Precambrian- Quaternary profiles which were expanded in Bolivia mainly consist of Precambrian- Devonian, Ordovician- Silurian and Devonian, Carboniferous, Cretaceous, Tertiary and Quaternary sedimentary rocks. Furthermore, the igneous and metamorphic rocks include unseparated Precambrian rocks, Paleozoic- Mesozoic bulks, Cretaceous- Tertiary and Quaternary volcanics in southern west of Bolivia. The other sedimentary rocks can be found in eastern and southern east. Some geological studies and researches performed in Bolivia are greatly important due to the main effect of Andes Mountain orogenese in western ranges and center of Bolivia. Although there are a large number of other geological projects should be carried out in north of Bolivia. Here, a geology map of Bolivia was prepared which has low precision in southern parts.

Since Bolivia is very near to the western range of South America, Andes orogenesis has an important effect shown in different forms such as tectonic and topography changes and erosion.
Note that since Bolivia is in the central part of Andes, earthquakes occur in this region are far from center of landslides and have a great focal depth.
Due to the boundaries and geographical location of Bolivia compared to other countries, it can be concluded that the greatest earthquakes occur in 150 to 300 km depth and are less disastrous because of great focal length.

Using the paleomagnetic data of eastern south of Peru and east of "Cordilera" region in Bolivia, it was estimated that this region belonged to Pre-Cretaceous to Paleocene.
