This geosite is an outcropping found in the slope of the road near the settlement of Chao de Espinho. It is a location which proves the even earlier state of the evolution of orthogonal fracturing of the Quartz Diorite Mass. The network of joints of this body divide it into smaller and larger blocks, which look like thick street tiles. The weathering is even more accentuated on the joint surface planes given the more intense circulation of infiltration waters. Given that the degree of weathering of the vertices is greater than of the sides, the blocks tend to become increasingly rounded and then separate from one another. Here the separation characteristic "onion peel" can be clearly observed, in which the most external surface is much more sanded in contrast to the less altered quartz diorite in the nucleus of the block.
