Paleoenviroment Reconstruction Using Geoarchaeological Methods

Introduction:

Reconstructed paleoenvironments are important because they allow archaeologists to give a setting for anthropological stories which allows for better understanding of what the people needed and what was available to them to meet these needs. This reconstruction is greatly aided by geoarchaeological methods such as X-Ray Diffraction, stratigraphy, particle size distribution, micro-material studies, micromorphology, Magnetic Susceptibility, and palynologic studies (Alam et al., 2008; Balbo et al. 2006; Boomer et al., 2007; Boyd, 2007; Bubenzer et al., 2007; Eitel et al., 2005; Ellwood et al., 2001; Farrand, 2001; Haynes, 2001; Hong et al., 2009, Hyoun Soo et al., 2007; Parker et al., 2006; Karkanas, 2001; Stanley et al., 2008; Tankersley et al., 2010). First, an explanation of these methods will be given, then three examples of how archaeologists use geoarchaeology to recreate paleoenviroments and why each recreation is important. The three example sites are Dongnimdong in South Korea, Awafi in the United Arab Emirates, and Polje Čepić in Croatia.

Methods:

X-Ray Diffraction is a method used to identify crystalline substances. When crystal structures are hit with X-Rays the amount of diffraction can be measured and used to produce a pattern. Every crystalline material has a unique pattern of which extensive databases have been made. These databases can then be used to identify unknown substances in a sample. Sourcing sediments using the presence and intensity of heavy minerals and approximating paleoclimates using clay components are both important uses of X-Ray Diffraction for reconstructing paleoenvironments geoarchaeologically (Alam et al., 2008; Farrand, 2001; Hong et al., 2009; Tankersley et al., 2010).

...ractices (Balbo et al., 2006). This site is similar to the Korean site in the way it helps archaeologists understand the changes man made to his environment when first developing agriculture. Understanding paleoenviroments is not only important for this reason but also because it allows for the natural state to be observed.

Conclusion:

Reconstructing paleoenviroments and the changes that have occurred in them is very important for archaeology as it shows the original state of nature that man evolved in, the changes we then made, and the processes that created the environment we now inhabit. Geoarchaeological methods are relatively simple, accurate ways of puzzling out the contingents of paleoenviroments. You cannot understand the cultures of the past without understanding the world of the past and these methods are the most apt to help archaeologists do so.
