encrustatsiooni
Encrustatsiooni is a term used in geology and paleontology to describe the process where a mineral substance or sediment coats or fills the cavities of a rock or fossil. This coating can occur in various ways, often involving precipitation from groundwater or the deposition of fine-grained material. In geological contexts, encrustations can form on the surface of rocks, gradually building up layers over time. This is frequently seen in caves where mineral-rich water drips and deposits calcite, forming stalactites, stalagmites, and other speleothems.
In paleontology, encrustations are significant for their ability to preserve the shape and details of organisms.
