Concept of pebble

November 18, 2012


In the text of Delanda we can see that one of the most important example he gives is about sedimentary rock. We will look closer to see how it could be helpful for the architecture projects.

 “In geological stratum, for example, the first articulation is the process of ‘sedimentation’ which deposits units of cyclic sediment according to a statistical order: flysch, with its succession of sandstone and schist. The second articulation is the ‘folding’ that sets up a stable and functional structure and effects the passage from sediment to sedimentary rock.” Deleuze and Guattari 1987, Enphasis in the original.

 “Folding is, indeed, a second articulation but one operating at different scale, that of folded mountain ranges (like the Himalayas), in which the first articulation is the statistical accumulation of many layers of sedimentary rock.” Delanda  P.163

Folding as an accumulation of layers is what you can see when you look to mountain from the sky. In that way you can observe the history of the geological form. When you work with the project in the analysis of the city for example you are looking to explode the city in different layers. Tracing paper is one of most important tools for the architect. Layers help you to organize the project and make a trace of the history of the project, from the concept to the changes. With the tracing paper or layers you can dissect the project and have a clear idea of the way you think the project. Looking back to the first idea, the first layer makes the concept stronger and the project better.

“In its simplest form double articulation involves a relation between spatial scales: sedimentary rock, the final product in the example given above, has clearly a greater extension than the pebbles that serve as raw materials for its synthesis.”Delanda  P.165

We can say that the pebble can be the architectural concept, pure idea, strong and indivisible. In the contrary sedimentary rocks are deposited in layers as strata . The study of sedimentary rocks and rock strata provides information about the subsurface that is useful for civil engineering , for example in the construction of roads, houses, tunnels, canals or other constructions. Sedimentary rocks are also important sources of natural resources like coals, fossils fuels,drinking water or ores. Sedimentary rock is useful as it is for architects. We can also see it as a metaphor of the end of a project : a complex mix of material, in space and time.
