Geographic Location

Loanhead Quarry sits in the scenic countryside of North Ayrshire, just 2 km north of Beith and 20 km from central Glasgow. Beith is a small town with nearby settlements like Lochwinnoch (3.7 km) and Kilbirnie (5.4 km), making it accessible yet tranquil for mineral enthusiasts.

Minerals Produced

The quarry is famous for a variety of minerals, including rare Greenockite (orange cadmium sulfide) often found in Prehnite matrices, and prized zeolites like Heulandite and Thomsonite. Other minerals include Andradite, Grossular, Calcite, Quartz, and Silver, appealing to collectors for their beauty and rarity.

Geological Structure

Excavated in basalts of the Clyde Plateau Lavas, formed over 300 million years ago, the quarry features three lava flows up to 800 meters thick. A 15-meter-wide dolerite dyke separates active areas. Minerals formed through hydrothermal alteration of primary minerals like olivine, creating secondary treasures in vesicles and joints.

Mining History

Loanhead Quarry is still active, with Tarmac Roadstone (Scotland) Ltd operating the north-eastern part. Since 2012, the south-western section has been a landfill managed by W.H. Malcolm Limited, using inert soils, reflecting its ongoing industrial role.
