They would all have fitted nicely into the field relationships that he had observed and his interpretation of them.The field relationships are generally broad, and a wide range of ‘dates’ can be interpreted as the time when the lava solidified.

He would say that the date represents the time when the volcanic lava solidified.

He assumes therefore that Sedimentary Rocks A are the same age as the other rocks in the region, which have already been dated by other geologists.

In the same way, by identifying fossils, he may have related Sedimentary Rocks B with some other rocks.

On his return, he sends his sample to the laboratory for dating, and after a few weeks receives the lab report.

Let us imagine that the date reported by the lab was 150.7 ± 2.8 million years.

As the researchers will report in tomorrow's issue of , they found that the Old Kingdom, which kicked off with Djoser's reign, began between 26 B.

by Tas Walker A geologist works out the relative age of a rock by carefully studying where the rock is found in the field.Egyptian records, such as the writings of the 3rd century B. On the other hand, they sometimes refer to astronomical events whose dates can be calculated today. But one recent paper by Spence, based on astronomical calculations, put it as much as 75 years later.Thus, scholars are confident that they are not wildly off the mark. For example, the first known pyramid, the Step Pyramid at Saqqara, was built as a tomb for King Djoser, and historians usually put the beginning of his reign between 26 B. Radiocarbon dating has been too imprecise to resolve these contradictions because in this period it usually has error ranges of between 100 and 200 years. The dating ranges are earlier than some historians had previously proposed.Just when did Egyptian pharaohs such as King Tut and Rameses II rule? Now a radiocarbon study concludes that much of the assumed chronology was right, though it corrects some controversial dates and may overturn a few pet theories."This is an extremely important piece of research that shows clearly that historical dating methods and radiocarbon dates are compatible for ancient Egypt," says Kate Spence, an archaeologist at the University of Cambridge in the United Kingdom. historian Manetho and inscriptions found at key sites such as Saqqara and Karnak, provide what are called "floating chronologies" because they are internally consistent but not anchored to absolute dates.His geological cross-section may look something like Figure 2.
