Magma flow paths and strain patterns in magma chambers growing by floor subsidence: a model based on magnetic fabric study of shallow-level plutons in the Štiavnica volcano-plutonic complex, Western Carpathians
Original language description
The Miocene Štiavnica volcano-plutonic complex, Western Carpathians, exposes two nearly coeval intra-caldera plutons, their roof (basement of a stratovolcano), and associated volcanic rocks. The complex thus provides insights into mechanisms of magma chamber growth beneath large volcanoes. As inferred from the anisotropy of magnetic susceptibility (AMS), these plutons were emplaced through significantly different processes: the diorite as a discordant stock with steep fabric and the granodiorite as a tabular, bell-jar pluton. In detail, we interpret that the latter was assembled in two stages. First, an upper "layer" intruded as a thin sill along a major subhorizontal basement/cover detachment. The subhorizontal magnetic fabric and strongly oblate AMSellipsoid in this layer record intrusive strain where the magma flow paths were subparallel to the pluton roof. Second, in the lower "layer" of the pluton, magnetic foliations dip moderately to the similar to NW and similar to WNW to vert
