Possible reasons for an extreme ecological disaster event in Zhoushan Archipelago during the period 5900–5600 yr BP
A 3.3-m-thick, 74.5-m-long ancient wood layer was discovered in Zhoushan Archipelago, East China Sea. The ancient woods were well preserved except for weak silicification of wood bark, and abundant amount of l...
