Essai d'analyse elementaire de la theque de Trigonopyxis arcula (Leidy) Penard (Rhizopoda, Testacea)
The shells of T. arcula were analysed qualitatively using the probe of a scanning electron microscope and Castaing's microprobe analyser. The elements Al, Si, K, Ca, Fe, Ti, Cl, S and Mg were detected at several points, and along the diameter. The respective densities are illustrated by distrib...

Summary: | The shells of T. arcula were analysed qualitatively using the probe of a scanning electron microscope and Castaing's microprobe analyser. The elements Al, Si, K, Ca, Fe, Ti, Cl, S and Mg were detected at several points, and along the diameter. The respective densities are illustrated by distribution maps (X-ray pictures). These analyses do not disturb the structure of the shells. The results are compared to those of Nebela tincta, Euglypha sp., Phryganella acropodia and Centropyxis aerophila. |
