"The Lewisian complex or Lewisian gneiss is a suite of Precambrian metamorphic rocks that outcrop in the north-western part of Scotland, forming part of the Hebridean Terrane. These rocks are of Archaean and Paleoproterozoic age, ranging from 3.0–1.7 Ga. Rocks of the Lewisian complex were caught up in the Caledonian orogeny, appearing in the hanging walls of many of the thrust faults formed during the late stages of this tectonic event."
Andy Laffan thinks in 3 dimensions, after a career in interior design, space planning, visualisation and technology he has now settled in the Outer Hebrides to develop his own sculptural practice. "The geology of these remote islands has always interested me, and the chance to explore sculptural ideas and work with some of the oldest rocks in the UK was a key part of my decision to relocate to the Isle of Lewis".
