Radiometric correction effects in Landsat multi-date/multi-sensor change detection studies
(Taylor & Francis Ltd, 2006-12)
Radiometric corrections serve to remove the effects that alter the spectral characteristics of land features, except for actual changes in ground target, becoming mandatory in multi‐sensor, multi‐date studies. In this ...
A Late Eocene date for Late Triassic bird tracks
(Nature Publishing Group, 2013-03)
Bird-like tracks from northwest Argentina have been reported as being of Late Triassic age1. They were attributed to an unknown group of theropods showing some avian characters. However, we believe that these tracks are ...
New radiometric 40Ar–39Ar dates and faunistic analyses refine evolutionary dynamics of Neogene vertebrate assemblages in southern South America
(Nature, 2021-12)
The vertebrate fossil record of the Pampean Region of Argentina occupies an important place in South American vertebrate paleontology. An abundance of localities has long been the main basis for constructing the ...
Geochronological data from the Faxinal coal succession, southern Parana Basin, Brazil: A preliminary approach combining radiometric U-Pb dating and palynostratigraphy
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A radiometric zircon age of 285.4 +/- 8.6 Ma (IDTIMS U-Pb) is reported from a tonstein layer interbedded with coal seams in the Faxinal coalfield, Rio Grande do Sul, Brazil. Calibration of palynostratigraphic data with the ...
Evidence for maize (Zea mays) in the Late Archaic (3000-1800 B C ) in the Norte Chico region of Peru
(National Academy of Sciences, 2013)
For more than 40 y, there has been an active discussion over the presence and economic importance of maize (Zea mays) during the Late Archaic period (3000–1800 B.C.) in ancient Peru. The evidence for Late Archaic maize has ...
Pleistocene rock avalanche, damming, and secondary debris flow along the Cotahuasi river, Peru
(Elsevier, 2020-12)
Landslides are among the most frequent and dangerous mass removal processes around the globe. They can be triggered by different phenomena such as earthquakes, extraordinary rains, glacier outbursts, volcanic activity, ...
