This issue of The International Journal of Clinical Pharmacology and Therapeutics commemorates the 60th Anniversary of the book “Facies dolorosa” published in an extended and unabridged edition in 1956 by Dustri Medical Science Publications [1]. The contents of this unique and highly sought after book, compiled and annotated as a contribution to medical research and teaching by the surgeon and ...

Understanding how changes in fluvial and marginal marine architecture correlate with shifts in marine shoreface architecture is a crucial step to understanding the effect of relative sea level changes on terrestrial sedimentary systems. Three measured sections (each >230 m), 2367 paleocurrent measurements, and examinations of lateral facies relationships were made over 3 km of continuous outcro...

Several AVO cross plot methods were compared using well data from 5 exploration drilled in deep water block in Krishna-Godavari basin. This study shows that AVO Impedance vs. Acoustic Impedance cross plot provides the best separation between gas bearing sands, water bearing sands and shale/clay. AVO Impedance (AVOI) attribute derived by normalizing the Acoustic Impedance (AI) and Elastic Impeda...

The use of gravels as syntectonic indicators of thrusting has recently been questioned by foreland-basin models that assign gravels to a post-thrusting interval of progradation, except in very proximal areas. On the basis of precise temporal control provided by magnetostratigraphically dated sections, the history of gravel progradation after a major thrusting and uplift event in the northwester...

The Eocene rocks in Shabraweet area comprise the Lower, Middle and Upper Eocene stages. Each stage consists of only one rock unit; the Minia Formation, the Mokattam Formation and the Maadi Formation, respectively. The Minia Formation shows angular unconformity relationship with the underlying Cretaceous rocks and disconformity relationship with the overlying Mokattam Formation. The Maadi Format...

Metamorphism along the southern margin of the Archean Superior Province has been historically attributed to the Penokean orogeny. A narrow corridor of amphibolite facies rocks north of the main suture does record 1.83–1.80 Ga metamorphic monazite U–Th–Pb ages that mark the culmination of arc accretion. However, subsequent widespread amphibolite facies metamorphism and associated magmatism is re...

Collins, L.B., Zhu, Z.R., Wyrwoll, K.-H., Hatcher, B.G., Playford, P.E., Eisenhauer, A., Chen, J.H., Wasserburg, G.J. and Bonani, G., 1993. Holocene growth history of a reef complex on a cool-water carbonate margin: Easter Group of the Houtman Abrolhos, Eastern Indian Ocean. Mar. Geol., 115: 29-46. The Houtman Abrolhos reefs, situated on the western continental margin of Australia, occupy a tra...

Abstract The research focuses on the Klapanunggal Formation, composed of limestone in West Java Basin, specifically area, District, Bogor Regency, Province. A massive outcrop was found this location. method used is field data collection, stratigraphic cross-section measurement, and petrographic analysis. It aims to determine facies characteristics, depositional environment, association Formatio...

In this paper, metamorphic conditions (T, P and fluid composition) in greenschist to amphibolite facies transition zone are investigated using textural evidence, compositions of the minerals and phase diagrams. Metabasits from the south of Kordestan province were metamorphosed from sub-greenschist to upper amphibolite facies. Field observations and petrography studies show that there are some r...
