“…2) was found at 78-79 cm in this core, corresponding to an extensive time-parallel marker horizon across the LVF such as Lake Xiaolongwan (e.g. Mingram et al, 2004;Liu et al, 2009). This basaltic tephra layer came from the local volcanic eruption of LVF and its composition is distinct from recent eruptions of the Changbaishan volcano (Guo et al, 2005;Liu et al, 2009).…”

“…There are no felsic volcanic eruptions in the LVF during the Quaternary period (Fan et al, 1999;Guo et al, 2005;Liu et al, 2009) and thus this tephra layer could not be from LVF (Fig. 4 A).…”

“…This event was one of the largest explosive eruptions on Earth during the last 2000 years and is comparable in magnitude to the 1815 eruption of Tambora, Indonesia (Sigurdsson and Carey, 1989). In addition, the AD 460 estimated eruption by Varve-chronology for the Jinlongdingzi volcano in Longgang volcanic field of NE China was identified as the most recent explosive basaltic eruption (Liu et al, 2009). Both Tianchi and Jinlongdingzi volcanos located in the NE China, had a heavy impact on vegetation and climate in that area since the volcanoes erupted (Machida et al, 1990;Liu et al, 1998;Mingram et al, 2004;Guo et al, 2006;Stebich et al, 2007;Parplies et al, 2008;Jiang et al, 2008).…”

“…Jinlongdingzi Volcano is the youngest active cone. During the past 15000 years, Jinlongdingzi Volcano erupted several times and all have been confirmed as basaltic magma eruptions (Fan et al, 1999(Fan et al, , 2002Liu et al, 2009). The present regional topography of the Longgang Volcanic Field was shaped mainly in late Pliocene to early Pleistocene times, due to westward subduction of the West Pacific plate and associated volcanic activity (Liu, 1999).…”

Volatiles erupted from large-scale explosive volcanic activities have a significant impact on climate and environmental changes. As an important ecological factor, the occurrence of fire is affected by vegetation cover, and fire can feed back into both vegetation and climatic change. The causes of fire events are diverse; and can include volcanic eruptions. The amount of charcoal in sediment sequences is related to the frequency and intensity of fire, and hence under good preservation conditions fire history can be reconstructed from fossil charcoal abundance. Until now, little research on the role of fire has been carried out in northeastern China. In this study, through research on charcoal and tephra shards from Gushantun and Hanlongwan, Holocene vegetation change in relation to fire and volcanic events in Jilin, Northeastern China, was investigated. Where tephra shards are present in Gushantun it is associated with low level of both conifers and broadleaved trees, and is also associated with a pronounced charcoal peak. This suggests forest cover was greatly reduced from a fire caused by an eruption of the Tianchi volcano. We also detected one tephra layer in Hanlongwan, which also has the almost same depth with low level forest pollen values and one charcoal peak. This was caused probably by an eruption of the Jinlongdingzi volcano.

Seismic constraints on magma evolution beneath Mount Baekdu (Changbai) volcano from transdimensional Bayesian inversion of ambient noise data

The magmatic process of continental intraplate volcanism (CIV) is difficult to understand due to heterogeneous interactions with the crust and the lithospheric upper mantle. Mount Baekdu (Changbai) volcano (MBV) is one of the prominent CIVs in northeast Asia that has shown a complex history of eruptions and associated magmatic structures. In addition, the relationship between the crustal magmatic structures and upper mantle phenomena are enigmatic due to the lack of consistent seismic constraints for the lithospheric structure. To enhance comprehensive understanding of the MBV magma evolution, we image the lithospheric structure beneath the MBV and surrounding regions using ambient noise data and the following two approaches: (1) multiple measures of ambient noise dispersion are acquired through different methods and (2) a transdimensional Bayesian inversion method is utilized to obtain unbiased results in joint analysis of the multiple data sets. The estimated Earth structure shows a thick crust (~40 km) and a crustal anomaly with relatively high S wave velocity in the depth range 20–40 km. This type of structure extends to ~100 km north from the MBV and is accompanied by the shallow and rapid S wave velocity decrease beneath the mantle lid (~80 km). Through a comparison with previous P wave models, we interpret this structure as a consequence of compositional partitioning by mafic underplating and overlying cooled felsic layers as a result of fractional crystalization.
