Submitted by Daniel Gregory on
Thank you for the presentation. You mention that there are enrichment in Cu, P, V and Ag. How enriched are they (~ppm) and in what minerals are these elements held? Do they form their own minerals or are they found as accessory elements in other minerals?

Submitted by Akira Usui on
Is your hydrothermal manganese (probably modern) oxide precipitate of different chemistry or mineralogy from other preported precipitates, or close to those reported elsewhere in the active areas?

Submitted by Kira Mizell on
What is the scale of these hydrothermal deposits? Is all of the Mn mineralization on the smaller mm-cm scale as replacement or precipitation in the other various rock types? Or are there hand-sized or larger pieces of hydrothermal Mn?

Submitted by Kira Mizell on
Is there any spatial relationship between the precipitation of the Mn oxide minerals and distance from the ridge?
