Progress In Optical Dating Of Guano-Rich Sediments Associated With The Deep Skull, West Mouth Of The Great Cave Of Niah, Sarawak, Borneo, Mark Stephens, Richard Roberts, O Lian, Hiroyuki Yoshida Mar 2013

Progress In Optical Dating Of Guano-Rich Sediments Associated With The Deep Skull, West Mouth Of The Great Cave Of Niah, Sarawak, Borneo, Mark Stephens, Richard Roberts, O Lian, Hiroyuki Yoshida

Richard G Roberts

The West Mouth of the Great Cave of Niah is one of the major archaeological sites in Southeast Asia; the radiocarbon chronology of this site currently places the earliest presence of Homo sapiens (a Deep Skull find) in Southeast Asia at about 45 ka BP. An optical dating programme using sand-sized quartz was initiated in the West Mouth to complement the radiocarbon chronology. This paper reports on the progress in dating a key sample (sample 376r) that was taken from deposits containing the Deep Skull. A somewhat novel procedure was developed to separate and clean quartz grains from the unusual …

F-Region East-Westdrifts At Jicamarca, Bela G. Fejer, D. T. Farley, C. A. Gonzales, R. F. Woodman, C. Calderson Jan 1981

F-Region East-Westdrifts At Jicamarca, Bela G. Fejer, D. T. Farley, C. A. Gonzales, R. F. Woodman, C. Calderson

Bela G. Fejer

F region east-west drifts have been measured at Jicamarca for almost 10 years, using incoherent scatter. The drifts are westward during the day and eastward at night. The daytime drift velocities are about 50 m/s and change very little with season or solar cycle. The evening reversal occurs at about 1600 local time throughout the solar cycle. The maximum nighttime eastward drifts are about 105 and 130 m/s during solar minimum and maximum, respectively. The daytime and nighttime drifts show very litle variation with magnetic activity. These Jicamarca incoherent scatter results (especially the reversal times) differ appreciably from results obtained …
