Recent works by the Norwich group (Gunning et al., 1999 Mackie et ak, 1999, 2000 Wilde, 2000) have demonstrated how surfactants disrupt and displace proteins from an interface by a three-stage "orogenic" mechanism. We have adopted this mechanism to describe spread protein-LMWE mixed films (Figure 14.8) (Patino et al., 2003). The results suggest that for spread...

Even though paleoaltimetric data from internal structural elements of orogenic belts and plateaus represent much needed complementary information to those derived from surface deposits or weathering products we caution about the uncritical use of stable isotopic data from deeper Earth environments in paleoaltimetric studies. It is highly desirable to obtain reliable thermometric, structural, and isotopic tracer data before attempting any paleoaltimetric reconstruction in such environments, as uncertainties exist about the fluid pathways and mechanisms responsible for fluid transport into the ductile crust. Maybe more importantly, it is imperative to document that the timing of meteoric water-rock interaction can be dated precisely, especially within thermally and kinematically rapidly evolving tectonic environments such as extensional detachment systems.

The orogenic displacement mechanism is a consequence of the low level of interaction between proteins and LMWE at the air-water interface. This model has been shown to work for a range of proteins with different secondary and tertiary structures and different t)q)es of LMWE (monoglycerides and phospholipids).
