What happened to a huge chunk of Earth’s history? – The Great Unconformity
There exists something in geology known as “The Great Unconformity”. This is the observation that there appears to be a gap that appears to consistently exist for specific geological layers around the planet. What exactly is this Great Unconformity? The first observation of this was made in 1869 by John Powell at the Grand Canyon. … Read more What happened to a huge chunk of Earth’s history? – The Great Unconformity
Two billion year old salt gives us insights into Oxygen
Roughly about 2.5 billion years ago the atmosphere of our planet dramatically changed – the quantity of oxygen rapidly increased and so we got breathable air. We have some new insights into it now, there is a new study. There exists a layer of salt deposits within a Russian geologic basin that was laid down during … Read more Two billion year old salt gives us insights into Oxygen
When did life first appear on earth?
We know that Earth is 4.54 ± 0.05 billion years old. There are no rocks from Earth that old because the process of plate tectonics has recycled anything of that era, so the estimate for this age is based upon the probable age of the Solar System. Basically the assumption is that all the solid bodies in the … Read more When did life first appear on earth?
