The Cracow - Wieluń Upland, commonly known as the Jurassic, makes part of a vast Silesian - Cracow Upland. The length of the strip stretching from the vicinity of Wieluń to Cracow comes to 160 km, with up to 20 km average width (in the north - up to several kilometres, in the area of Krzeszowice - 40 km). In the west, the Jurassic borders on the Silesian Upland and the Oświęcim Valley which get separated from the Jurassic by a denudative rock step (quite high in places) reaching up to 100 m (called also a 'kuesta' whose one slope is long and mild, while the other is very short and steep). The western border of the area is formed by a line linking one by one the following towns from the north: Wieluń, Krzepice, Kłobuck, Częstochowa, Żarki, Myszków, Zawiercie, Ogrodzieniec, Olkusz, Trzebinia, Babice.

In the east, the Cracow -Częstochowa Upland borders on the Miechów Upland, the Nida Basin, and its borderline runs along the Dłubnia Valley through Maków, Żarnowiec, Pradła, Lelów, Janów, Mstów, Kruszyna, Pajęczno to Wieluń. On account of its geomorphological differences, the Jurassic can be divided into two uneven parts: northern and southern. The Northern Cracow Upland includes: the Wieluń Upland, the Częstochowa Plateau, the Ojców Plateau; the Southern Cracow Upland contains: the Krzeszowice Trench, the Tenczynek Prominence and the Cracow Gate.

The Wieluń Upland stretches from Wieluń to the Warta ravine in the vicinity of Częstochowa, and is characterized, in comparison with other parts of the Jurassic, by little variety of landscape. First of all, there are no inselbergs typical of the Cracow Upland, which occur only occasionally in the Warta ravine close to Działoszyn. Flat hills do not exceed the height of 260 m. above sea level.
