One of the principal characteristics of the Bohemicum (Teplá-Barrandian Unit) is the relative scarcity of plutonic rocks, which are so frequent in the Moldanubicum and Saxothuringicum. The overall positive gravity field of the whole area indicates that plutonites are missing also in deeper crustal level (Dudek 1995). According to Dudek (1995) the individual plutonites may be divided into two groups: (a) basic massifs with acidic differentiates, and (b) granitoid massifs. The presence of pre-Variscan (Cadomian) and Variscan members is taken for granted in both groups. According to Holub et al. (1995), the Central Bohemian Composite Batholith (Central Bohemian Plutonic Complex) is considered to be part of one of the principal magmatic complexes not only in the Bohemicum but also in the Bohemian Massif.
