The texture referring to rocks composed mainly of mineral and volcanic fragments is called clastic.

Here's why:

* Clastic refers to rocks formed from fragments of other rocks. These fragments are often called clasts.

* Mineral fragments can come from pre-existing rocks that have been weathered and eroded.

* Volcanic fragments are pieces of lava or volcanic ash that have been ejected during eruptions.

Examples of clastic rocks:

* Sandstone: Composed of sand-sized fragments.

* Conglomerate: Composed of gravel-sized fragments.

* Breccia: Similar to conglomerate, but with angular fragments.

* Tuff: Composed of volcanic ash fragments.
