Druse formed by Calcite crystals of a marked reddish-orange color, deeper on the edges of the crystals, with the centers of the faces of the cubes much more translucent. Twinned and with good luster, they are on a matrix with limonite remnants.
Dyserth Quarry exposes Lower Carboniferous limestones and dolomites forming part of the northern carbonate belt of the Clwydian Range. These units, affected by fracturing and low-temperature hydrothermal circulation, host small fissure- and cavity-type mineralisation with secondary zinc, iron, and copper species, typical of limestone quarries across northern Wales.
