Herewith we reconfirm the receipt, and acceptance, of the abstract entitled
"Zircon grains in A-type granite and their inclusions as recorder of upper mantle conditions in the Croatian segment of the Late Cretaceous collisional zone between Europe and Adria" that you have submitted for presentation at the CAM-2017 conference.
Interpolation map show temperatures of older metamorphic phase from greenschists of Medvednica Mt.
"Samples collected on the central part of Medvednica Mt. were analyzed with petrographic microscope in order to determine their microtextures and mineral composition. All the samples represent the greenschists, showing some differences in their mineral composition. Those differences were used to determine spatial changes of metamorphic conditions. Whole rock analysis was conducted on the sample from Sveti Jakob locality, in order to determine P-T conditions in which the rock was metamorphosed. Values calculated with Perple_X program package are 375°C and 430 MPa, matching the lower part of greenschist facies. Two different stages of deformation were recognized during the microscopic analysis, and the calculated values match the younger phase of deformation (D2) and the retrograde metamorphism. Microtectonic analysis of dynamic recrystallization effects visible within the plagioclase and quartz grans indicates the temperature conditions for the older deformation phase (D1) associated with prograde metamorphism. For the sample from Sveti Jakob locality, values range at 450-500°C, representing the upper part of greenschist facies. Few specific maps were made, showing spatial variations in metamorphic conditions for both phases of deformation, changes of magnesium and iron content in chlorites, variations in volume amount of mineral phases detected in samples, and distribution of minerals containing Fe3+."
