Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 259:301-322

South-central Chile is one of the most geodynamically active areas in the world, characterized by frequent volcanic eruptions and numerous earthquakes, which are both recorded in lake sediments. In Lago Icalma (39°S), long piston and short gravity c

Seismic stratigraphy of Lago Puyehue (Chilean Lake District): new views on its deglacial and Holocene evolution

Publikováno v: Journal of Paleolimnology. 39:163-177

Prior to the collection of a series of sediment cores, a high- and very-high-resolution reflection seismic survey was carried out on Lago Puyehue, Lake District, South-Central Chile. The data reveal a complex bathymetry and basin structure, with thre

Publikováno v: Journal of Paleolimnology. 39:179-195

This paper presents a multi-proxy climate record of an 11 m long core collected in Lago Puyehue (southern Chile, 40°S) and extending back to 18,000 cal yr BP. The multi-proxy analyses include sedimentology, mineralogy, grain size, geochemistry, loss

Late Quaternary climatic changes in southern Chile, as recorded in a diatom sequence of Lago Puyehue (40°40′ S)

Publikováno v: Journal of Paleolimnology. 39:219-235

A late Quaternary diatom stratigraphy of Lago Puyehue (40°40′ S, 72°28′ W) was examined in order to infer past limnological and climatic changes in the South-Chilean Lake District. The diatom assemblages were well preserved in a 1,122 cm long,

Giant earthquakes in South-Central Chile revealed by Holocene mass-wasting events in Lake Puyehue

Autor: F. Charlet, Jasper Moernaut, Robert Brümmer, Marc De Batist, Katrien Heirman, Roberto Urrutia, Mario Pino, Emmanuel Chapron

Publikováno v: Sedimentary Geology. 195:239-256

Very high resolution reflection seismic profiling (3.5 kHz) revealed nine Holocene mass-wasting events in Lake Puyehue (South-Central Chile). These events are made up of numerous coeval mass-wasting deposits and some homogenites, which are radiocarbo

Temporal evolution of sediment supply in Lago Puyehue (Southern Chile) during the last 600 yr and its climatic significance

Publikováno v: Quaternary Research. 64:163-175

Short-term climate changes in Southern Chile are investigated by a multi-proxy analysis of a 53-cm-long sedimentary sequence selected among eight short cores retrieved in Lago Puyehue (Chile, 40°S). This core contains a 600-yr-long undisturbed recor
