Abstract

Sedimentological and micropalaeontological investigations on sixteen boreholes in Hong Kong waters reveal the following stratigraphy: -
(1) Holocene marine deposits (oldest ¹⁴c date 8,080±130 years B.P.).
(2) Last glacial terrestrial deposits (¹⁴c ages between 8,520±270 and less than 30,000 years B.P.).
(3) Last interstadial marine deposits with mangrove pollen and spores (¹⁴c ages between 30,560±580 and 36,230±680 years B.P.).
(4) Terrestrial deposits of Middle würm age.
(5) ? Second last interstadial marine deposits with radiolaria.
(6) ? Pre-last interglacial terrestrial deposits.
Sea-levels during the last interstadial reached at least -9 metres below Principal Datum (P.D. which is about 1.15 metres below mean sea level) and the microfossil evidence suggests annual mean temperatures higher than present at this time. Copyright © 1988 the University of Hong Kong.
