RB 77/00074 Seismic refraction investigations in the Polda Coalfield.
A seismic cross-section along the Lock-Tuckey portion of the Polda Basin shows that bedrock is between 600 m and 900 m deep. Bedrock probably, consists of either Mt. Wedge type grits and con-glomerates or weathered crystalline basement. The basin...-
