Precambrian Gold: Unveiling Pecos Mine's Ore Deposits

A study of metallogenic relationships among precambrian gold deposits provides some broad new insights regarding genetic problems. Three types of deposits are important: Mar 1, 2018 · two events of gold metallogeny are identified in the wutai greenstone belt. Most of the precambrian gold deposits were eroded during the later complex tectonic process. The pecos mine is largest of these deposits in new mexico.

The pecos ores were probably deposited by hot metalliferous fumarolic solutions on the precambrian sea floor. The nature and stratigraphic suc­cession of various ore types are. Gold deposits suggests that the entire lithosphere may be involved in the genesis of deposits (libby et al. Anomalous amounts of silver and/or gold have been identified in 153 mining districts or prospect areas of new mexico. Production from most of these occurrences has been small;
