Cyclone-induced Net Sediment Transport Pathway on the Continental Shelf of Tropical Australia Inferred from Reef Talus Deposits

Tropical cyclones affect storm-dominated sediment transport processes that characterise Holocene shelf deposits in many shelf environments. In this paper, we describe the geomorphology of reef talus deposits found in the Gulf of Carpentaria and Arafura Sea, Australia,that we attribute to tropical cyclones. The orientation of these deposits is also indicative of a consistent, along-coast transport pathway.

热带气旋 (Tropical cyclones) 会调控受风暴主导的沉积物搬运过程，而该类过程正是诸多陆架环境中全新世陆架沉积的标志性特征。本文针对澳大利亚卡奔塔利亚湾与阿拉弗拉海海域发现的礁塌积物 (reef talus deposits) 的地貌特征展开系统描述，并将其成因归因为热带气旋。该类沉积的空间取向同样揭示了一条稳定的沿岸沉积物搬运通道。
