Fe–Si-oxyhydroxide deposits at a slow-spreading centre with thickened oceanic crust: The Lilliput hydrothermal field (9°33′S, Mid-Atlantic Ridge)
Vesselin M. Dekov,Sven Petersen,C.-Dieter Garbe-Schönberg,George D. Kamenov,Mirjam Perner,Ernő Kuzmann,Mark Schmidt +6 more
TL;DR: In this paper, the Lilliput hydrothermal field was studied and the authors found that the main deposit-forming elements, Fe and Si, appear to be partially controlled by live microbes and exuded organic compounds.

Geochemistry of vent fluid particles formed during initial hydrothermal fluid–seawater mixing along the Mid‐Atlantic Ridge
Verena Klevenz,Wolfgang Bach,Katja Schmidt,Michael Hentscher,Andrea Koschinsky,Sven Petersen +5 more
TL;DR: In this article, the authors present geochemical data of black smoker particulates filtered from hydrothermal fluids with seawater-dilutions ranging from 0-99% and show that the dominance of sulphide minerals (Fe, Cu, and Zn sulphides) in all samples taken at different hydro-thermal sites on the Mid-Atlantic Ridge is attributed to differences in fluid chemistry.

A global database of seafloor hydrothermal systems, including a digital database of geochemical analyses of seafloor polymetallic sulfides

TL;DR: Open Files as mentioned in this paper is a series of documents that are available to the public in advance of formal publication, and act as a repository for relevant supporting data that are referred to in published reports, geared towards specialists (mining industry, land-use planning, geoscience students).

PGE fractionation in seafloor hydrothermal systems: examples from mafic- and ultramafic-hosted hydrothermal fields at the slow-spreading Mid-Atlantic Ridge
TL;DR: The distribution of platinum group elements (PGEs) in massive sulfides and hematite-magnetite±pyrite assemblages from the recently discovered basalt-hosted Turtle Pits hydrothermal field and in sulfide samples from the ultramafic-based Logatchev vent field both on the Mid-Atlantic Ridge was studied and compared to that from selected ancient volcanic hosted massive sulfide (VHMS) deposits.

Atacamite and paratacamite from the ultramafic-hosted Logatchev seafloor vent field (14°45′N, Mid-Atlantic Ridge)
Vesselin M. Dekov,Tanya B. Boycheva,Ulf Hålenius,Sven Petersen,Kjell Billström,Jens Stummeyer,George D. Kamenov,Wayne C. Shanks +7 more
TL;DR: In this article, the authors provided new details on the mineralogy and geochemistry of these basic cupric chlorides and showed that they are ubiquitous minerals associated with Cu-rich massive sulfides at the Logatchev hydrothermal field (Mid-Atlantic Ridge).
