Why are surface characterizations<br />
important<br />
The surface material of a body is generally a<br />
mixture of all near-surface geologic units<br />
– In “disrupted-and-reaccreted” bodies, it samples<br />
all internal geologic units.<br />
Surface composition (Chemistry)<br />
– Element abundances<br />
– Element ratios<br />
– Isotopes<br />
Surface Mineralogy<br />
– Mineral types<br />
– Mineral Abundances and Compositions
