应我国邀请,日本松田时彦教授等一行六人,于1989年6月14日至20日,在广东省进行学术交流活动。 这次学术活动包括学术报告和野外考察两部分。前者为期二天,后者为期四天。 东京都立大学贝冢爽平教授作了日本第四纪地质的研究报告。介绍了1987年出版的1:100万日本第四纪地质图的编制原则和方法。日本国内没有黄土,但第四纪火山灰广泛发育,是十分良好的构造标志层。通过测年学方法判别其形成时代,可对比研究许多新构造运动现象。
At the invitation of our country, Professor Masahiko Matsuda of Japan and his entourage attended the academic exchange activities in Guangdong Province from June 14 to June 20, 1989. The academic activities include academic reports and field trips in two parts. The former is two days, the latter for four days. Tokyo Metropolitan University Professor Naoki Kaizuka made quaternary geological research report. Introduced the principle and method of compiling 1: 1 million Japanese quaternary geological maps published in 1987. There is no loess in Japan, but Quaternary volcanic ash is widely developed and is a very good tectonic marker layer. Judging from the age of formation by the method of dating, many new tectonic movements can be compared.
