The spatial and temporal relationship between petroleum and ore deposits has attracted the attention of scientists since the 1960s, when a connection was determined between oil-gas formation processes and ore-forming processes, which led to the formation of Pb-Zn Mississippi-type deposits, Carlin-type gold deposits, and stratiform copper deposits. These studies concluded that there is a paragenetic relationship between petroleum fluids and ore mineralization. To date, studies concerning the relationship between se...

Hydrothermal processes, particularly hydrothermal eruptions, play a key role in forming epithermal gold-silver deposits. Such deposits, first described by White [1] and Lloyd [2], are found in both active and ancient hydrothermal systems [3]. These processes are linked to geothermal systems, volcanic activity, and fluid circulation, but their exact mechanisms and influence on metal concentration remain debated. This study examines the role of hydrothermal eruptions and key factors (temperature, boiling, chemical c...

The paper considers processes of ore formation. This concerns complex dynamic natural objects, depending on polygenic geological phenomena, mutually interacting and forming a single mineral formation environment. Development of ore-forming systems is connected not only with the natural evolution of thermodynamic parameters, but also with physical-chemical properties and composition of ore-bearing deposits, state and character of manifestation of tectonic structures, such as field strength, degree of tectonic trans...

The paper provides comparative characteristics geodynamic situations and of related intrusive series. Discussed are cases of alternation of such granitoids in time, their connection in space and relation to collisional processes. I-granites form extended gabbro-diorite-granodiorite-sodium and potassium-sodium granite series with gradual increase of the role of silica and potassium in the final products. Differences in the petrochemical composition of pre- and late collision of I-granites are conditioned by the sub...

Gold deposits in black shale type have huge reserves of hard-gold. The prevailing part of reserves of native gold is in carbonaceous terrigenous deposits in Russia. These deposits are represented by objects of various scales - from small to unique (In Russia пїЅ Olimpiada, Nezhdanin, Natalkin, May; in Uzbekistan пїЅ Muruntau, Kokpatas, Zarmitan, Daugyztau, Amantaitau; in Kazakhstan пїЅ Bakyrchik; in Tajikistan пїЅ Chore; in Kyrgyzstan пїЅ Kumtor; in the United States пїЅ Mather Lod; in Australia пїЅ Bendigo, Olymp...
