Arsenic-bearing pyrite, known as arsenian pyrite, is the most important and in
\nmany cases the onlyAu-bearing mineral in Carlin-type and some epithermal deposits.
\nBecause it incorporates Au from solutions that are undersaturated with respect to native
\nAu, precipitation of arsenian pyrite is the key to removal of Au from solution and
\nformation of an economic deposit. Recent micro-scale studies of arsenian pyrite from
\nawide range of deposits have provided new information on its role as a host forAu and
\non the nature and significance of its growth zoning. Two types of arsenian pyrite have
\nbeen recognized so far:<\/p>\n
1) As1\u2013-pyrite, in which As1\u2013 substitutes for S; it is found in Carlin-type and
\nlow-sulfidation epithermal deposits that formed in reduced hydrothermal systems.<\/p>\n
2) As3+-pyrite, in which As3+ and possibly other forms of oxidized As substitute for
\nFe; it is found in high-sulfidation epithermal deposits that formed in oxidized hydrothermal
\nsystems.<\/p>\n","protected":false},"featured_media":4493,"comment_status":"closed","ping_status":"closed","template":"","meta":{"pmpro_default_level":""},"product_cat":[154],"product_tag":[],"_links":{"self":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product\/2462"}],"collection":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/comments?post=2462"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media\/4493"}],"wp:attachment":[{"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/media?parent=2462"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_cat?post=2462"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.gsnv.org\/wp-json\/wp\/v2\/product_tag?post=2462"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
