【摘要】 研究了香港海域16口钻井的岩心的沉积学和微体古生物学后,将它们划分为以下地层: （1）全新世海相沉积(最老的¹⁴C年龄为距今8080±130年); （2）最后冰期陆相沉积(¹⁴C年龄为距今8520±270—<30000年); （3）含有红树植物孢粉的最后间冰期海相沉积(¹⁴C年龄距今30560±580—36230±₆80年)。 （4）中玉木冰期的陆相沉积; （5）?含放射虫的第二最后间冰期海相沉积; （6）?前第二最后间冰期的陆相沉积。 在最后间冰期时期,海平面至少低于基准面（基准面:大约低于平均海面115米）9米。微体古生物的证据表明,当时的年平均温度高于现今。更多还原

【Abstract】 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.更多还原
