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.
