EAE2522 Sediments and basins

Geologists study our Earth by digging through millions (and even billions) of years into the 'deep time' past. Older interpretations have been integrated with bold, new insights into a grand scenario of a dynamic planet 'on the move'. Continents break apart and reassemble; ocean floors open up and deepen into grand basins; volcanoes blow their tops; and even huge mountains systems rise up from originally quiet seas, a seemingly perpetual pageant of dynamic geologic processes. By studying and surveying global basins and their diverse infill of sediments and associated fossils, we can piece together the grand geologic puzzle through the ages. Fossil remains assist greatly in reconstructing ancient global continental connections, environments and climate, punctuated by global catastrophes to arrive at a picture of the evolution of life through time. This 'big picture science' is accomplished by diverse disciplines, including tectonics, sedimentology, stratigraphy, paleontology, geophysics, and field work, the latter of which is a significant skills set for the geologist. Ultimately, we endeavour to reconstruct our great earth jigsaw through the ages and in the modern age use the rock record of basins for global energy needs (i.e., water, oil, gas, and coal). In doing so, we enrich humanity by peering into unfamiliar and previously unknown ancient environments around the globe and by supplying important resources.
