The Carlin Unconformity or Carlin Trend is a geologic feature in northeastern Nevada which represents a period of erosion or non-deposition likely associated with a collision between a tectonic crustal block called a terrane and the North ...
Production from the trend surpassed 50,000,000 troy ounces (1,600 t) of gold in 2002. The Carlin and other mines along the trend pioneered the method of open-pit mining with cyanide heap leach recovery that is today used at large low-grade gold mines worldwide.

The Goldstrike mine adjoins Newmont Mining's Carlin mine complex. Goldstrike is northwest of the Carlin mine on the Carlin Trend.
