First paleomagnetic results of mid-to late Holocene sediments from Lake Issyk-Kul (Kyrgyzstan): Implications for paleosecular variation in central Asia

Gómez-Paccard, Miriam; Larrasoana, Juan C; Giralt, Santiago; Roberts, Andrew

Description

We present new paleomagnetic and rock magnetic data from mid and late Holocene sediments recovered in two gravity cores (C087 and C142a) from Lake Issyk-Kul (central Asia), for which independent radiocarbon-based age models are available. Our results indicate that sediments from core C087 are characterized by fine (pseudo single domain) magnetite grains and are reliable recorders of Holocene geomagnetic paleosecular variation (PSV) in central Asia, which is a region with poor data coverage....[Show more]
