Hi guys...found this rock outside. Doesn't look like much, but just wondering if anyone here knows what this might be.

Thanks.

Looks like Mica, biotite possibly?

Biotite Schist?

 

[Eu_citzen]

Schist has a layered structure, often as a horizontal plane. Take a look.
Could just be a mass of smaller biotite crystals, also.
