False

Explanation:

The galactic disk is divided into 2 zones, the thick and thin zones, related to the age since their formation, and structure.

The thin disk is composed of younger stars, dust, and gas.

The thick disk (also called stellar halo) is composed of older stars. It was formed at an earlier stage of the galaxy formation and thus has less heavy elements.
