Quaternary profile type map sheet 4-5 – 11-12 Ostend

This map gives an overview of the Quartarian profile types found on the map sheet. The map shows the sequence of most recent deposits. These deposits are eolic, fluviatiel, tidal deposits or slope deposits. The surfaces of the quarta map represent the areas where similar successions of specific quaternary layers (profile types) occur. The thickness of the various component layers of a profile type must, in particular, provide guidance on the additional isohypsen and isopacher cards and additional texts. The quarernary deposits in Flanders are lateral and vertical heterogeneous and vary widely in thickness.本地图概述了图幅内的第四纪（Quaternary）剖面类型。该地图展示了最新沉积层的发育序列，此类沉积涵盖风成、河流相、潮相及斜坡沉积四类。本第四纪地图的覆盖范围对应发育特定第四纪层序（即剖面类型）相似序列的区域。特定剖面类型的各组成层厚度，尤其可为附加等高线图、等厚线图及配套文本提供参考依据。佛兰德斯地区的第四纪沉积在横向与纵向上均表现出显著非均质性，且厚度差异悬殊。
