The region described here lies inland from the coastal towns of Cairns and Townsville in North Queensland, and extends west 250 miles to Croydon: it is rectangular and has an area of about 37,000 square miles (PI. 38). The map area extends from longitude 145° 30' E. to longitude 142° 10' E.: the most northerly point is at latitude 16° 20' S. and the southern boundary is along latitude 20 00' S. It includes the whole of the Clarke River, Georgetown, Einasleigh, and Atherton 1: 250,000 Sheet areas, and parts of the Mossman, Normanton, Red River, Croydon, and Gilberton Sheet areas. The first geologists visited the area about 1870 after the discovery of economic deposits of gold and later of tin, copper, tungsten, and silver-lead. Most of the early geological mapping was carried out in the mineral fields, although a few syntheses of the regional geology were made. In 1956, a combined party of the Bureau of Mineral Resources and the Geological Survey of Queensland commenced mapping on the Georgetown, Einasleigh, Gilberton, Clarke River, and Atherton 1: 250,000 Sheet areas, under the leadership of D.A. White (BMR). This survey continued each year and by 1963 had extended north to the Cooktown/Cape Melville area. I was a member of the survey in North Queensland from 1957 to 1963.
