What is BIF and what are the rock types contained within BIF?
Where and when was BIF deposited?What were the conditions responsible for BIF deposition?What organisms were largely responsible for the deposition?What was the chemical composition of the atmosphere and ocean like with respect oxygen and CO2 before BIF deposition? After BIF deposition?In what way were the ocean waters “stratified”?Where did all the silica and Iron come from?How could a little thing like blue-green algae change the composition of the atmosphere, oceans, cause global climate change such as ice ages, cause the deposition of Banded Iron Formation, and cause the deposition of huge amounts of limestone?
