Harangi, Sz.: Major element chemistry of Lower Cretaceous igneous rock of Mecsek Mountains (Southern Hungary), I.

Petrochemical classification of igneous rocks in the Mecsek Mts. Besides phonolite the Mecsek Lower Cretaceous volcanic rocks were denominated as "trachydolerites" until the end of 1960s. MAURITZ (1913) distingusihed a high-silica "typical" and a low-silica "limburgitoid" group within the trachydolerites. BILIK (1966) revised the trachydolerite name and proposed the application of alkaline basalt, or — considering their appearance — alkaline diabase name. No more detailed studies were carried out on /o 40 f35 30 25 20 15 OT 10 TH OT CA A8 TD DSN FA AA TSA Fig. 2.
