"New research reveals connection between Earth’s atmospheric changes & mantle chemistry

... magmas formed in ancient subduction zones, where portions of Earth’s crust sink back into the mantle, from a pivotal moment in Earth’s history—the Great Oxidation Event (#GOE). ... which is estimated to have happened between 2.1 & 2.4 billion years ago, was a period of time when oxygen levels in Earth’s atmosphere increased rapidly & transformed life and environments on Earth."

Science mastodon please weigh-in: I recently saw a claim that only oxygenic photosynthesis produces gas as a by-product, BUT I thought that anoxygenic photosynthesis based on retinal vs chlorophyll produced CH4 - so is the 1st claim wrong or the 2nd? #GOE #stromatolite

Sending good vibes and prayers to all seminarians in the states gearing up for the #goe this week. Have fun and chill... you won't use any of that stuff once you are ordained! And they are not a good indicator of your worth as a person.
