EN I For this week’s #TuesdayFieldMemories we would like to share a mylonitic calc-silicate from Southern Italian Alps (Forno Rosa Shear zone, in the Ossola Valley in Simonetti et al. 2023), courtesy of Dr. Stefania Corvo, which she will further discuss on our P-T- t talk session this Thursday. We see you there! Milonito calcissilicáticoContinue reading “[TFM] Mylonitic calc-silicate from Southern Italian Alps”

[TFM] Eocene molasse sediments from the Southern Carpathians
EN I Eocene molasse sediments from the Southern Carpathians (here the Conglomerate, in Romania) show some typical features of subaerial mass-flow deposits as coarse- to very coarse-grained lithofacies limited by multiple discontinuities, arranged in fining-upward cycles. Molasses sequences develop during the terminal stages of orogenic events. Fluvial and alluvial fans deposits are frequently identified asContinue reading “[TFM] Eocene molasse sediments from the Southern Carpathians”
[TFM] Pseudotachylite from the Juru shear zone (PB, Brazil)
EN I This #TuesdayFieldMemory is a pseudotachylite from the Juru shear zone (PB, Brazil) showing the main vein (centimetric) containing quartz and feldspar fractured clasts. From the main vein, injection veins oriented obliquely to its configuration are present, in which relitic grains of recrystallized quartz are observed. Contribution by Gustavo Viegas @lgviegas This rock andContinue reading “[TFM] Pseudotachylite from the Juru shear zone (PB, Brazil)”
