The Late Jurassic Marib Al Jawf Basin is part of a rift system extending southeastwards into the less well k n o w n Wadi Hajar Basin. This rift system may be one arm of a Late Jurassic failed triple rift which also included the Masilah Basin to the east, and the Sir Basin to the north. Late Jurassic rifting is shown to be diachronous, younging eastwards. Renewed rifting during the Early to Mid Cretaceous was accompanied by deposition of the newly recognized Furt Formation. This second rift phase initiated movement on the N -S striking 47°E Fault, w h i c h probably extends southwards into Somalia. Extension in the J e z aHowarime Rift System may also have c o m m e n c e d at this time. Oman Mountain orogenesis led to r e n e w e d subsidence in the east, and was followed by polyphase Tertiary rifting, inversion and localized gravity-driven extension on the continental margins. As a result of these events, a number of distinct petroleum systems developed.

Summary A series of thrust and shear zone structures in the upper Pennine Alps dissect the area into a number of horsts and duplexes. The diversity of the mineral stretching lineation directions when combined with shear-sense indicators reveals substantial variation in the movement direction both between and within different units, and in some cases at different times within the same unit. The present-day geometry, illustrated in a new block diagram, is controlled largely by backthrusts. These backthrusts have overprinted, and in some cases reactivated, earlier, more ductile forethrusts and cut out all but one of the regional megascopic folds. While this backthrusting renders structural analysis of the early history of the area intractable, study of the petrogenesis of early, high-pressure assemblages yields some data. Deformation during subduction, leading to the subcretion of rock packets onto the over-riding plate is recorded by a ‘hairpin’ in the P-T paths of several units, and by a few relic structures within ophiolite units. The forms of P-T paths for units which have undergone high pressure metamorphism indicates that they underwent similar histories. Geochronological data for this area are as yet of insufficient resolution to decide if the tectonometamorphic events were continuous or episodic.

Biobank participation of children is an ethically complicated process as the vulnerability of this population is a concern throughout the entire process of biobanking. Some ethical issues are more prominent in pediatric biobanking and may not need to be considered in biobanking of adult specimens and data. These include assent, reconsent at the age of majority, capacity to consent, and consequences of genetic results on the child and family members. This article describes current processes and best practices described in the literature as well as our experience at the BC Children's Hospital BioBank, a pediatric institutional biobank in Vancouver, Canada. The focus is on processes more specific to pediatric biobanking, such as assent, as well as topics that affect the pediatric population differently compared to adult biobanking.
