What are the metallogenic epochs?
A metallogenic epoch is a period of time during which a significant concentration of deposits of one metal formed in one or more provinces. Metallogenic Provinces in relation to Plate Tectonic Setting. Interior Basins 1- Placer Gold deposits (e.g. Witwatersand) 2- Unconformity type U deposits (e.g. Athabasca sands).
What are metallogenic provinces?
A metallogenic province is the entity of mineral deposits that formed during a tectonic-metallogenic epoch within a major tectonic unit and which are characterized by related mineral composition, form of the deposits and intensity of mineralization.
What are metallogenic zones?
Metallogenic province, geographic area characterized by a particular assemblage of mineral deposits, or by a distinctive style of mineralization. The causes of formation of metallogenic provinces are not clear. Metallogenic provinces are thought to be formed also by the expulsion of pore waters from sedimentary basins.
What is metallogenic epoch of gold?
Although gold deposits are different in genetic types, ore-forming materials and geological settings, our research indicates that the accumulation and emplacement of the ore-forming materials are temporally-spatially concentrated on a large scale, and the main metallogenic epoch of Jiaodong gold deposits was …

What is meant by metallogeny?
Metallogeny, is the branch of geology that seeks to define the genetic relationship between the geological history of an area and its mineral deposits.

What is a metallogenic belt?
Metallogenic belt. A geologic unit (area) that either contains or is favorable for a group of coeval and genetically-related, significant lode and placer deposit models. With this definition, a metallogenic belt is a predictive for undiscovered deposits. Metamorphic terrane.
What is tenor in geology?
Tenor of ore is the lowest permissible metallic deposit in an ore. Any ore must contain some percentage of a metal in it. EXPLANATION: An ore is ‘naturally occurring solid material’ from which a metal or a mineral can be extracted. This metal or mineral can then be sold in the market profitably.
