Rockhounding in Nagaland
Nagaland currently has 61 sourced map records in this explorer. Nagaland has unusually varied rockhounding geology, especially ophiolite-hosted magnetite/chromite/PGE minerals, limestone, coal-bearing sedimentary rocks, building stone and a DGM-documented chalcedony–agate occurrence near Layoti nallah. However, official sources mostly describe exploration blocks, mineral resources or regulated extraction, so this guide keeps those records non-navigable unless site-specific recreational access is independently established.

Why Nagaland is important for ophiolite minerals, limestone and chalcedony–agate geology
The eastern Naga Hills Ophiolite hosts serpentinized ultramafic rocks, magnetite, chromite and associated Ni-Co-Cr-Ti-V/PGE mineralization, while Kiphire and Phek contain major limestone resources. Mokokchung and other western/northern districts contain Tertiary coal-bearing Barail rocks. DGM also documented chalcedony and agate boulders along Layoti nallah, probably derived from quartzitic terrain near New Thewati. These are strong geological records, but Nagaland’s mineral-concession and coal rules mean occurrence must be separated from permission to collect.

Access and collecting rules
Nagaland combines Tertiary sedimentary coal-bearing belts in the west and north with the Naga Hills Ophiolite along the east. Official DGM work documents Ni-Co-Cr-bearing magnetite, chromite/PGE-bearing ultramafic rocks, extensive limestone, coal, building stone and a chalcedony–agate stream-boulder occurrence. Mineral-resource and extraction contexts are regulated and are not public collecting permissions.
