Reconsideration on the C14 age dating period of the Bronze Age through the emergence time of the mandolin shaped bronze dagger
According to the C14 age dating, it is thought that the Bronze Age begun from the B.C. 15th century and the lute shaped bronze dagger was brought into the Korean Peninsula in 1100B.C. The upper limit of the Songgukri Assemblage is also thought in B.C. 10th century. Examining the mandolin shaped dagger in Liaoxi area and sacrificial vessel, set the emergence time of this dagger and consider when this dagger appeared in the middle part of the Korean Peninsula. And make comparison between this result and the C14 age dating of the Bronze Age. As a result, this dagger was brought into the Korean Peninsula in Gangshang phase B.C. 7th century. The Songgukri Assemblage begun after the B.C 6th century. There are 400~500 years apart in time comparing with the C14 age dating. Scientific result based on probability and statistics is not absolute unlike mathematical result. Even though scientific rule exists, there are many variables in the process of proving, so various solutions should be proposed to prove according to the times. The result by the C14 age dating method is just though as the best method in present time. According as how improves the method of analysis, the result should be also changed. Therefore, the C14 age dating must be applied to archaeological chronology with discretion.
