If the age of this unit were not so crucial to important associated hominid fossils, it probably would not have been dated at all because of the potential problems. The unfortunate part of the natural process of refinement of time scales is the appearance of circularity if people do not look at the source of the data carefully enough. Radiometric dating provides numerical values for the age of an appropriate rock, usually expressed in millions of years. So join for free today and start your search for like-minded senior singles. It can't float in mid-air, particularly if the material involved is sand, mud, or molten rock.
The data are determined by the rocks, not by preconceived notions about what will be found. However, there are some smaller differences. These types of distinctive events provide confirmation that the Earth's stratigraphy is genuinely successional on a global scale. Some of these events do exist.
There are innumerable independent tests that can identify and resolve inconsistencies in the data. The results are therefore highly consistent given the analytical uncertainties in any measurement. This reconstruction is tested and refined as new field information is collected, and can be and often is done completely independently of anything to do with other methods e. This observation led to attempts to explain the fossil succession by various mechanisms.
The methods work too well most of the time. The principle of original lateral extension - A rock unit continues laterally unless there is a structure or change to prevent its extension. Radiometric dating has simply made the estimates more precise, and extended it into rocks barren of fossils and other stratigraphic tools. Possibly this is an indication that the earthquake proposal is valid.
Every piece of data collected like this is an independent check of what has been previously studied. The name of these two cities have long been by-words in our language for wickedness. Estimates of the age of the Earth again returned to the prior methods.
