Lower Silesian Branch of the Polish Geological Institute (OD) was founded in 1949, 70 years ago.

In the 1970s until the end of the 1990s, during the period of the OD stabilization, the implementation of regional geological surveys started with the use of geophysical methods and deep drilling. These studies were conducted in the majority of tectonostratigraphic units – in the North Sudetic and Central Sudetic depressions, in the upper Nysa Kłodzka graben, in the Bardo structure and in the area of Foresudetic block. Geological and cartographic works on a scale of 1 : 25,000 and 1 : 50,000 covered the entire area of Lower Silesia. In the mid-1990s, the edition of the Map of 1 : 25,000 (134 sheets) was finalized, and the reambulation of Maps 1 : 50,000 (43 sheets) in 2009.
