Event History of the Santiago Area (Chile): the Sedimentological Archive of Lago Lo Encañado
Event History of the Santiago area (Chile): the sedimentological archive of Lago Lo Encañado Thomas Pille 1 2 Acknowledgements Om te beginnen zou ik graag mijn promotor, Prof. Dr. Marc De Batist, bedanken voor dit interessante onderwerp en voor de tijd die u hierin gestoken hebt, voor de snelle verbeteringen en de veelbetekende tips en commentaren. Ook Maarten, mijn begeleider, verdient een welgemeende bedanking. Terwijl je het dit jaar zelf heel druk had (een doctoraat dat afgemaakt moest worden, je eerste kindje, een nieuw onderzoeksproject) vond je toch altijd de tijd om mij bij te staan. Vooral je enthousiasme en je doorzettingsvermogen zullen me bijblijven. Voor ieder klein vraagje waarmee ik kwam waren we een paar uur bezig, en vertrok ik niet enkel met een antwoord, maar ook met een hoofd vol extra ideeën. Philipp, obwohl ich ursprünglich nicht dein Thesis-Student war, hast du in der Abwesenheit von Maarten sehr viel Zeit in mein Project investiert. Was mir vor allem gefallen hat war das du bei einer Frage nicht einfach die Antwort gegeben hast, sondern auch versucht hast mir das Prinzip dahinter zu erklären. Vielen Dank für al deine Hilfe, und für eine schöne Reise nach Brest. Ich wünsche dir alles Gute bei deiner Doktorarbeit. I would also like to thank the rest of the RCMG staff, especially to Thomas, Mario, Willem, Oscar, Stan, Katrien and Koen. You were always there to help me if needed, or for a chat during a coffee break. The RCMG is a fantastic working environment. Mijn familie heeft er dit jaar (en eigenlijk doorheen mijn 5-jarige universitaire carrier) altijd voor mij gestaan. -

The Timing, Dynamics and Palaeoclimatic Significance of Ice Sheet Deglaciation in Central Patagonia, Southern South America
The timing, dynamics and palaeoclimatic significance of ice sheet deglaciation in central Patagonia, southern South America Jacob Martin Bendle Department of Geography Royal Holloway, University of London Thesis submitted for the degree of Doctor of Philosophy (PhD), Royal Holloway, University of London September, 2017 1 Declaration I, Jacob Martin Bendle, hereby declare that this thesis and the work presented in it are entirely my own unless otherwise stated. Chapters 3-7 of this thesis form a series of research papers, which are either published, accepted or prepared for publication. I am responsible for all data collection, analysis, and primary authorship of Chapters 3, 5, 6 and 7. For Chapter 4, I contributed datasets, and co-authored the paper, which was led by Thorndycraft. Detailed statements of contribution are given in Chapter 1 of this thesis, for each research paper. I wrote the introductory (Chapters 1 and 2), synthesis (Chapter 8) and concluding (Chapter 9) chapters of the thesis. Signed: ..................................................................................... Date:.............................. (Candidate) Signed: ..................................................................................... Date:.............................. (Supervisor) 2 Acknowledgements First and foremost, I am very grateful to my supervisors Varyl Thorndycraft, Adrian Palmer, and Ian Matthews, whose tireless support, guidance and, most of all, enthusiasm, have made this project great fun. Through their company in the field they have contributed greatly to this thesis, and provided much needed humour along the way. For always giving me the freedom to explore, but wisely guiding me when required, I am very thankful. I am indebted to my brother, Aaron Bendle, who helped me for five weeks as a field assistant in Patagonia, and who tirelessly, and without complaint, dug hundreds of sections – thank you for your hard work and great company. -

Impact of the 1960 Major Subduction Earthquake in Northern Patagonia (Chile, Argentina)

Forel and Department of Geology and Paleontology, University of Geneva, Geneva, Switzerland dInstituto de Geociencias, Universidad Austral de Chile, Valdivia, Chile eCentro Regional Universitario Bariloche, Universidad Nacional del Comahue, Bariloche, Argentina fPhysical Geography,Universite´ de Lie`ge, Lie`ge, Belgium Available online 7 July 2006 Abstract The recent sedimentation processes in four contrasting lacustrine and marine basins of Northern Patagonia are documented by high- resolution seismic reflection profiling and short cores at selected sites in deep lacustrine basins. The regional correlation of the cores is provided by the combination of 137Cs dating in lakes Puyehue (Chile) and Frı´as (Argentina), and by the identification of Cordon Caulle 1921–22 and 1960 tephras in lakes Puyehue and Nahuel Huapi (Argentina) and in their catchment areas. This event stratigraphy allows correlation of the formation of striking sedimentary events in these basins with the consequences of the May–June 1960 earthquakes and the induced Cordon Caulle eruption along the Liquin˜e-Ofqui Fault Zone (LOFZ) in the Andes. While this catastrophe induced a major hyperpycnal flood deposit of ca. 3 Â 106 m3 in the proximal basin of Lago Puyehue, it only triggered an unusual organic rich layer in the proximal basin of Lago Frı´as, as well as destructive waves and a large sub-aqueous slide in the distal basin of Lago Nahuel Huapi. -
