Description
The major and trace elemental analyses of the Bennu samples OREX-800117-107 (SEIWG bulk aggregate), OREX-800107-101 (SOAWG bulk aggregate), OREX-800055-103 (angular lithology), OREX-803231-101 (hummocky lithology), and OREX-800023-113 (mottled lithology). All samples, excluding the hummocky lithology, show simialr compositions which are close to the average CI chondrite composition. The SOAWG bulk aggregate does however show contamination of the elements W, La, Ce, and Mo. As for the hummocky lithology, it shows a distinct elemental composition, likely due to its disticnt mineralogic differences.
