“…3700 to 4300 yr BP, which are consistent with radiocarbon data (Cheong et al, 2006). Recently a quartz OSL age estimate of 5.1 AE 0.3 ka was reported for the Hamori Formation (Cheong et al, 2007). Cheong et al (2007) also reported a quartz OSL age of 7.0 AE 0.3 ka from the Songaksan Tuff, underlying the Hamori Formation.…”

“…Recently a quartz OSL age estimate of 5.1 AE 0.3 ka was reported for the Hamori Formation (Cheong et al, 2007). Cheong et al (2007) also reported a quartz OSL age of 7.0 AE 0.3 ka from the Songaksan Tuff, underlying the Hamori Formation. Therefore, it is reasonable to assume that the Hamori Formation is of mid-Holocene age with a maximum age of about 7.0 ka, and the footprint-bearing strata should not be correlated with the Hamori Formation, but with the unnamed strata at the west coast of Mt.…”

Terra Nova, 23, 70–75, 2011 Abstract Continuous pyroclastic successions from monogenetic volcanoes in the Jeju Island Volcanic Field (Korea) were targeted for detailed geochemical investigations of juvenile ejecta to show that multiple distinct magma pulses may be erupted during a single monogenetic eruption. Deeply derived, and possibly multiply sourced, evolving magma pulses may erupt sequentially from the same vent and form generally uninterrupted depositional sequences with continuous chemical trends. Alternatively, pulses can rise independently, resulting in breccia horizons and truncation surfaces in depositional sequences and in stepped and mixed chemical trends. We infer that uninterrupted eruptions result from clear plumbing systems in which a single large dyke system feeds an eruption and where differently sourced magmas are erupted independently. Congested plumbing systems consisting of dyke complexes give rise to vent shifts, asymmetrical eruptive centres and composite depositional sequences. Integration of chemical variation and eruptive dynamics provides a powerful means of understanding monogenetic volcanoes.

“…Cheong et al . () argue that the light conditions in pyroclastic surges and ash plume are favourable for complete optical resetting of xenolithic quartz grains due to the only slightly increased optical density compared to the atmosphere. Furthermore, it is supposed that those quartz grains fall back in the volcanic vent multiple times before finally being ejected, thus elongating the potential time for bleaching of the OSL signal.…”

In Quaternary studies, tephras are widely used as marker horizons to correlate geological deposits. Therefore, accurate and precise dating is crucial. Among radiometric dating techniques, luminescence dating has the potential to date tephra directly using glass shards, volcanic minerals that formed during the eruption or mineral fragments that originate from the shattered country rock. Moreover, sediments that frame the tephra can be dated to attain an indirect age bracket. A review of numerous luminescence dating studies highlights the method's potential and challenges. While reliable direct dating of volcanic quartz and feldspar as a component in tephra is still methodically difficult mainly due to thermal and athermal signal instability, red thermoluminescence of volcanic quartz and the far-red emission of volcanic feldspar have been used successfully. Furthermore, the dating of xenolithic quartz within tephra shows great potential. Numerous studies date tephra successfully indirectly. Dating surrounding sediments is generally straightforward as long as samples are not taken too close to the tephra horizons. Here, issues arise from the occurrence of glass shards within the sediments or unreliable determination of dose rates. This includes relocation of radioelements, mixing of tephra into the sediment and disregarding different dose rates of adjacent material.
