Petrogenetic evolution of mesosiderite NWA 8741

Olga A. Ageeva, Cyril Lorenz, Gerlinde Habler, Lutz Nasdala et autres

Abstract Two samples of the meteorite Northwest Africa 8741 (NWA 8741) were investigated using petrographic, mineral chemical, and crystal orientation analysis to reconstruct its evolution. NWA 8741 is an A4 mesosiderite composed of lithic clasts of pyroxenite and single‐grain porphyroclasts of olivine …

Formation of ekanite in “antiskarn” by carbonatitic melt infiltration into charnockitic gneiss, Ampegama, southwestern Highland Complex, Sri Lanka

K. A. Geeth Sameera, Christoph A. Hauzenberger, G.W.A. Rohan Fernando, Radek Škoda et autres

Abstract Carbonatitic melt–rock interactions in the crust provide key insights into element mobility, metasomatic processes, and the formation of rare mineral assemblages in high-grade metamorphic terrains. Ekanite-containing calc-silicate dykes at Ampegama, southwestern Highland Complex, Sri Lanka, provide compelling evidence for the interaction …

Comment on egusphere-2025-1810

Magee, Jr, Charles W., Lutz Nasdala, Renelle Dubosq, Baptiste Gault et autres

Abstract. Chemical abrasion, a two-step process of annealing and partial dissolution, is routinely applied to zircon grains prior to U-Pb geochronology, to remove portions of the grains affected by Pb loss. The exact effect of this technique on the zircon structure and …
