Publikováno v: Georesursy, Vol 26, Iss 1, Pp 38-51 (2024)

On the example of the Novo-Ursk tailing dump (Salair Ridge), the typomorphic characteristics of barite are considered. It was found that in the dumps, in addition to residual barite from pyrite-polymetallic ores, there are its authigenic varieties. O

Possible links with methane seepage and gas hydrate dynamics inferred from authigenic barite records in the northern south china sea

Autor: Junxi Feng, Min Luo, Jinqiang Liang, Shengxiong Yang, Hongbin Wang, Niu Li, Xiaoming Sun

Publikováno v: Frontiers in Earth Science, Vol 10 (2022)

Numerous methane seepage events occurred in periods of low or falling sea level since 330 ka BP, which is attributed to decrease in hydrostatic pressure and subsequent gas hydrate dissociation in the northern South China Sea (SCS). The seepage intens

Autor: Roberto H. Gwiazda, Charles K. Paull, David W. Caress, Christina Marie Preston, Shannon B. Johnson, Eve M. Lundsten, Krystle Anderson

Publikováno v: Frontiers in Marine Science, Vol 6 (2019)

High-resolution mapping with an autonomous underwater vehicle (AUV) of a section of the San Clemente fault, offshore Southern California, reveals the largest documented cold-seep-associated barite deposits discovered to date. Although barite deposits
