Figure 3 Burns Formation: Contacts between stratigraphic units of the Burns formation as obtained by the Pancam at Burns cliff, Endurance crater. (a) Burns formation
at eastern end of Burns cliff. The three informal subdivisions (lower, middle, and upper units) of the formation are visible, as described in Fig. 4.
Because of its broad coverage, the scale varies significantly across area of image. This image is an approximate true-color composite mosaic
generated from images acquired on sol 278, sequence P2440, using Pancam’s 750, 530, and 430 nm filters. (b) Close-up of Wellington contact and
Burns lower unit strata. Note thick lamination of cross-bedding below contact, which contrasts with fine lamination above. Scale of cross-bedding
provided by bar in (a), and by visible concretions (small black dots) which are up to 3–5 mm in diameter. Grayscale bsuper-resolution imageQ using
Pancam’s 430 nm filter on sol 288. (c) Close-up of Burns middle unit/upper unit transition and Whatanga contact. Contact is characterized by an
upward gradation from light to dark tone in upper part of middle unit, followed by an abrupt shift to a much lighter tone which defines the contact.
