This observation covers an outcrop of possible cyclic bedding within a crater in Arabia Terra.

"Cyclic bedding" refers to a pattern of layering caused by repeated fluctuations in the amount of available sediment that creates new rock layers. These fluctuations are caused by long-term changes in the region's climate, with periods on the order of millions, or possibly hundreds of millions of years. It's possible that even the wobble of the planet might be a contributing factor to cyclic bedding.

An image at HiRISE resolution can help evaluate the cyclicity of the beds, as well as test possible regional stratigraphic correlations, and perhaps, indications of a wetter past environment.

Made in Italy with a combination of silk and modal (Modal is a processed bio-based textile made from reconstituted cellulose from beech trees.) 

Our products are fair trade and made with eco-friendly ink.
