“…Until recently, most archaeological studies of spatial patterns of activity areas have focused on reconstructions of the location of activities based on the distribution of artifacts (Hardy Smith & Edwards, 2004;Hodder & Orton, 1979;Kuijt & Goodale, 2009;Simek, 1987;Whallon, 1973). This approach carries limitations in the form of both prior-and postdepositional taphonomic processes influencing the location of artifacts, and often portray problematic links between the location of artifacts and other contextual, functional, or chronological evidence (Manzanilla & Barba, 1990;Ullah, Duffy, & Banning, 2015). The need for geoarchaeological approaches for the study of spatial activity patterns at archaeological sites has driven several research projects in the past two decades seeking to test and apply various microscopic techniques to the study of activity areas, such as micromorphology (Banerjea, Bell, Matthews, & Brown, 2015;Milek & Roberts, 2013;Shillito & Ryan, 2013), geochemistry (Middleton & Price, 1996;Terry, Fabian, Fernández, Parnella, & Inomata, 2004;Vyncke, Degryse, Vassilieva, & Waelkens, 2011), phytolith and spherulite analyses (Cabanes, Mallol, Expósito, & Baena, 2010;Portillo, Kadowaki, Nishiaki, & Albert, 2014;Tsartsidou, Lev-Yadun, Efstratiou, & Weiner, 2009), and mineralogy (Shahack-Gross & Finkelstein, 2008).…”
