Is a Thin Surface Layer Representative<br />
Concept of a “split”<br />
– Grind up a rock, homogenize the bulk sample, and<br />
take a small sample for analysis.<br />
<strong>Asteroid</strong> surfaces layers as “splits”<br />
– Surface area of 100 km diameter spherical<br />
asteroid = 31,415 km 2 = 3.14 x 10 10 m 2<br />
– Volume of 100 µm (10 -4 m) surface layer<br />
= area x thickness = 3.14 x 10 10 m 2 x 10 -4 m<br />
= 3.14 x 10 6 m 3 ~ 3 million metric tons<br />
Thin asteroid surface layers sample very<br />
large masses of material!
