Zusammenfassung

Der vorliegende Beitrag befa\t sich mit der Zusammensetzung von Spurenmineral-Einschlüssen in Cassiteriten einiger Greisen und vergreister Gesteine aus dem Homr Akarem Gebiet der Eastern Desert, Ägypten. Untersuchungen mit dem Rasterelektronenmikroskop, Röntgenspektralanalysen und Mikrosondenanalysen ergaben, da\ diese Einschlüsse Nb-Ta, Nb-Ti, Ta-Ti und Fe-Ti sein müssen, neben Ti- und Fe-Mineralen.

Abstract

The present communication deals with the composition of the trace minerals inclusions encountered in the cassiterite of some greisen and greisenized rocks at Homr Akarem area, Eastern Desert, Egypt.

SEM studies, X-ray spectral analysis and EMP analyses revealed that these inclusions are to be Nb-Ta, Nb-Ti, Ta-Ti and Fe-Ti besides Ti and Fe minerals.

Résumé

Cette contribution a trait à la composition des inclusions minérales en trace dans la cassitérite de quelques greisen et roches gresinifiées dans la région de Homr Akarem, désert oriental, Egypte.

Des etudes SEM, des analyses spectrales aux rayons X et des analyses EMP ont montré que ces inclusions sont des minéraux Nb-Ta, Nb-Ti, Ta-Ti et Fe-Ti en plus de minéraux Ti et Fe.
