Creamer, C.A., Foster, A.L., Lawrence, C.R., McFarland, J.W., Schulz, M.S., and Waldrop, M.P., 2019, Batch sorption data, respired CO2, extractable DOC, and Raman spectra collected from an incubation with microbial necromass on feldspar or amorphous aluminum hydroxide: U.S. Geological Survey data release, https://doi.org/10.5066/P9IHA9YN.

The purpose of this experiment was to determine the role of mineralogy and microbial processing on the retention of microbial C on mineral surfaces. These data were collected to test whether mineralogy influenced the pathway of necromass association with minerals. Specifically, we tested whether microbial necromass directly sorbed to mineral surfaces or was consumed by live microorganisms prior to mineral association. Examples of appropriate uses of these data would be: inclusion of the mass balance or sorption data in a meta-analysis, inclusion of this data in a model for sorption or microbial assimilation or C substrates on different minerals, or analysis of the Raman spectra for comparison to other data on changes in mineral-associated chemistry through time or on different minerals.
