pehmenevad

Pehmenevad is a rare or obsolete term referring to a type of stone or rock formation found in Estonia and Latvia. The term is derived from the Estonian word "pehme," meaning soft, and "nevad," referring to a specific type of rock or dolostone.

Pehmenevad formations are characterized by a soft, porous, and easily weathered stone that can be found in areas with high levels of groundwater or where the rock has been subject to significant erosion over time. These formations typically consist of a type of dolostone that has been altered by the presence of water, resulting in the breakdown and softening of the rock.

Pehmenevad formations can be found in various locations throughout Estonia and Latvia, with the largest deposits found in the northeastern parts of Estonia. They often occur in areas of quicksand or soft mud, where the water table is close to the surface, and the rock is subject to constant moisture and erosion.

In the past, pehmenevad formations may have been used as a source of building materials, such as mortar or aggregate. However, their fragile nature and tendency to disintegrate make them unsuitable for modern construction purposes.

Pehmenevad formations are considered a unique geological feature of the region and can provide valuable information about the area's geological history. Their rarity and limited occurrence make them a fascinating subject of study for geologists and naturalists. Despite their fragility, pehmenevad formations continue to be an important part of the region's natural and cultural heritage.
