Monday Geology Picture: Ancient Egyptian Stone Jars
Posted by Evelyn Mervine
For this week’s “Monday Geology Picture” I thought that I would share another picture that I took during my recent visit to The British Museum. This week’s picture shows two beautiful ancient Egyptian stone jars. The jar on the left is made out of limestone breccia while the jar on the right is made out of andesite porphyry.
Here’s the museum sign about the two jars:
I guess limestone is Paleogene from west of the Nile, porphyry is ~800 Ma Dokhan from east. “Porphyry” is Latin for purple. This article provides more info about purple variant “Imperial Porphyry”: http://www.saudiaramcoworld.com/issue/199806/via.porphyrites.htm
whoops! 600 Ma Dokhan
