Geologically, the Mizo Hills are considered a part of the Rakhine (Arakan) Mountains system. This mountain arc, which stretches northward from Myanmar into India, consists of a series of compact, parallel ridges formed of sandstone, limestone, and shales.1

The Mizo Hills specifically form part of the north Arakan Yoma system. Together with the Chin Hills, the Naga Hills, and the Patkai range, they constitute a continuous mountain arc that defines the north-south trend line of the region. This interconnected system acts as a significant geographical feature, historically serving as a barrier to east-west movement between the Indian subcontinent and Myanmar.234
