Strataday Saturday 002
Any thoughts?!
Scroll down for interpretation.
Update for Strataday Saturday 001. The dunes of White Sands, SE New Mexico, the largest gypsum dune field in the world. Wind is blown generally in an ENE direction. Dune types range from domal, transverse ridge, barchanoid ridge, barchan, and parabolic. For more examples of geological postings and musings, please visit https://applied-geoscience.com/wsag-blog/.

Strataday Saturday 002 Interpretation
Small-Scale Carbonate Buildup
The Strataday Saturday 002 example is of a small-scale carbonate buildup with some photoshop color manipulation. Figure 2 shows the original photograph along with the color-manipulated image. Individual smaller-scale buildups comprise the larger buildup. Steep dips on the flank are indicated by the closely- spaced bedding patterns, along with a couple of prominent faults. When I first photographed this, I kept a mental note to look for a seismic-scale example (Figure 3) that I later found on the Virtual Seismic Atlas (unfortunately, the site is no longer active but is available on the internet archive repository).
