Petrography and physico-mechanical (dimension/building-stone) assessment of the Nikanai Ghar Formation marble ('Bando Obo marble') near Swabi Town (~32 deg 36' N; Swabi-Mardan Road). Marble is calcite-dominated and divided by texture into fine-, medium- and coarse-grained (equi-granular to sub-equi-granular) varieties. Geotechnical tests (UCS, UTS, specific gravity, shear strength, porosity, water absorption) show strength varying with texture - the fine-grained sample has the highest UCS (~21.8 MPa) - evaluating the unit as a building/dimension stone.

- Geological significance: Afrasiab et al. (2024): petrography of the Nikanai Ghar Formation marble ('Bando Obo marble') near Swabi Town (Swabi-Mardan Road, ~32 deg 36' N) confirms a calcite-dominated marble, divided by texture into fine-, medium- and coarse-grained (equi-granular to sub-equi-granular) varieties. A Lower-Swat/Swabi exposure additional to the curated Jafar Sar type area.
- Economic importance: Afrasiab et al. (2024): physico-mechanical testing (UCS, UTS, specific gravity, shear strength, porosity, water absorption) evaluates the Nikanai Ghar marble at Swabi as a building/dimension stone; strength varies with texture, the fine-grained variety having the highest unconfined compressive strength (~21.8 MPa). Records an economic (dimension-stone) use for the unit.
