Geology of Latvia Geology of Latvia The geology of Latvia includes an ancient Archean and Proterozoic crystalline basement overlain with Neoproterozoic volcanic rocks and numerous sedimentary rock sequences from the Paleozoic, some from the Mesozoic and many from the recent Quaternary past. Latvia is a country in the Baltic region of Northern Europe. Several hundred boreholes have returned data about the Precambrian crystalline basement of Latvia, indicating young Middle Proterozoic intrusive rocks such as 1.65 billion year old rapakivi granite or 1.82 billion year old granodiorite in the northeast. Most basement probably formed before the Svecofennian orogeny, between the Archean and Proterozoic. The
