Arenites

Sandstone. Arenites. Quartz, felspathic and lithic. Some links to interesting examples...

1  3  4  5  Uluru Flinders Ranges Jamison Valley


Some more sandstone country renders. Tinkering...


The light in this render makes it look a little alien I'm thinking. Love how the dip correlates with the bedding planes. Thinly bedded sandstones like this may indicate a rhythmic depositional environment, perhaps lacustrine or marine in nature, the dip may indicate uplift due to compressional tectonic forces. Fun to speculate on the origins of a purely simulated landscape!
 

I like the light in this render although the bedding planes do not stand out as much. Low level clouds seem more appropriate in this render, indicating cool and humid air accumulating in valleys during the morning.

  1. Arenites (0-15% matrix) <-> Wackes (more than 15% matrix) <-> Mudrocks (mostly matrix or fine particles). The transition from no matrix to 100% matrix.
