ABSTRACT: The present work is a systematic study of 37 species of NeogastropoDa from different pliocene outcrop (Zanclean) from Huelva (Guadalquivi~ Bassin). Also presented are their abundance, chronostratigraphic, bathymetric and geographic distribution together with the substrate type, nutrients and recent citations in the Spanish Pliocene.

ABSTRACT: The studied area is considered as a border zone of the so called ~Domo Anatéctico del Tormes~ (central western Spain)~. This zone is mainly made up of pelitic migmatites and several types of anatectic hercynian granites. In the present work these rocks are characterized petrographically. Taking into account petrographic and structural criteria, in some cases a likely protolith anatexite (granite) correspondence is established. Thus, autocthonous granite belts could represent different types of gneisses. From this litho stratigraphic point of view, the following sequence is inferred; coarse grained anatexites - medium grained diatexitic granite or glandular gneiss - fine grained anatexites or migmatitic paragneiss-pelitic migmatite.

ABSTRACT: The studied area is located in the Spanish sector of The Chaves Miranda do Douro hercynian antiform (central western Spain). From a structural point of view, an interfereoce model of folding between phase II, with an associated flat foliation, and phase III with folds of subvertical axial planes is inferred. A lithostratigraphical sequence is proposed, from botton to top: biotitic glandular gneiss leucocratic glandular gneiss (porphyroblasts becoming scarce) fine grained paragneiss pelitic gneiss and metapelites with quarzitic, metatonalitic and metabasitic interbedded rocks. A petrographic, and in some cases, geochemical, characterization of all these rocks is made. This suggests a probable P T t metamorphic path, from a greater pressure metamorphism (with staurolite relicts) to a second one, with sillimanite, cordierite, or andalusite, During this latter metamorphism (late phase III) anatectic conditions are attained, and frequently gneisses progress to metatexites and diatexites. Thus, it is possible to infer some kind of protolith anatexite correspondence such as paragneiss fine grained granite and pelitic rocks porphyritic granite.

ABSTRACT: The Pelomedusids are the most abundant Chelonia from the Duero basin, not only for their geographic distribution but for being of constant appearance in all the outcrops.
The chelonian fauna, Lower Eocene (Upper Neustrian to Middle Rhenanian, both included) in age, is well represented in the Zamora province (Spain), within this chelonian fauna three type of clustering can be proposed, defined by the presence, in the some outcrop, of Carettochelyds or Trionychids (never found together) with Pelomedusids of two different sizes (which, again, never are found together).
The small Pelomedusids (from about 20 to 25 cm in adult individuals) are known as Neochelys zamorensis, since 1981, but this name is not valid up to 1992, to which a figure of the type specimen, now described, is published.
Neochelys zamorensis Jimenez is very close to Neochelys arenarum Broin 1977, just differing in some details of the plastron and the carapace. The cranial features have not been compared.
