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.

Central Bohemian Pluton (CBP) 1.02. Satellite Stocks and Dyke Swarms 1.03. Igneous Rocks in the Roof of the Central Bohemian Pluton (2.2.) Ultrapotassic Plutonites (see the Moldanubicum section) Regional position: CBCB intruded along the Central Bohemian Suture between the Moldanubian Zone and Teplá-Barrandian Unit (Bohemian Zone). Its members, the Říčany Massif, Durbachite Plutons (the Milevsko and Tábor Massifs), Benešov Massif and SW part of the Blatná and Červená Granodiorites intruded the Moldanubian Zone. The typological classifications of CBCB rock types (see references) are based on their petrographic, chemical, and mineralogical composition (e.g. Palivcová 1965, Steinocher 1969, Vejnar 1974, Holub et al. 1997, Janoušek et al. 2000b). The CBCB comprises according to Janoušek et al. (2000b) five granitoid suites: Sázava suite (Sázava, Marginal and Požáry intrusions), Blatná suite (the Blatná with the Červená facies, Těchnice and Kozárovice facies), Čertovo břemeno
