Fengjiahe Formation

The Fengjiahe Formation is a geological formation in China. It dates back to the Early Jurassic.[1] The formation is up to 1500 metres thick and consists of "purple-red mudstone and argillaceous siltstone interbedded with gray-green and yellow-green quartz sandstone and feldspathic quartz sandstone"[2]

gollark: As I said, my computer science class lacks any women despite them presumably having not been treated as incompetent at CS at some point. Unless it was some years ago, since CS is mandatory here when younger for bad reasons.
gollark: Excellent.
