A granite rock made of smaller crystals would still be called granite.

The size of the crystals in a granite rock is a factor in its texture, not its classification. Here's why:

* Granite is defined by its mineral composition, primarily quartz, feldspar, and mica.

* Texture refers to the size, shape, and arrangement of the crystals.

* Fine-grained granite has smaller crystals, while coarse-grained granite has larger crystals.

So, while the size of the crystals can influence the appearance and specific name of the granite (e.g., "fine-grained granite"), it doesn't change its fundamental classification as granite.
