SEM image showing one example of the size and occurrence of iron oxide
Detailed Description
Figure 4. SEM image showing one example of the size and occurrence of iron oxide minerals in dust. This image shows a quartz grain coated with illitic and smectitic clays that was deposited at SASP during the D6 event in WY13 (4/8/2013). Bright spots are nanometer-sized iron oxide and titanium oxide domains. This type of mineral particle is common in dust deposited to SASP.
