The starting point for this work is the concept of geological faults, with a closer approach to some of the rocks typically found in the earth’s crust .

The objective is to oppose the large-scale vision of a geological fault – with a naturalistic graphic approach – to the vision of approximation of the elements which compose it.

Therefore, the rocks are drawn as geological fragments in the naturalistic approach of a field notebook, with the aim to explore and understand their construction of shapes and colors.

This exploration involves getting to know the material under study as part of the process of building a scientific illustration, whose aim is to know the shapes, proportions, colors, with both drawing and written annotations, which provide extra information about the models.The rocks chosen for the project are the most common in Portugal. These are divided into three types:

⍚ Magmatic (igneous) rocks result of the solidification of magma on the surface or in depth, due to the drop in pressure or temperature: Basalt, Gabbro, Granite and Ryolite

⍚ Sedimentary rocks formed by the deposition and consequent cementation or consolidation of mineral and organic fragments: Clay, Sandstone and Limestone

⍚ Metamorphic rocks result of the transformation of an original rock, by the action of high temperature and pressure: Anthracite, Slate, Shale, Marble and Gneiss.
