DOI: 10.1016/j.gca.2019.07.049
Abstract: Abstract We report [Li] and δ7Li values for a well-characterized suite of 52 geographically (165–184°W), compositionally (SiO2 = 46–70 wt.%), and temporally (0–38 Ma) diverse lavas and intrusive samples. The δ7Li in these rocks range from −0.7‰ to… read more here.

DOI: 10.1016/j.gca.2020.12.006
Abstract: Abstract Clay weathering in shales is an important component of the global Li budget because Li is mobilized from Li-rich clay minerals and shale represents about one quarter of the exposed rocks on Earth. We… read more here.

DOI: 10.1016/j.oregeorev.2021.104328
Abstract: Abstract Porphyry Cu deposits can be classified at the global scale as oceanic subduction- and continental collision-types based on their tectonomagmatic settings. In order to further characterize the possible differences in the geochemical and isotopic… read more here.

DOI: 10.2475/02.2020.03
Abstract: In this study, we present new data on the δ7Li values and Li/(Ca+Mg) ratios of carbonate cores from the Great Bahama Bank (Clino, Unda), a deep water core off of the bank top (ODP Leg… read more here.
