Clay and Howie demonstrate stratigraphy. Well, stra-cat-igraphy.
Melissa Boles shared this adorable picture of her kittehs Clay (orange) and Howie (black and white). She also provided the geological interpretation, which is that Clay represents an older sedimentary layer, probably an iron-rich rock (perhaps a sandstone) that has been oxidized, turning the rock an orange-red color. Howie, who is deposited above Clay, represents a younger sedimentary layer. Melissa suggests that Howie represents a black and white conglomerate with dark clasts and a light matrix. However, looking at the angular nature of the dark clasts, I wonder if Howie is actually a breccia-- or perhaps a glacial sedimentary rock such as till.
Thanks for sharing, Melissa! I hope that Clay and Howie are featyred again here on Geokittehs.
