English: Bathymetric and geological map of LdM volcanic complex (based on Hildreth et al., 2010; Andersen et al., 2017; Singer et al., 2018). White, green, gray and red circles indicate coring sites, volcanic vents and sample locations for 40Ar,39Ar and 36Cl dating (Andersen et al., 2017) and El Piojo lake, respectively. The cores used to determine the reservoir effect correction are derived from site 3 (LEM13-3D-G: 14C age for the wood) and site 12 (LEM11-3A-G: 14C age for macrophytes). Gray circles showing eruptions (>25 kyr) composed principally of the ignimbrite of Cajones de Bobadilla (igcb; ∼950 kyr), rhyolite of Cerro Negro (rcn; ∼447 kyr), rhyodacite of Domo del Maule (rddm; ∼114 kyr), basalt of El Candado (bec; ∼63 kyr) and the andesite of Arroyo Los Mellicos (aam; ∼26 kyr). Eruptions (<25 kyr) include the rhyolite east of Presa Laguna del Maule (rep; 25.7 kyr), rhyolite of Loma de Los Espejos (rle; ∼19 kyr), rhyolite of Cari Launa (rcl; <3.3 kyr), rhyolite south of Laguna Cari Launa (rsl; 3.3±1.2 kyr), rhyolite of Arroyo de Sepúlveda (ras; 20–19 kyr), rhyolite of Cerro Barrancas (rcb; multiple flows 11.4–1.9 kyr), rhyolite of Colada Divisoria (rcd; 2.1±1.3 kyr), rhyolite of Colada Las Nieblas (rln; Late Holocene), rhyodacite of Arroyo de la Calle (rdac; ∼20±1.2 kyr), rhyodacite of Colada Dendriforme (rdcd; 8±0.8 kyr), rhyodacite of the northwest coulee (rdcn; 3.5±2.3 kyr), rhyodacite of Laguna Sin Puerto (rdsp; <3.5 kyr), rhyodacite west of Presa Laguna del Maule (rdop), andesite of Laguna Sin Puerto (asp; <3.5 kyr) and the younger andesite of the west peninsula (apj; 21±3.4 kyr). The age uncertainties are 2σ ^[1]
