Middle Triassic magmatic sequences from different tectonic settings in the Bükk Mts., NE Hungary
In the Biikk Mts. (NE Hungary) two Middle Triassic magmatic event can be detected. In the first phase of the magmatism (Upper Anisian — Lower Lanidian) lava flows and pyroclastics with andesitic-rhyolitic composition were produced, while the younger magmatic horizon (Upper Lanidian — Lower Camian) i...

| Tartalmi kivonat: | In the Biikk Mts. (NE Hungary) two Middle Triassic magmatic event can be detected. In the first phase of the magmatism (Upper Anisian — Lower Lanidian) lava flows and pyroclastics with andesitic-rhyolitic composition were produced, while the younger magmatic horizon (Upper Lanidian — Lower Camian) is represented by basaltic lava flows and subvolcanic intrusions, as well as some basic tuffs. On the basis of the major and trace element characteristics and the chemical composition of the clinopyroxenes, the first phase shows calc-alkaline orogenic, while the second has within-plate alkaline affinity. |
