PYROXENITE – MARBLE INTERACTION, A PETROGENETIC GRID AND A WORKING EXAMPLE FROM THE INĂU CRYSTALLINE ISLAND, MARAMUREŞ, ROMANIA. Authors: DANIEL M. RADU. |

Abstract: An exotic occurrence of a pyroxenite xenolith, hosted by dolomitic marbles is located in the Inău crystalline massif, Maramureş (Fig. 1). The interaction pyroxenite-marble at different PT has not yet been considered by the geological literature. Petrogenetic grids for ultramafic rocks were presented by Will et al. (1990), Schmaedicke, Okrusch (1997), Schmaedicke (2000). The most appropriate system (CaO-MgO-SiO2-H2O-CO2) was considered by Spear (1993). The mineralogical assemblages of the pyroxenite xenolith, the host rock and interaction zones are presented in the table 1. ... | |||||||
