quaternary_lithology_lt100k_gt300k

This web map service shows the rock type (lithology) of geological units of the seafloor originated in the Quaternary period (i.e. 2,588 Ma from now until today). The data were compiled by BGR from the EMODnet geology partner organisations between 2009 and 2021. The scale varies between 20 000 and 2 500 000.本网络地图服务展示了形成于第四纪（Quaternary）时期的海底地质单元的岩石类型（岩性，lithology），其时间范围为距今2588百万年（Ma）至现今。本数据集由BGR于2009年至2021年间，从EMODnet地质合作伙伴组织汇编而成，地图比例尺介于1:20000至1:2500000之间。
