Dear Jeong et al.,

I think the manuscript is ready for publication after a few technical corrections.

Please add the year of publication for Shao et al., 2008 and Conny, 2013 in the references list.

Please change the sentence (page 4, line 18) "The identification criteria for minerals are summarized in Supplement Information."
to
"The identification criteria for minerals are summarized in the Supplement."

Please Change the sentence (page 6, line 30) "Although the third dimension
could not be measured, the area% of iron (hydr)oxide grains approximates volume% because tiny iron (hydr)oxide grains had been homogeneously distributed through the dust particle (Vepraskas and Wilson, 2008)."
to
"Although the third dimension could not be measured, the measured area of iron (hydr)oxide grains approximates their total volume because the relativly small iron (hydr)oxide grains were homogeneously distributed throughout the dust particles (Vepraskas and Wilson, 2008)."

Best regards,
Harald Saathoff
