Chapter 15: Late Cretaceous–Pliocene Paleogeography of the Circum-Caribbean Region Based on Quantitative Plate Reconstruction and Georeferenced Databases

Alejandro Escalona, Sayyid Suhail Ahmad, Lisa Watson

Abstract

We present seven paleogeographic maps from the Late Cretaceous to Pliocene for the circum-Caribbean region. The maps represent a comprehensive integration of data (e.g., well, outcrop, seismic, maps, etc.) from our own study and published data. The interpretations were conducted interactively using mapped data and spatial databases (Watson and Escalona, 2021) alongside the construction of a quantitative plate model based on paleogeographic information systems (Escalona et al., 2021). The maps reproduce the variation of sedimentary-facies distribution though time. In particular, the wide coverage of the study area provides insights into the onshore and offshore timing and filling of basins, subsidence patterns, and development of paleodrainages from large catchment areas, such as the northern margin of South America, to smaller source of sediments, such as the Great Arc of the Caribbean and the Central American Arc. Paleogeographic maps also illustrate how the various fault systems conditioned the capture and redirection of sedimentation through time.
