Alegret, Ortiz & Kaminski (eds.), 2012. Ninth International Workshop on Agglutinated Foraminifera, Abstract Volume<br />
With respect to similar techniques that perform SEM and EDS analyses mostly on the<br />
agglutinated wall surface (e.g. Murray 1994, Bertram and Cowen, 1998; Thomens and<br />
Rasmussen, 2008; Makled and Langer, 2009; Gooday et al., 2010; Pawlowski and Majewski,<br />
2011) our method focussed on the cross section for: (i) documenting the internal chamber<br />
setting and their morphological features; (ii) measuring the shell thickness and the grain<br />
distribution; (iii) emphasizing the presence of parapores penetrating the test walls; (iv)<br />
detecting the chemical composition of the grains and the cement, in order to eventually<br />
highlight a mineralogical selection/arrangement.<br />
Taking advantage of a multidisciplinary threefold approach with a telescopic<br />
increasing resolution, we propose this methodology as a standard approach in<br />
micropaleontological studies addressed to better understand test microstructure and<br />
composition of fossil agglutinated foraminifera.<br />
