Algac back to ToC or Class ToC

IRI: https://w3id.org/nsd#Alga

Algae are microscopic vegetal organisms without stem or leaves which can be seen outdoors and indoors, as powdery or viscous deposits (thickness : tenth of mm to several mm). Algae form green, red, brown, or black veil like zones and can be found mainly in situations where the substrate remains moistened for long periods of time. Depending on the environmental conditions and substrate type, algae may form solid layers or smooth films. On monuments, algae are constituted of unicellular to pluricellular clusters, and they never form macroorganisms.

Differential erosionc back to ToC or Class ToC

IRI: https://w3id.org/nsd#DifferentialErosion

occurs when erosion does not proceed at the same rate from one area of the stone to the other. As a result, the stone deteriorates irregularly. This feature is found on heterogeneous stones containing harder and/or less porous zones. It may also occur as a result of selective lichen attack on calcitic stones. Differential erosion is generally found on sedimentary and volcanic stones. Differential erosion is synonymous with relief formation, i.e. the formation of irregularities on the stone surface. Differential erosion may result in loss of components or loss of matrix of the stone
