An inventory of large (> 0.5 km3) rockslides has been developed for the Chilean sector of the southern central Andes (32-34� S) through field mapping, aerial photo interpretation and satellite image analysis along a swath 200 km long and 75 km wide that comprises the central and western Cordillera Principal. Previous work has indicated two main controls for the ...

We present a structural analysis of strongly deformed Cenozoic volcanic rocks of the western Principal Cordillera between 34�15'S and 34�30'S. Deformation has been related to the inversion of the Abanico Basin occurred between 22 and 16 Ma. The structural array is characterized by a syncline with a very steep western limb and a rather flat slightly folded axial zone. On ...
Extensional basin development (Middle?-Late Eocene to Early Miocene), basin inversion and deformation of the basin fill (Early to Late Miocene) and rapid, high magnitude surface uplift (Late Miocene to Recent) characterize the Cenozoic tectonic evolution of the central Chilean Principal Cordillera, between 33� and 36�S. Extension (Abanico Basin) was associated with ...
The ongoing Andean orogeny is generally believed to have started in Miocene time. However, sedimentological studies of a Cenozoic clastic section in the northwestern foothills of the Venezuelan Andes (Rio Chama) yield two lines of evidence that uplift was already underway in the Oligocene. (1) Thick Oligocene shales (Leon Formation; 300m) are dark gray and ...

This paper examines the transnational migratory process and identity formation of a Japanese astronomer, Mutsumi Ishitkuta (born 1930). He moved to Peru in 1957 to build a solar observatory in the Andes Mountains, and settled there to develop a foundation for basic sciences in Peru. Through life story interviews, I explore the transnational migratory ...

This paper describes the development and status of the Cornell University Andes Project which began in the 1970's as a result of earthquake studies. Such mountain belts are of considerable importance because they are the source of the world's hydrocarbon and mineral resources. The thrust of the research is to understand the formation and ...
This activity compares different kinds of candy to the different types of rocks based on direct observation. Students are asked to make observations about candy samples and how they are formed. The formation of candy and the formation of rocks have many similarities; for instance, Andes Mints show definite layers and it can be inferred ...

For almost two centuries, understanding of the South American Cenozoic terrestrial biota was derived largely from the extensive but gap-riddled record from Patagonia and nearby lowland, high-latitude sites. But discoveries and analyses of Andean and tropical fossil mammal assemblages have increased substantially in recent years, and integrating these new paleontological data with those typically ...
This paper completes a three-part series on the formulation of 3-node, 9-dof membrane triangles with corner drilling freedoms based on parametrized variational principles. The first four sections cover element implementation details including determination of optimal parameters and treatment of distributed loads. Then three elements of this type, labeled ALL, FF and EFF-ANDES, ...
The petrotectonic characterization of accreted mafic remnants within the northern Andes and the Caribbean yield major insights on the growth and evolution of oceanic plates, as well as in the identification of the role of terrane accretion within the northern Andes orogeny. Within the northern termination of the Andes, in northern ...
Vertical variations in facies and sedimentary environments in an outcrop of the La Luna Formation in the Venezuela Andes were evaluated with an integrated study of sedimentology, micropaleontology, palynology, visual kerogen, organic geochemistry and field geology. Up to now, the La Luna Formation, main hydrocarbon source rock in the ...

In this paper, the quality of a reconstruction of daily snow frequency in the central Andes is evaluated by studying the atmospheric patterns related to anomalies in the reconstructed series. The origin of precipitation anomalies in this part of the world is relatively well known and is has been related to the El Niño/Southern Oscillation cycle through the Pacific ...
Idealized coupled ocean-atmosphere model experiments indicate that the mechanical effect of the Andes mountains on the atmospheric flow and local air-sea interactions are enough to modify a zonally and equatorially symmetric distribution of tropical sea surface temperature (SST) and rainfall to become qualitatively similar to the observed in the Pacific. The main mechanism ...
The uplift of the Andes was a major factor for plant diversification in South America and had significant effects on the climatic patterns at the continental scale. It was crucial for the formation of the arid environments in south-eastern and western South America. However, both the timing of the major stages of the Andean uplift and the onset of aridity ...

Four surface sections from the Venzuelan Andes were chosen for this study. The results show interesting trends for exploration of the Andean Belt. In the Eastern Andes (Trujillo), sections San Lazaro and Chejende yield thick, post-mature, highly tectonically disturbed La Luna Formation. San Lazaro section has a fault contact showing La ...
The Merida Andes exhibit the most complex tectonics in western Venezuela. By studying the different ages and regional distribution of rocks, we can describe some tectonic features which are of interest to oil exploration in this area. Vertical basement movements accompanied extensional tectonics from pre-Cambrian until Eocene times. For this time interval, we reconstructed ...
