Jp. Debenay et al., THE TEXTURE OF THE FORAMINIFERAL TESTS IN RELATION WITH THE CRYSTALLOGENESIS OF COLLOIDAL CALCITE, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 323(2), 1996, pp. 171-178
The basic elements of the foraminiferal tests always consist of globul
ar crystallites which organize into complex arrangements that may lead
to the formation of perfect crystals. This phenomenon is common in mi
neralogy and it has been reported for other minerals. The various text
ures of the foraminiferal tests, resulting from biological control cou
ld bear a relation with the evolution processes.
