That rock I believe is Mica

Biotite mica Biotite mica can be easily identified by its dark brown to black color that is a result of the high ferro-magnesium content of the mineral. It is a common rock forming mineral that is found in granite, syenite and other igneous rocks. It is also found in metamorphic rocks such as gneisses and schists

Step-by-step explanation:

As a naturally-forming silicate mineral, mica occurs in igneous rock, which consists of layers of volcanic material. At this stage, mica is crystal in form and is mined to extract it.  The richest natural sources of mica are coarsely grained igneous rocks known as pegmatites
