Autor: Raquel Alonso-Perez, James M.D. Day, D. Graham Pearson, Yan Luo, Manuel A. Palacios, Raju Sudhakar, Aaron Palke

Publikováno v: Artificial Intelligence in Geosciences, Vol 5, Iss , Pp 100085- (2024)

Emeralds – the green colored variety of beryl – occur as gem-quality specimens in over fifty deposits globally. While digital traceability methods for emerald have limitations, sample-based approaches offer robust alternatives, particularly for d

Recently Identified Mesoproterozoic Strata in South‐Central Idaho Document Late‐Stage Rifting of the Nuna Supercontinent in Western Laurentia

Autor: J. P. Lever, K. E. Sundell, D. M. Pearson, D.T. Brennan

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 25, Iss 6, Pp n/a-n/a (2024)

Abstract Sedimentary basins are valuable archives of tectonic processes involved in continental rifting. The northern Rocky Mountains preserve the Belt Supergroup, one of the most complete records of Mesoproterozoic strata on Earth; however, debate r

Widespread PREMA in the upper mantle indicated by low-degree basaltic melts

Autor: Ronghua Cai, Jingao Liu, D. Graham Pearson, Andrea Giuliani, Peter E. van Keken, Senan Oesch

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-10 (2023)

Abstract Studies of ocean island basalts have identified a Prevalent Mantle (PREMA) component as a fundamental feature of mantle geochemical arrays; however, its origin and distribution are highly controversial, including its potential link to plumes

Diamond preservation in the lithospheric mantle recorded by olivine in kimberlites

Autor: Andrea Giuliani, David Phillips, D. Graham Pearson, Soumendu Sarkar, Alex A. Müller, Yaakov Weiss, Robin Preston, Michael Seller, Zdislav Spetsius

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-9 (2023)

Abstract The diamond potential of kimberlites is difficult to assess due to several mantle and magmatic processes affecting diamond content. Traditionally, initial evaluations are based on the compositions of mantle-derived minerals (garnet, chromite
