Idanre area which is situated within the Nigerian shield affected by orogenic activities accompanied emplacement of Pan-African granitoids. This paper presents a new information on geochemical behaviour Rare Earth Elements (REEs) and High Field Strength (HFSEs) Zr-Hf Y-Ho that can explain post magmatic processes relating to origin evolution granite. Zr-Hf, Hf-(Zr/Hf) Y-Ho, (Y/Ho)-Ho variation d...

Abstract Sequence identification and division is an important basis for oil gas exploration research. In view of the complex sedimentary environment, based on previous element logging correction lithology, through combination curve lithology data, in this paper, two methods maximum entropy spectrum analysis wavelet transform are used to identify divide interface, high-resolution sequence migmat...

In this guide key outcrops of the Maures Massif, southernmost part Variscan belt in France, are described. Here features acquired during fundamental steps evolution southern European can be recognised. The field trip develops along a W to E transect, perpendicular main architecture belt. It is organised eight stops that easily reached by car or walking. excursion completed one day, but better e...

Post-orogenic extension in back-arc regions is classically associated with metamorphic core complexes (MCCs) cored exhumed rocks and granitic intrusions interacting low-angle detachments. When additional heat provided by the advected asthenosphere below extending region, for instance above slab tears, high-temperature migmatite-cored domes composite are emplaced whose geometry kinematics of emp...
