Integration of regional stratigraphic relationships with data on sediment accumulation,
provenance, paleodrainage, and deformation timing enables a reconstruction of Mesozoic …

There is a considerable controversy about whether western Amazonia was ever covered by
marine waters during the Miocene [23 to 5 Ma (million years ago)]. We investigated the …

An appraisal of Paleogene floral and land mammal faunal dynamics in South America
suggests that both biotic elements responded at rate and extent generally comparable to …

Abstract The Northern Andes of Colombia is a key locality for understanding tectonic
inversion of symmetric rifts. A review of available data on structural geometry and …

Key Points We evaluate the Miocene tectonic evolution of the northwestern Andes of
Colombia through a multitechnical approach Ongoing exhumation and deposition of middle …

Miocene strike‐slip tectonics was responsible for creating and closing short‐lived (ca. 6 Ma)
passages and the emergence of isolated topography in the Northern Andes. These …

Unconformities in foreland basins may be generated by tectonic processes that operate in
the basin, the adjacent fold–thrust belt or the broader convergent margin. Foreland basin …

Detrital zircon U-Pb geochronology is widely used in reconstructing sedimentary
provenance, sediment dispersal pathways, and tectonic histories. These applications …

ABSTRACT Uplift of the Eastern Cordillera in the northern Andes has been linked to
orographic climate change and genesis of South America's largest river systems. The timing …

New biostratigraphic zonations, core descriptions, sandstone petrography, facies analysis,
and seismic information are compared with published detrital and bedrock geo-and …
