Description
| - High-Ti melanephelinite, medium-(phono)tephrite, and low-Ti basanite are specific rock types in the Cenozoic Volcanic Province. A contrasting melanephelinite to (phono)tephrite series occurs in the Loučná–Oberwiesenthal Volcanic Centre associated with basanites on the SW periphery of the Krušné hory. The volcanic rocks intrude the Variscan basement of the uplifted shoulder of the Ohře/Eger Rift. Low Mg and Cr, Ni contents and enrichment of incompatible elements in the high-Ti melanephelinites contrast with the composition of primitive low-Ti basanites displaying high Mg and high contents of compatible elements. The large variation in initial strontium isotope ratios of high-Ti melanephelinites at similar epsilon Nd values is interpreted as evidence for melting of metasomatized lithospheric mantle sources comprising K-bearing phases with radiogenic Sr. The initial isotope ratios of all samples are consistent with HIMU-mantle sources and contributions from lithospheric mantle.
