Chemical and isotopic composition of gas, water, and solids from the 2019-2020 water lake in Halema’uma’u Crater, Kīlauea Volcano, Hawaii: Chemical composition of solids filtered from water samples
Samples of the crater lake water were filtered in the field with a 0.45 micron filter. Subsequently, additional precipitates formed in the solute-rich samples (secondary precipitates). The solids that accumulated on the filters (both secondary and original precipitate) were digested by heating overnight in a sealed …
