Progradation of Atchafalaya Delta, one of the most dynamic geological events of the century, has produced a sizable new sand body on the Louisiana coast. Evolution of depositional environments in Atchafalaya Bay has been determined from analysis of sediment cores and bathymetric surveys. Use of X-ray radiography has made possible recognition of a number of subenvironments within major environments. Atchafalaya Delta exhibits all the sedimentary environments recorded in earlier Mississippi delta lobes. However, excellent stratigraphic control and current knowledge of the processes of deposition in Atchafalaya Bay make it possible to better link process-response in this than in other Mississippi subdeltas. In contrast to the modem Mississippi subdelta, the Atchafalaya should prograde more rapidly, form thinner sand bodies, and eventually cover a wider area, much like the Lafourche, St. Bernard, and Teche delta lobes. <...>

The Earth and Moon Developed at the Close Scenario?

You are beginning a study of geology—the science of Earth. Your goal is to learn how Earth works. Along the way, you will learn about the importance of geology to humans. You will consider the origin of essential resources and the forces that drive geologic processes that are hazardous to our lives and livelihoods. This text is not simply a collection of facts to memorize. It is an invitation to think about how scientists use creativity, diligence, and technology to arrive at the current body of knowledge about Earth <...>
