Chemical and isotopic composition of gas, water, and solids from the 2019-2020 water lake in Halema’uma’u Crater, Kīlauea Volcano, Hawaii: X-Ray Diffraction (XRD) 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...研究人员于野外使用0.45微米滤膜（0.45 micron filter）对火山口湖湖水样品进行过滤。随后，在富溶质样品中形成了额外的沉淀物。
