Geomorphology and spatial distribution of monogenetic volcanoes in the southern Puna Plateau (NW Argentina)

Morphological and multivariate statistical analysis of quaternary monogenetic vents in the Central Anatolian Volcanic Province (Turkey): Implications for the volcano-tectonic evolution

“…Many other important factors affect the morphological variations: (i) the absence of initial ideal cone/dome as in the case of many volcanic fields (e.g., Kervyn et al, 2012;Bemis and Ferencz, 2017;Haag et al, 2019); (ii) the age discrepancies among the cones/domes and hence different erosional/degradational processes that can also be linked to local climatological conditions (e.g., Fornaciai et al, 2012); (iii) the different eruption styles and facies distribution in scoria cones (e.g., Valentine and Gregg, 2008). Additionally, the average H /W ratio of all measured scoria cones is 0.08, which is within the limit of scoria cones formed in the extensional environments (Fornaciai et al, 2012).…”

“…Despite some successful attempts towards the estimation of relative ages based on the cone morphometry (e.g., Inbar et al, 2011;Haag et al, 2019), the use of traditional morphometric ratios (e.g., H /W ) mostly gives way to misleading interpretations due to the various internal and external effects that control the final morphology (e.g., Kereszturi et al, 2012;Kereszturi et al, 2013b). Therefore, here we only compared the formula and digital elevation model-based flank slopes of both scoria cones and lava domes with the available radiometric ages to check if there is any meaningful trend or not (Figs.…”

“…The spatial vent distribution is one of the best indications for the controlling mechanisms of the tectonic stress fields in volcanic fields (e.g., Takada, 1994;Le Corvec et al, 2013a;Muirhead et al, 2015;Haag et al, 2019). Therefore, the spatial distribution analysis of vents certainly provides new insights into the understanding of volcanological evolution and even risk assessments of the volcanic fields (e.g., Connor et al, 2000;Becerril et al, 2013;Mazzarini et al, 2013;Kósik et al, 2020).…”

Recent volcano-tectonic activity of the Ririba rift and the evolution of rifting in South Ethiopia

“…Classification of the different cinder cones is based on the different types proposed by Bemis & Ferencz (2017). The volcanic edifices were also qualitatively distinguished in different classes of maturity mainly based on the criteria defined by Haag et al (2019) derived from the critical analysis of the calculated morphometric data and recognition of textures and patterns on the high resolution (<5 m) Google Earth satellite images of the area (examples of different edifices attributed to the 4 different classes of maturity are shown in Fig. S2c of Supplementary material):…”

Lithium and Brine Geochemistry in the Salars of the Southern Puna, Andean Plateau of Argentina

“…Cenozoic andesitic and dacitic ignimbrites, associated with Miocene -Pliocene caldera complexes, largely cover the northern part of the Argentine Puna (particularly between 22°30' -23° S), whereas they are less abundant towards the south (de Silva, 1989;Caffe et al, 2002;Schnurr et al, 2007;Kay et al, 2010;Grosse et al, 2017Grosse et al, , 2018Montero López et al, 2015). Conversely, although mafic volcanism does occur in the North, the Southern Puna is characterized by a large number of Miocene-to-Quaternary mafic monogenic volcanoes (285 centers; Barcelos Haag et al, 2019), which are typically formed of Mg-rich basaltic andesites (Maro et al, 2017a). They are characterized by more primitive compositions than those in the north (Maro et al, 2017b).…”
