The
Arbuckle Mountains are an ancient mountain range in south-central
Oklahoma in the
United States. They lie in
Murray,
Carter,
Pontotoc, and
Johnston counties. The
granite rocks of the Arbuckles date back to the
Precambrian 'Era' some 1.4 billion years ago which were overlain by
rhyolites during the
Cambrian Period. The range reaches a height of 1,412 feet above sea level. According to the U.S. Geological Service (USGS):
The Arbuckles contain the most diverse suite of mineral resources in Oklahoma: limestone, dolomite, glass sand, granite, sand and gravel, shale, cement, iron ore, lead, zinc, tar sands, and oil and gas; all these minerals are, or have been, produced commercially.
