Kinematic analysis of deformation. B. Natalin. Structural geology and tectonics. Structural geology is the study of deformation of rocks. - we study such features as folds, faults, their geometry, movements, origins;. A rock is a natural substance that is made up of solid crystals of different minerals that have been fused together into a solid lump. . Rocks can be classified by their attributes: . Texture.

Clastic sedimentary rocks are accumulations of clasts: little pieces of broken rock which have been piled up and "lithified" by compaction and cementation.. Do Now. 1.  What is an igneous rock?. 2.
