Archaeological and Geological Fieldwork in Kenya

在美国国家科学基金会的SBER仪器竞赛中，斯坦利·安布罗斯博士将购买一辆四轮驱动的丰田陆地巡洋车，以方便他在肯尼亚大裂谷的古人类田野调查。由于他研究的地点位于远离主干道的偏远地区，因此四轮驱动车辆是必要的。安布罗斯博士和他的同事们在南大裂谷的西肩找到了一个大约25乘50公里的区域，根据一个非常简短的检查，它被证明包含了20多个化石和考古遗址。以前的地质调查表明，该地区包含三个叠加的古湖泊。最古老的是晚中新世，最年轻的可能是上新世和更新世。暴露的地层剖面厚达185米，含有丰富的可追溯的火山灰。该地区丰富的化石和考古记录很可能在至少十年的时间里产生重要的新发现。安布罗斯博士启动了一项长期项目，以确定详细的地质序列，获得绝对日期，并重建随时间变化的环境。古生物学和考古遗址将被定位和挖掘，在此基础上，应该有可能在可能的600万年时间跨度内检查原始人的适应情况。这辆车也将被研究生使用，因此具有重要的教育功能。-一个v - +- ±@ + _ Uª▓能剧ª“+”ª▒0 Y + O $ H l + ¢ ╗ D h + y S u m m r I f n o r m t I o n ( ++++++++++++ % U ++++++++++++++++++++++++ ++++++++++++ r:\ wwuser \ template \ normal。点

Under the National Science Foundation's SBER Instrumentation competition, Dr. Stanley Ambrose will purchase a four wheel drive Toyota Landcruiser to facilitate his paleoanthropological fieldwork in the Kenyan Rift Valley. Because the sites he studies are located in isolated areas away from main roads a four wheel drive vehicle is necessary. Dr. Ambrose and his colleagues have located a ca. 25 x 50 km. region on the western shoulder of the southern Rift Valley which, on the basis of a very brief examination was shown to contain over 20 fossil and archaeological sites. Previous geological survey indicates that the region contains three superimposed paleolakes. The oldest is Late Miocene in age and the younger are probably Pliocene and Pleistocene. The exposed stratigraphic sections are up to 185 meters thick and contain abundant datable volcanic ashfalls. The area's rich fossil and archaeological record is likely to produce important new discoveries for at least a decade. Dr. Ambrose has initiated a long term project to determine the detailed geological sequence, obtain absolute dates and reconstruct changing environments over time. Paleontological and archaeological sites will be located and excavated and on this basis it should be possible to examine hominid adaptation over a possible 6 million year time span. The vehicle will also be used by graduate students and thus serve an important educational function. - À- v- +- ±@ + _ Ûª▓ ÑOh ª' +'ª▒0 Ý + Õ $ H l + ¢ ╗ D h + S u m m a r y I n f o r m a t i o n ( ++++++++++++ % Û ++++++++++++ ++++++++++++ ++++++++++++ R:\WWUSER\TEMPLATE\NORMAL.DOT
