Reconstruction of eroded monogenic Strombolian cones of Miocene age: A case study on character of volcanic aktivity of the Jičín Volcanic Field (NE Bohemia) and subsequent erosional rates estimation

Popis výsledku v původním jazyce

Relics of solitary volcanic edifices in NE Bohemia were newly interpreted as remnants of scoria cones and their conduits. Volcanic activity in this area occurred in a form of scattered Strombolian eruptions of basanitic magmas mostly ascending along E-Wtrending faults. Nearly all studied volcanoes erupted in similar style, Strombolian, mostly not producing larger lava flows. This volcanic activity took place mainly during Miocene (24.6-16.5 Ma). The lavas known on the Kozákov Hill were produced by muchyounger volcanic activity (6.7-3.5 Ma) and one of the studied locations is supposed to represent their feeder. The older Strombolian cones are relatively weakly affected by weathering processes. The erosional level at individual sites depends on geomorphology. On some of the edifices non-welded, poorly stratified scoriae are well preserved, at other sites a basal facies or upper vent facies were exposed by selective erosion. Interpretation of the exposed facies with the use of radiometr
