“…Although quartz is rare in basaltic andesites, in these flows on the Jumento volcano the presence of large quartz crystals, considered as crustal xenocrysts (Arce et al, 2015), allowed the use of 10 Be dating. To our knowledge, the Jumento volcano is the second place worldwide where this method has been applied, the first being the Kula volcanic field (western Turkey) (Heineke et al, 2016); hence, 10 Be CRE dating can be useful to date Holocene volcanic rocks if the mineralogical composition allows it. In fact, crustal xenocrysts are common in the Sierra Chichinautzin (Meriggi et al, 2008;Arce et al, 2013) and 10 Be CRE ages could thus potentially be obtained on other volcanic edifices…”

In this study, horizontal temperature measurements along organized grids have been used to detect subaqueous hot springs. The study area, located in the southwest of Turkey and comprised of Köyceğiz Lake, Dalyan Channel and Fethiye-Göcek Bay, was scanned by measuring temperatures horizontally, 2-3 meters above the bottom of the lake or sea. After analyzing the temperature data along the grids, the locations with anomalous temperature values were detected, and divers headed here for further verification. Accordingly, among these anomalies, the divers confirmed seven of them as subaqueous hot springs. Three of these hot springs are located in the Köyceğiz Lake, three of them are located in the Dalyan Channel and one hot spring is located in the Fethiye-Göcek Bay. At the locations where temperature anomalies were detected, the divers collected samples directly from the subaqueous hot spring using a syringe-type sampler. We evaluated these water samples together with samples collected from hot and cold springs on land and from local rivers, lakes and the sea, with an aim to generate a conceptual hydrogeochemical model of the geothermal system in the study area. This model predicts that rainwater precipitating in the highlands percolates through fractures and faults into the deeper parts of the Earth's crust, here it is heated and ascends through the sea bottom via buried faults. Pervious carbonate nappes that are underlain and overlain by impervious rocks create a confined aquifer. The southern boundary of the Carbonate-Marmaris nappes is buried under alluvium and/or sea/lake water bodies and this phenomenon determines whether hot springs occur on land or subaqueous. The chemical and isotopic properties of the hot springs point to seawater mixing at deep levels. Thus, the mixing most probably occurs while the water is ascending through the faults and fractures. The gas geochemistry results reveal that the lowest mantle He contributions occur in the samples from Köycegiz Lake, whereas the highest ones are found in samples from the Dalaman plain. For the first time, we made use of the micro-XRF sediment core scanning (ITRAX Scanner) for

“…In this sense, dating lava flows over time scales covering the last centuries to the last millennia is important to test models that aim at establishing potential patterns of eruption recurrence and thus to improve the prediction of future eruptions. Moreover, some stratovolcanoes are ice-capped, and better understanding their glacio-volcanic evolution helps evaluating the hazards related to the interaction between ice and volcanic activity (i. e. large debris flows and floods) (Lescinsky and Fink, 2000;Conway et al, 2015;Heineke et al, 2016).…”

“…Late Holocene lava flows that are exposed at the surface are parti-cularly well suited for CRE dating, because their exposure history is simple and the original surface features are often well preserved al-lowing to reduce the impact of erosion and exhumation on the nuclide inventory (Espanon et al, 2014;Fenton and Niedermann, 2014;Kurz et al, 2014;Medynski et al, 2015;Heineke et al, 2016). Moreover, as lava flows are static surfaces, they are not affected by nuclide in-heritance from previous exposure (Dunai, 2010;Dunai et al, 2014).…”

The knowledge of the eruptive history of volcanic centers allows for improving the evaluation of the related risks and hazards in populated areas, but substantially depends on the ability of dating the lava flows. However, traditional methods such as U-Th/He, 40 Ar-39 Ar, 40 K-40 Ar and radiocarbon dating are not always suitable. Therefore, an alternative approach based on the combination of in situ-produced 36 Cl based cosmic ray exposure dating, lichenometry and dendrochronology was tested on two lava flows (called Lava flow "A" and "B") from Pico de Orizaba (Mexico), previously attributed to 16th and 17th century eruptions, respectively. The presented results show that both lava flows are significantly older than their assumed 16th and 17th century ages. Regarding lava flow "A", the measured in situ-produced 36 Cl concentrations lead to a mean age of 3.03 ± 0.70 ka, while dendrochronology and lichenometry yield minimum ages of 834 and 1130 years, respectively. Regarding lava flow "B", the measured in situproduced 36 Cl concentrations lead to a mean age of 1.45 ± 0.35 ka, whereas lichenometry gives a minimum age of ∼1000 years. Overall, this demonstrates that the combination of in situproduced 36 Cl based cosmic ray exposure dating, lichenometry and dendrochronology has a considerable potential for dating purposes on young deposits and landforms, in particular on lava flows at high elevation sites.
