Rare, erosional turret bedforms are described in a coastal foredune environment. These ephemeral structures are formed as a result of moist columns of sand being sculpted by aeolian action of saltating particles. Mature formation of these features appears to be facilitated by the action of an advancing foredune ridge, first preserving and then isolating the turrets for further enhanced erosion within a dune environment. It is envisaged that these structures may be preserved in dune stratigraphy.

沿海前陆群中短暂的床状炮塔的形成

在海岸前缘环境中描述了罕见的侵蚀性炮塔床形态。这些短暂的结构是由潮湿的沙柱在盐粒的风积作用下雕刻而成的。这些特征的成熟形成似乎是通过前进的前沙脊的作用促进的，首先保留然后隔离炮塔以进一步增强沙丘环境中的侵蚀。预计这些结构可能会保留在沙丘地层中。
