WLC site description

Part of the Clackmannan Group sites

Other designations: WS (Silvermines Quarry); HPWG (Bathgate Hills, Knock, Knock A); AGLV

Hilderston Silver Mine Quarry is located 200 m north of The Knock and approximately 500 m south-east of Cairnpapple Hill. Although the Petershill Limestone is no longer visible in the Silver Mine Quarry, a 3–4 m section through the overlying mudstones, siltstones and sandstones sediments is seen (Figure 98). These display an excellent coarsening upward sequence with good sedimentary structures, including ripples and burrowing (Figure 99).
