Introduction: Reconstructed paleoenvironments are important because they allow archaeologists to provide a setting for anthropological stories that allows for a better understanding of what people needed and what that was available to them to meet these needs. This reconstruction is greatly aided by geoarchaeological methods such as X-ray diffraction, stratigraphy, grain size distribution, micromaterial studies, micromorphology, magnetic susceptibility and palynological studies (Alam et al., 2008; Balbo et al. 2006 ; Boomer et al., 2007; Bubenzer et al., 2007; Ellwood et al., 2007; Parker et al., 2006; geoarchaeology for recreating paleoenvironments 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 substances crystalline structures When crystalline structures are hit by X-rays, the amount of diffraction can be measured and used to produce a pattern. Each crystalline material has a unique pattern of which large databases have been created. These databases can then be used to identify unknown substances in a sample. Sediment sourcing using the presence and intensity of heavy minerals and approximating paleoclimates using clay components are both important uses of X-ray diffraction to geoarchaeologically reconstruct paleoenvironments (Alam et al., 2008; Farrand, 2001; Hong et al., 2009; Tankersley et al., 2010).S......half article......practices (Balbo et al., 2006). This site is similar to the Korean site in the way it helps archaeologists understand the changes humans made to their environment when they first developed agriculture. Understanding paleoenvironments is not only important for this reason but also because it allows us to observe their natural state. Conclusion: Reconstructing paleoenvironments and the changes that occurred in them is very important for archeology because it shows the original state of nature in which man evolved. in, the changes we then made and the processes that created the environment we live in now. Geoarchaeological methods are relatively simple and accurate methods for disconcerting the contingents of paleoenvironments. It is not possible to understand past cultures without understanding the world of the past, and these methods are best suited to help archaeologists do so.
