This method is used mainly for short-lived radioactive nuclides produced by cosmic ray spallation, such as °Be, A1, Si, C1, and Ar (Table 5-1). Because these nuclides have relatively short half-lives, if there was any initial amount of the nuclides at the beginning of Earth history, the initial amount would have completely decayed away. The small amount that can be found in... 

There have been roughly five periods in Earths history where much of the planet was covered in ice. Global climate cooled for millions of years. The sheets of ice at the north and south poles of the planets grew to cover the oceans. The amount of CO2 in the atmosphere dropped. These periods are widely known as ice ages. Atmospheric carbon dioxide dropped by about 25% during each major ice age. The drop in atmospheric carbon dioxide happened at the same time that global climate got colder. There just wasn t enough carbon dioxide to trap heat from the Sun and keep the planet s surface warm.

Much of the chemical, mineralogical, and isotopic data on which our ideas of the evolution of Earth s surface environment are based come from analysis of sedimentary carbonates. Unfortunately because of the increased susceptibility of the sedimentary carbonate mass to alteration and destruction by the processes of weathering, subduction, and metamorphism, much original information is lost from the rock record with increasing age of the carbonate mass. We are left with a biased record of the preserved sedimentary carbonate rock mass. The Precambrian Eon, which includes more than 85% of Earth history, contains only about 25% of the mass of sedimentary carbonates in existence ...
