How accurate carbon dating

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology, and even biomedicine.Back in the 1940s, the American chemist Willard Libby used this fact to determine the ages of organisms long dead.

The findings, based on soil samples taken from under a seven-meter thick walled tower, shave nearly a thousand years from previous archaeological dating of the structure, which placed it c.Based on pottery and architectural signifiers, the heavily fortified structure — and the rest of the Spring Citadel protecting Jerusalem’s precious water source — were dated to Canaanite construction (Middle Bronze II period).In addition to protecting the Gihon Spring, the massive fortification served as a sort of security barrier and permitted one entrance to the spring — “from the west only, from within the city,” according to the City of David website.“This is the largest fortress found in all of Israel to date between the Canaanite cities…and it seems that it is essentially the largest fortress found in Israel until the days of King Herod,” states the website.

However, new findings by an interdisciplinary cooperative team of Israel Antiquities Authority archaeologists and Weizmann Institute scientists place the construction of the tower during the second half of the Iron Age — smack dab in the middle of the Israelite period, and much closer to the days of Herod than earlier suspected.
