Abstract

Abstract: The drill core ZK6 was scanned by a core scanner to obtain relative amounts of objective elements and magnetic susceptibility of sediment. Choose elements (involving K, Rb, Ba, Ti, and the like) and the characteristic curve of magnetic susceptibility as indexes, the feasibility of sedimentary facies discrimination was assessed based on the employment of a core scanner, which was achieved by comparing the scanning results with the layers where the samples were taken. The results suggest that both relative amounts of elements, such as K, Rb, Ba, Ti, Cr, Co, and V, and the characteristic curve of magnetic susceptibility are well in accordance with the three sedimentary cycles with respect to the layers.

Key words: core scanner, characteristic curve, sedimentary facies
