Scientific Objectives:
The working group aims to address the following scientific problems:

1) Understand the geological factors that contribute for the formation, distribution and preservation of seafloor massive sulfide deposits, including geological and tectonic setting;
2) Characterize the geological, geophysical and geochemical signatures that allow for the detection and documentation of inactive and buried sulfide deposits at Mid-Ocean Ridge-axis or off-axis settings;
3) Identify multi-scale observations that could be used to predict past, present and possibly future hydrothermal deposit formation;
4) Determine the spatial distribution pattern and resource potential of mid ocean ridges with various spreading rates;
5) Understand the timing and variations in the geological drivers for hydrothermal activity across mid-ocean ridge segment-scale systems;
6) Determine the dimensional structure and metal inventory for mid-ocean spreading ridges based on long-term heat flow, volcanism, fluid fluxes and sedimentation rates;
7) Understand the processes of seafloor and sub-seafloor sulfide formation, weathering, and their impact on crust-to-water column exchange in metals.

Short report from the 1st workshop of the the Working Group on Seafloor Massive Sulfides Resource along MOR

From September 19th to 22nd, 2019, the 1st international workshop organized by the InterRidge Working Group on SMS resource along MOR was held at Hangzhou, China with a great success. More than 150 SMS related scientists and students from worldwide participated in this workshop and had in-depth discussion with focus on the theme of "hydrothermal ore-forming processes". During the three days, the participants exchanged ideas in various ways – primary/early career presentations, posters, plenary/break-out brainstorm and so on.

Details about the IR workshop on "Hydrothermal Ore-forming Processes" in Hangzou (China)

The 1st international workshop organized by the InterRidge Working Group on Seafloor Massive Sulfides Resource along MOR is going to be held at Braim Canal Hotel between 19 and 22 September, 2019, in Hangzhou, China. The theme is “Hydrothermal ore-forming processes and the fate of SMS deposits along slow and ultraslow spreading MOR”.

Call for abstracts for the upcoming "InterRidge Workshop on Hydrothermal Ore-forming Processes"

We have a pleasure to announce the call for abstracts for the upcoming "InterRidge Workshop on Hydrothermal Ore-forming Processes", organized by the InterRidge Working Group on Seafloor Massive Sulfides Resource along MOR between 19 and 21 September 2019, in Hangzhou, China. The overall theme of the workshop will be focused on hydrothermal ore-forming processes and the fate of Seafloor Massive Sulfide (SMS) deposits along slow and ultraslow spreading mid-ocean ridge system (MOR).
