Moore Subject: Mineral evolution data resources Flag Status: Flagged Dear Josh et al., Wow, what a great trip to Tucson last week! I am so impressed at the progress you and your team are making in developing the database. Entirely new areas are opening up to us. It's very exciting, I hope as much for you as it is for me. I wanted to collect my thoughts on what's happening and priorities. Here are a few of the projects that are in the works. 1. It's great to see the work on cobalt minerals, especially with Emily and Kristen's help. Once I nail down the numbers of localities for the rare Co minerals then I'll finish that paper in a few days. Lots more to do on cobalt. [By the way, Paul and Eli, I agree that the focus of your paper is very different, but doing the cobalt mineral evolution and ecology papers first completes something I started 3 years ago and lays important ground work for the next stage of integrating biochemistry and geochemistry.] 2. Mihai and Derek are making great strides with Josh to incorporate paleotectonic data. If we can integrate those data with GPlates and the mineral evolution database then we will have an amazing opportunity for visualization and discovery. 3. Shaunna and Tanya (I don't have her email address; please provide) will be tackling the big REE mineral project as a core part of Shaunna's PhD thesis. I see that effort supported more by my Sloan and private foundation funds, rather than Keck, but the synergies are obvious. We'll need to confer soon about the best strategies for moving that effort along. 4. Over the next week I will work with Dan Hummer to put together a very specific proposal for a 3D Klee diagram that begins with maybe 20 x 20 x 20 compositional elements and matrix elements that reflect coexisting compositions. I'm very intrigued by using oxidation states of different metals and anions, as opposed to just elements. Downside is that we can't empty Dan's crustal abundance approach; up side is we should see more redox-related correlations and we can do that for coexisting oxidation states over different time intervals. I feel that this is a great opportunity to introduce a new visualization/discovery platform that we can exploit in many ways. It could become one of our signature accomplishments. 5. Chao is working hard with Shanan Peters to develop DeepDive approaches to more automated ways of building the mineral evolution database. A limitation now is that we only have access to Elsevier archives. Adding GeoScienceWorld references, or even all of Georef if that's possible, would be a major advance. And I gather Shanan is close to a deal with Wiley, as well. Chao's project is on Cr, and Dan is working on Mn, so we should make sure to shift resources to those elements when we complete cobalt. Also, Nick [is that right; the new undergraduate whose email I need] expressed a lot of interest in ore metals. He might start work on silver, but I'm thinking it makes much more sense to tackle an element of interest to the Keck project: Paul, what do you think? Cu (probably too big)? Ni (a good choice)? 6. Please send the group photo to Mike to post on our expanding Keck website. I know there's a lot more, but I have to catch a plane to SF. -- Robert M.
