Detailed Description

Figure 3. Mineral and organic matter components of SASP WY11 ALM dust. Untreated dust sample (A; Rtot; 32%). Mineral fraction (B; Rtot; 44%) and organic fraction (C; Rtot; 29%) after density-based separation. The color of the mineral fraction is due to the iron oxide minerals, goethite and hematite. Organic fraction contains some mineral matter due to incomplete separation; however, the dark organic matter is prominent.
