Archaeological and Geological Fieldwork in Kenya

在国家科学基金会的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舰，以方便他在肯尼亚裂谷的古人类学实地考察。因为他研究的地点位于远离主要道路的孤立地区，所以四轮驱动车辆是必要的。安布罗斯医生和他的同事找到了一个。25 x 50公里。该地区位于东非大裂谷南部的西肩，根据一项非常简短的检查，该地区有20多个化石和考古遗址。以往的地质调查表明，该地区包含三个叠加的古湖泊。最古老的是晚中新世，较年轻的可能是上新世和更新世。出露地层剖面厚达185米，含有丰富的可定年火山灰。该地区丰富的化石和考古记录可能会产生至少十年的重要新发现。Ambrose博士发起了一个长期项目，以确定详细的地质序列，获得绝对日期并重建随着时间的推移而变化的环境。古生物学和考古学遗址将被定位和挖掘，在此基础上，应该有可能在可能的600万年时间跨度内研究原始人类的适应性。研究生也将使用这辆车，从而发挥重要的教育功能。 - - v- +- ±@ + _ 你好，我的天啊 Ý + Õ $ H L + ¢ ╗ D H + S um m m ary in for m m a t i o n ( ++++++++++++ % Û ++++++++++++ ++++++++++++ ++++++++++++ R:\WWUSER\TEMPLATE\NORMAL.DOT

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
