The letter "g" is pronounced with a hard "g" sound, while the double letter "s" is pronounced as a voiceless alveolar sibilant. The final letter "n" is silent. "Gossan" refers to a rusty, iron-bearing rock found on top of a mineral deposit, often an indicator of valuable minerals below.

GOSSAN Meaning and Definition

1. Gossan refers to a geological term used to describe an oxidized outcrop or weathered surface of ore deposits that contain minerals, especially sulfide ores. The term is primarily used in the field of economic geology, particularly in mining and mineral exploration.

   Gossan forms due to the weathering of exposed sulfide minerals, which generally occur in hydrothermal deposits such as those related to volcanic activity or hot springs. As these minerals are exposed to air, water, and other weathering agents, they begin to oxidize, resulting in the formation of iron oxide, hydroxide, or other compounds. This oxidative process also leads to the release of metallic ions and sulfuric acid, resulting in the characteristic rusty appearance of gossan.

   The presence of gossan can serve as an indication of the potential presence of valuable ore deposits beneath the weathered surface. It often contains secondary minerals, such as limonite and goethite, which can be associated with valuable metals like gold, silver, copper, or zinc. Furthermore, gossan can provide insights into the composition and quality of the underlying ore bodies.

   In summary, gossan is a weathered surface of ore deposits consisting of oxidized minerals and often exhibiting a rusty appearance. Its presence can be indicative of valuable metallic ore beneath the surface, making it an important indicator for mineral exploration and mining activities.

2. Among Cornish miners, the peculiar ferruginous condition of the top of a vein near its outcrop, considered to be very strongly indicative of the lode below; ferruginous quartz.

Etymology of GOSSAN

The word "gossan" is derived from the Cornish word "gos", meaning "waste" or "rubbish". The term was initially used in Cornwall, England, where large deposits of metal-rich minerals were found near the surface. These mineral deposits were typically weathered and oxidized, resulting in the formation of conspicuous reddish-brown or yellow rock formations known as "gossans". The name "gossan" was therefore given to these weathered mineral veins rich in iron, copper, zinc, and other valuable metals. Over time, the term has been adopted and used more broadly in the field of geology to refer to any oxidized outcrop or capping over an ore deposit, regardless of its location.
