In the article titled “Dry CO2–CO Fluid as an Important Potential Deep Earth Solvent” [1], the authors mistakenly presented molar fractions for CO2 instead of CO in the subsection “Fluid in Albite Glass” of the Experimental Results section. Therefore, the second sentence in the sixth paragraph of the subsection, “These calculations showed XN2 = 0.043, 0.048, 0.051 in the fluids where XCO2 = 0.154, 0.164, 0.062 respectively”, should be corrected to “These calculations showed , 0.048, and 0.051 in the fluids where , 0.164, and 0.062, respectively”.
