摘要: Recent excavations carried out in several Bed I and II sites have shown that hominins at Olduvai Gorge used both bipo lar freehand knapping methods for quartz reduction. Due to the petrographic nature of its heterogeneous response fracture, identification bipolar any given site can be ambiguous controversial. This work aims overcome this problem by developing an experimental referential framework recognition characteristic features flakes produced through reduction Naibor Soit cores. The final goal is use a set variables related local obtained two independent controlled experiments, order statistically differentiate diagnostic technological traits best indicate on raw material type. Las recientes excavaciones que hemos llevado cabo en varios yacimientos localizados los Lechos y han puesto de manifiesto homininos la Garganta se sirvieron sendos metodos talla mano alzada para llevar sus procesos reduccion del cuarzo. Dada naturaleza petrografica cuarzo su heterogenea respuesta fracturacion, identificacion un yacimiento dado puede ser ambigua controvertida. El presente estudio pretende afrontar este problema con el desarrollo marco referencia reconocimiento rasgos diagnosticos las lascas producidas traves talla, respectivamente, nucleos procedentes Soit. objetivo trabajo es servirse conjunto relacionadas fractura producida por modelos alzada, obtenidos dos experimentos independientemente controlados, objeto diferenciar estadisticamente ras gos tecnologicos pueden indicar forma mas acertada presencia tipo mate ria prima.
