10Be dating of river terraces of Santo Domingo river, on Southeastern flank of the Mérida Andes, Venezuela: Tectonic and climatic implications

Pleistocene Glaciations in the Northern Tropical Andes, South America (Venezuela, Colombia and Ecuador)

“…10 Ma) to present (Kohn et al, 1984;Pindell et al, 1998). Quaternary uplift ranges between ~0.7 and 5 mm/a (Audemard and Audemard, 2002;Wesnousky et al, 2012;Guzmán et al, 2013).…”

“…MIS 3 glacier advances have been recently proposed at different locations of the Mérida Andes, based on TCN- 10 Be dated moraine boulders (Angel, 2016). A glacier advance was dated at ~50 ka in the Pueblo Llano Valley at around 2500 m a.s.l.…”

“…Rull, 1998;Mahaney et al, 2001;Dirszowsky et al, 2005;Stansell et al, 2005;Mahaney et al, 2007;Carrillo et al, 2008;Kalm and Mahaney, 2011). However, more recently contributions based on Terrestrial Cosmogenic Nuclide dating (TCN), specifically 10 Be of moraine boulders and roches moutonnées are available (Wesnousky et al, 2012;Angel et al, 2013;Carcaillet et al, 2013;Guzmán, 2013;Angel, 2016;Angel et al, 2016).…”

“…It is noteworthy that the confidence in radiocarbon dating has improved considerably over the past years. It is also important to note that different scaling schemes and production rates to calculate surface exposure ages were used in the original publications for Terrestrial Cosmogenic Nuclide 10 Be (TCN-10 Be) (e.g. Wesnousky et al, 2012;Carcaillet et al, 2013;Angel, 2016).…”

“…Wesnousky et al, 2012;Carcaillet et al, 2013;Angel, 2016). Production rates for 10 Be in the tropical Andes have only recently become available (e.g. Kelly et al, 2013).…”
