    Analysis of Yangtze River Delta at Mid-Holocene

    Map showing geological features, topography, and sediment distribution in Yangtze delta..

    Figure \(\PageIndex{1}\): The palaeo-shorelines, chenier ridges, and Neolithic cultural sites illustrate the delta progradation during the Holocene. (From Alberti et al. 2024. CC)
    1. The ancient shorelines for the last 8,000 years are marked on the map (Figure \(\PageIndex{1}\)). By how much had the sea level changed during this period of time?
    2. Explain why the Yangtze delta's size of land area had increased during the period of time of sea-level rise at the Holocene?
    3. What was the typical land elevation above the sea level in areas occupied human populations on the Yangtze delta?
    4. The neolithic (New Stone Age) cultures of Majiabang and Songze were predynastic Chinese cultures immediately preceding the Liangzhu culture. What were the approximate sizes of land area on the Yangtze delta and the dates of these two cultures?
    5. Locate the sites of the Liangzhu culture on this map.
