Description

Australian dolomitic marble tiles quarried from the ancient Pilbara region of Western Australia, featuring geological formations dating 1.6-3 billion years. These premium tiles combine the aesthetic beauty of marble with enhanced physical properties of dolomite, offering superior hardness, lower porosity, and excellent weather resistance. Available in four distinctive varieties: Pilbara Green (deep green with chlorite veining), Pilbara Red (burgundy with cream veins), Austral Pearl (pearly white), and Austral Dream (cream with blue-grey movement). Suitable for flooring, wall cladding, benchtops, and external applications.

Pilbara marble formed 1.6-3 billion years ago during the Archean period, representing some of Earth's oldest exposed rock formations. The stone contains stromatolites - fossilised microbial structures that provide evidence of early life on Earth (3.4-3.5 billion years ago). Commercial quarrying began in the 1980s at Maroonah Station, with Cairns Marble Australia establishing operations in 1989. The unique dolomitic composition was discovered to provide superior hardness compared to traditional calcitic marbles. Modern extraction uses diamond wire cutting to minimise waste, with blocks shipped to facilities in Cairns and Perth for processing. The marble has been specified in landmark projects including government buildings, luxury hotels, and cultural centres across Australia. Recent sustainability initiatives include water recycling at quarries and utilisation of offcuts for aggregate production.
