Subduction initiation at relic arcs
Although plate tectonics is well established, how a new subduction zone initiates remains controversial. Based on plate reconstruction and recent ocean drilling within the Izu-Bonin-Mariana, we advance a new geodynamic model of subduction initiation (SI). We argue that the close juxtaposition of the nascent plate boundary with relic oceanic arcs is a key factor localizing initiation of this new...
متن کاملSubduction initiation: spontaneous and induced
The sinking of lithosphere at subduction zones couples Earth’s exterior with its interior, spawns continental crust and powers a tectonic regime that is unique to our planet. In spite of its importance, it is unclear how subduction is initiated. Two general mechanisms are recognized: induced and spontaneous nucleation of subduction zones. Induced nucleation (INSZ) responds to continuing plate c...
متن کاملPlate tectonic reconstructions with continuously closing plates
We present a new algorithm for modeling a self-consistent set of global plate polygons. Each plate polygon is composed of a finite list of plate margins, all with different Euler poles. We introduce a "Continuously Closed Plate" (CCP), such that, as each margin moves independently, the plate polygon remains closed geometrically as a function of time. This method solves emerging needs in computa...
متن کاملIf Interdependent Preferences May Depend on Cognition
Economists tend to assume preferences as given (Becker and Stigler, 1977). They are the ultimate exogenous variable the basic and stable block on which economic models are built -. The exogeneity principle has been betrayed at times. Nevertheless, it is still the gate-keeper in support for the principle of parsimony of explanation, which economists have taken from Milton Friedman (1953) as thei...
متن کاملThe tectonic plates are shifting: cultural change vs. mural dyslexia.
In response to a rapidly changing healthcare marketplace, a variety of new business models have arisen, including new specialties (hospitalists), selective care (concierge medicine), and joint ventures (ambulatory surgical centers, specialty hospitals), some with hospitals and others with independent vendors. Since both hospitals and physicians are feeling the squeeze of rising expenses, burden...
