Utilizing a mega-regional dataset that includes over 20,000 km of on- and offshore 2D seismic traces and 12 wells, we illustrate three totally different phases of fault formation and basin evolution in the Caribbean arc-South American continent collisional zone.
Evidence thus far suggests that ferns and seed plants have existed since latest Devonian, that conifers first appeared close to the top of the Carboniferous, and that flowering vegetation appeared in vital numbers in the course of the Early Cretaceous.
Their lower concentrations during the Pleistocene Ice Ages point out that they contributed to the general cooling through the Pleistocene Epoch-a couple of 7.2°F (4°C) international average decrease in temperature. In these maps an try was made to re-create the distribution of land and sea not solely on the continents but also within the space of the modern oceans—by extrapolating from data from the encompassing land.
These ancient plants, animals, lands and seas have left traces as we speak that give us clues towards finding natural resources, akin to oil and gas. The basic concept behind the orbital theory is that decreases in summer season insolation in essential northern high latitudes allow permanent ice sheets to develop and increased summer season insolation causes the ice sheets to soften.
