Geologica Acta
Geologica Acta (ISSN 1695-6133 / 1696-5728 e-ISSN) is an institutional open access journal, international and a general profile of Earth Sciences. The journal welcomes articles from both conceptual and regional levels, with special emphasis on areas of the Mediterranean, South America and the Caribbean, but without considering contributions from any region. Also encouraged the publication of theme issues that give the results of projects and international scientific meetings.

14 p, 2.0 MB Trace element analysis provides insight into the diets of early Late Miocene ungulates from the Rudabánya II locality (Hungary) / Eastham, L. C. (University of Toronto. Anthropology Department) ; Feranec, R. S. (New York State Museum. Research and Collections) ; Begun, D. R. (University of Toronto. Anthropology Department)
The early Late Miocene vertebrate locality of Rudabánya II (R. II) in northeastern Hungary preserves an abundance of forest-adapted ungulate species. To better understand the ecological relationships within this ancient ecosystem, we used analysis of enamel strontium/calcium (Sr/Ca) ratios to infer dietary preferences. [...]

(Universidad de Caldas (Colòmbia). Departamento de Ciencias Geológicas) ; Barbosa-Espitia, A.A. (Universidad de Caldas (Colòmbia). Departamento de Ciencias Geológicas)
Typology and internal texture analyses were performed on detrital zircons obtained from the Miocene sandstones of the Ladrilleros-Juanchaco sedimentary sequence (Colombia, Equatorial Pacific). This analysis was complemented with zircon U/Pb dating to identify typology-age associations as indicators of provenance of these sediments. [...]

A new ichnotaxon, Lapillitubus montjuichensis n. i gen. n. isp. , is described from the middle Miocene (Serravallian) of Montjuïc mountain (Barcelona, northeastern Spain). This ichnotaxon consists of a horizontal to vertical, cylindrical burrow with an agglutinated lining exclusively composed of lithoclasts. [...]

(Aligarh Muslim University. Department of Geology) ; Ahmad, A. H. M. (Aligarh Muslim University. Department of Geology)
Lithofacies and granulometric analysis were carried out to decipher the depositional environment of the Fort Member of the Jurassic Jaisalmer Formation. Based on field data nine lithofacies have been identified including trough cross-bedded sandstones, planar cross-bedded sandstones, matrix supported conglomerates, thinly bedded siltstone and sandstones, herringbone cross-bedded sandstones, wave rippled sandstones, laminated sandstones, hummocky cross-bedded sandstones, limestones and shales.
