Mineralogical mosaics from the Carpathian–Pannonian region 6

Abstract

Further data are presented on mineral occurrences in the Carpathian–Pannonian region in this sixth instalment of the series arranged by countries and localities. Each “mosaic” contains a concise mineral description, mainly based on XRPD, SEM-EDX and EMPA measurements, and a brief characterisation of the mineral paragenesis. Some minerals are first-time descriptions from the entire discussed region, but all are newly documented occurrences from at least the de­scribed locality. From Hungary, mineralogical data are reported on churchite-(Y) from a hydrothermal ore indication in the granite near Pákozd, pumpellyite-(Fe³⁺) and julgoldite-(Fe³⁺) from the metabasite of the Darnó Hill in Sirok, and chamosite from manganese concretions in the Jurassic shale of Egerbakta. From Romania, the presence of the following minerals is recorded: reevesite from the serpentinized ultrabasic magmatite of Eibenthal in Banat, axinite from monzo­diorite of Groșii Ţibleşului, and braunite from a manganese deposit in the Jurassic sediments of Buceava-Şoimuş. We present the data of evenkite from the fissures of Mesozoic sandstone near Oporets, Ukraine, which was found in calcite fillings in association with hydrocarbon-containing quartz (“Marmarosh diamond” variety).
