Anyone know what type of rock this is? Has black shiny pieces in it. Found in Central California.
Thanks

Looks like some type of metal ore.

Another possibility is the small black shiny pieces are Benitoite and the other is just the matrix they formed in,I live in central valley, If I was you I would research what mines are close to area you found it in.Current mining and mines that are closed.

If you have a black light Benitoite gives off a blue illumination under a black light.
