Textural and compositional variations in size fractionated Australian kaolins
En este artículo se relacionan todos los términos de la serie Mesozoica en el espacio y en el tiempo y se propone un modelo sobre su evolución sedimentaria, en el que se destacan algunos aspectos significativos del dominio paleogeográfico (Subbético Interno) al que pertenecía esta unidad. En este estudio se llega a determinar que en la Unidad de Si...
Volume 1, Terrain crétacé -- volumes 2, 3 et 4, Terrains tertiaires. Livres réalisé sur base des travaux d'André Dumont par M. Mourlon. Les 4 tomes reprennent un descriptif détaillé de toute la stratigraphie du Mésozoïque et Cénozoïque comme André Dumont l'a observé et décrit dans ses carnets lors de ses voyages en Belgique. Chaque tome aborde un c...

A great deal of Mesozoic hypobatholithic granites and hypabyssal porphyries develop in the Qinling Mountains. The former has long been regarded as transformation type (or S-type), and the latter associated with Mo-mineralization regarded as syntexis type (or I-type) granitoids. Statistics show that Sr1 and σ18O of hypabyssal porphyries respectively...

The Qinling Carlin-type gold deposit belt is the second largest Carlin-type gold ore concentrated area in the world and occurs in Mesozoic intracontinental collisional orogen, contrasting to the Carlin-type gold deposits in the Basin and Range province in Cenozoic active continental margin of West America. With ore-forming ages focussed at the rang...

An important tectonic inversion took place in eastern North China Block(NCB) during Mesozoic, which caused a great lithosphere thinning, reconstruction of basin-range series, powerful interaction between mantle and crust, a vast granitic intrusion and volcanism, and large-scale metallogenic explosion. The time range of the Mesozoic tectonic regime ...

Through studies ofP-T-t paths and decompressive retrograde metamorphic textures of metamorphic rocks in the East Qinling-Dabieshan region, the authors determined the Mesozoic crust rapid uplifting age, and then inferred that in the East Qinling-Dabieshan region lithosphere delamination occurred from T3 to J1. The Yanshanian granites produced by del...
