15 p, 2.1 MB Depositional environment of the Fort Member of the Jurasic Jaisalmer Formation (western Rajasthan, India), as revealed from lithofacies and grain-size analysis / Ahmad, F. (Aligarh Muslim University. Department of Geology) ; Quasim, M. A. (Aligarh Muslim University. Department of Geology) ; Ghaznavi, A. A. (Aligarh Muslim University. Department of Geology) ; Khan, Z. (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.

55 p, 24.4 MB Structural and facies architecture of a diapir-related carbonate minibasin (lower and middle Jurassic, High Atlas, Morocco) / Teixell Cácharo, Antonio (Universitat Autònoma de Barcelona. Departament de Geologia) ; Barnolas, Antonio (Instituto Geológico y Minero de España) ; Rosales, Idoia (Instituto Geológico y Minero de España) ; Arboleya, María Luisa (Universitat Autònoma de Barcelona. Departament de Geologia)
We report the structural geometry and facies architecture of a small diapir-related carbonate-dominated basin from the Jurassic rift of the Moroccan High Atlas. The Azag minibasin is a lozenge-shaped depocenter completely enclosed by tectonic boundaries that we interpret as welds after former salt anticlines or salt walls. [...]

15 p, 1.2 MB An overview on Callovian-Cenomanian intracratonic basins of Northeast Brazil : onshore stratrigraphic record of the opening of the southern Atlantic / Valença, L. M. M. (Universidad Federal de Pernambuco. Departamento de Geología) ; Neumann, V. H. (Universidad Federal de Pernambuco. Departamento de Geología) ; Mabessone, J. M. (Universidad Federal de Pernambuco. Departamento de Geología) ; Neumann, V.H. ; Mabessone, J.M.
A number of small Callovian-Albian sedimentary basins occur in the NE-trending Araripe-Potiguar topographic lowlying area. These basins developed in a fairly narrow zone of Precambrian supracrustal rocks from the Middle Jurassic onwards, as a consequence of the reactivation of ancient fault lines. [...]

Departament de Geoquímica, Petrologia i Prospecció Geològica) ; Consejo Nacional de Investigaciones Científicas y Técnicas (Argentina)
Isotopic analysis can be used to interpret the origin of evaporitic sediments. A preliminary isotopic study of strontium, oxygen and sulphur has been carried out in Ca-sulphate facies of Jurassic marine evaporates (Tábanos Formation and Auquilco Formation) outcropping in southern Mendoza, Aconcagua-Neuquén Basin (Argentina), as a part of a comprehensive sedimentologic study.
