such as gneiss and marble.
Granite is a type of igneous rock that typically has interlocking mineral grains without visible gaps. These interlocked grains give granite its characteristic strength and durability, making it a popular choice for countertops and building materials.
Granite typically has a coarse-grained texture, with interlocking crystals that are visible to the naked eye. The grains in granite are typically irregular in shape and can vary in size, depending on the specific mineral composition of the rock.
Granite typically has a coarse-grained texture, meaning that the individual mineral grains are large enough to be seen with the naked eye. The grains in granite are usually interlocking, giving the rock its strong and durable structure.
