Abstract
研究了香港海域16口鑽井的岩心的沉積學和微體古生物學後,將它們劃分為以下地層:
(1)全新世海相沉積(最老的¹⁴C年齡為距今8080±130年);
(2)最後冰期陸相沉積(¹⁴C年齡為距今8520±270—<30000年);
(3)含有紅樹植物孢粉的最後間冰期海相沉積(¹⁴C年齡距今30560±580—36230±680年)。
(4)中玉木冰期的陸相沉積;
(5)?含放射蟲的第二最後間冰期海相沉積;
(6)?前第二最後間冰期的陸相沉積。
在最後間冰期時期,海平面至少低於基準面(基準面:大約低於平均海面115米)9米。微體古生物的證據表明,當時的年平均溫度高於現今。
Sedimentological and micropalaeontological investigations on sixteen boreholes in Hong Kong waters reveal the following stratigraphy:
( 1 ) Holocene marine deposits (oldest 14C data 8080 ± 130 years B .P.).
( 2 ) Last glacial terrestrial deposits (14C ages between 8520±270 and less than 30000 years B.P. ).
( 3 ) Last interstadial marine deposits with mangrove pollen and spores (14C ages between 30560±580 and 36230±680 years B.P. ).
( 4 ) Terrestrial dePosits of Middle wurm ege.
( 5 ) ? Second last interstadial marine deposits with radiolaria.
( 6 ) ? Pre-second 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 廣東省地震局.
