The analysis and interpretation of pre-Brunhes (>.73 -.79 my) glacial landforms in the Nithi River Basin, on the eastern flank of Mount Kenya, provide evidence for the dynamics of early Quaternary ice. - (L'A.).
Conscious of the University of Kiel's motto of Pax optima a rerum, my aim in this fairly non technical addron is to overview the world's situation with regard to population, resources and food : where we are, how we got there and where we might
and alluvial deposits at Perrier Plateau and surroundings is presented correlatively with new K/Ar measurements. Precisions are given concerning faunas from Roca Neyra and Pardines (< 2.4 My), and from Champeix ( 0.8 My). These new data allow to point out
the fauna from Perrier-Etonaires at 2.6-2.5 My. This questions the lower limit of villafranchian stage.
are used to estimate mean erosion rates for the 3 periods (16 to 13 My, 13 o 8 My, and following 8 My). The landscape of the Huasco Valley is in a transient state, as indicated by well-preserved pediment surfaces in interfluves, valleys deeply incised
of the Quaternary is set at the top of the Olduvai event at 1.7 my. Four FADs, twelve LADs, two acme datums, and one ratio reversal datum occur above the base of the Quaternary at an average rate of about 1 per 100,000 yr. Five FADs and twelve LADs are recognized
in the 0.8 my interval between the top of the Olduvai event and the Gauss/Matuyama boundary at 2.5 my at an average incidence of about 1 per 50,000 yr.
obvious comparison is with the more general gamma distribution: although fitting is technically more awkward, methods publicised here allow estimation of parameters by maximum likelihood and computations for probably plots. The exponential my be a good
and by applying a new method, which calculates the amount of retreat from the width of beheaded valleys of known age. Rates of retreat range from 0.5 to 6.7 km/my. The results show that the rates of retreat are controlled by the thickness and resistance
