在黄河下游河道砂坝或点砂坝上，观察到一种新的沉积构造，称为“粉砂蘑菇”。它们的形成过程被解释为通过冰的过程。这个名字，淤泥蘑菇来自他们的比喻形式。这是因为它们在大小和形状上看起来有点类似于蘑菇;直径在1至10厘米的范围内，中等3-5厘米，平均高度为10厘米，通常成群出现，偶尔在相对较软的淤泥中孤立。它们在从冬季到春季的过渡期发展，并且令人信服地与冰的过程有关。冰致淤泥蘑菇最好与许多其他新发现的冰致沉积结构（20多种）一起研究。显然，到目前为止，冰的过程被大大低估了。随着冰致淤泥蘑菇的大量发现，它开辟了新的问题。这是因为它的结构反映了岩石中发现的相同沉积结构，质疑它们的成因和沉积环境分析。这一成果不仅在沉积学上具有重要意义，而且在古地理学、古气候学、地质工程学、水力学和河流学等方面也具有重要意义。
Upon channel bars or point bars within the lows of the Yellow River, a new sedimentary structure, named ‘silt mushroom’, has been observed. The process of their formation is interpreted to be via the ice process. The name, the silt mushroom comes from their figurative form. This is because they look somewhat similar to mushroom’s in size and shape; being in the range of 1 to 10 cm in diameter, with the medium 3–5 cm, and on average 10 cm in height, occuring generally in groups, and occasionally in isolation in relatively soft silt. They develop in the transition from winter to spring, and are convincingly related to ice processes. Ice-induced silt mushrooms are best examined in association with the many other newly discovered ice-induced sedimentary structures (over 20 kinds). Clearly, up to now, ice processes have been significantly underestimated. With the substantial discovery of the ice-induced silt mushroom, it opens up new questions. This is because its structure mirrors the same sedimentary structures found in rocks, questioning their genesis, and sedimentary environment analysis. This achievement is significant not only in sedimentology, but also in palaeogeography, palaeoclimate, geological engineering, hydraulics and fluviology.
