Preservation of original aragonite structure in esmophylium castellolense (Scleractinia) from the Eocene Igualada Basin (Spain) Álvarez Pérez, A. (Aurelio) ÁlvarezPérez, German Scleractinian corals produce an aragonite skeleton that is usually converted to calcite by diagenetic processes after death. However, examples that have preserved the original aragonite skeleton and its original microstructure have been found in the Igualada Basin (NE Spain). The species Desmophyllum castellolense is described and analyzed. X-ray diffraction was used to confirm the skeletal aragonite and analyze the associated elements. The microstructure of the skeleton is described using polished and thin sections with the aid of scanning electron microscopy (SEM) and optical microscopy. The description of this species is taken from Álvarez Pérez, 1993, Álvarez Pérez, 1997. 2021-05-17T11:52:47Z 2021-05-17T11:52:47Z 2021-05-17T11:52:47Z 2014-04-18 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 1871-174X http://hdl.handle.net/2072/450004 https://doi.org/10.1016/j.palwor.2014.04.001 eng Palaeoworld, 23 (2014), p. 327-335 info:eu-repo/semantics/openAccess Copyright © 2014 Elsevier B.V. and Nanjing Institute of Geology and Palaeontology, CAS.
