Silt Blocks are soils that are very similar to 沙塊s that start appearing from the 洞穴 地層. It is affected by gravity and will deal damage to any player or mob they fall on. Unlike sand, It can stop 神聖之地, 猩紅之地, and 腐化之地 from spreading. It looks similar to 灰燼塊s, but is a lighter color.
- 首次血肉牆被打敗之時，即所謂"光明與黑暗之魂"被釋放出來時,被劃為新形成的腐化、猩紅和神聖生物群系中的泥沙塊會被分別轉換成黑檀沙或猩紅沙還有珍珠沙，就像普通的沙子。After this initial conversion however, Silt Blocks are not affected by the spread of Corruption and Hallow.
- Just like 雪泥 and other forms of sand, it disappears when it falls on a rail track.
- Silt can be used in the same way as 沙 to fill lava pits. It can also be used in creating traps, since it causes damage to whatever it falls onto.
