The geology, geochronology, structure and geochemistry of the Wild Rogue Wilderness remnant of the Coast Range ophiolite, southwest Oregon: Implications for the magmatic and tectonic evolution of the Coast Range ophiolite

The Wild Rogue Wilderness ophiolite (WRWO) has been correlated with the Coast Range ophiolite (CRO) and overlying Great Valley Sequence in California. The WRWO occurs on the east limb of a large Cretaceous syncline within a folded thrust sheet. The basement units strike NE, are subvertical and fault bounded and include from east to west: (1) a sheeted dike complex having gabbro screens; (2) a ductily, but heterogeneously deformed metatonalite containing abundant mylonites; (3) a heterogeneously deformed metagabbro having a relic magmatic foliation overprinted by solid-state deformation at amphibolite facies and lower grade conditions; (4) a 0.5–0.9 km wide, high-strain zone consisting of mafic and silicic ultramylonites and mylonites; (5) undeformed pillow basalts cut by mafic and silicic dikes; (6) quartz gabbro to tonalite (Half Moon Bar diorite); (7) poorly exposed metavolcanic rocks, including at least some volcaniclastics in the uppermost section of this unit. The following events have been identified in the Wild Rogue Wilderness: (1) preophiolite deformation and (regional?) amphibolite facies metamorphism (unit 3; ∼171 Ma); (2) formation of the ophiolite, related normal faulting and subseafloor hydrothermal alteration (units 1, 2, and 5; ∼164 Ma); (3) Post-ophiolite arc-related magmatism (units 6 and 7; 153–160 Ma); and (4) Nevadan-age ductile deformation (unit 4 and mylonites in units 2 and 3; ∼149 Ma). The trace-element analysis indicates that the WRWO consists of rocks having magmatic affinities to normal mid-ocean ridge basalt island-arc tholeiite, calc-alkaline basalt and boninite. Compositional variations within units and between units cannot be explained with differences in the degree of partial melting and/or fractionation. A highly heterogeneous source is inferred, which was probably variably depleted by previous melting and variably re-enriched with a subduction component. The evolution of the WRWO is similar to that of the CRO and the Josephine ophiolite, which is consistent with previously proposed models that invoke rifting of the volcanic arc built on western N. America. The geochemical diversity of the WRWO is indicative of formation in a fore-arc or intra-arc setting similar to that of the Miocene Tonga are, SW Pacific. Rift-propagation and melting of heterogeneous, inherited mantle may have played an important role in the magmatic evolution of the WRWO

The Microfossils in a Pre-Kansan Peat Deposit near Belle Plaine, Iowa

In 1937 a portion of U. S. Highway 30 near Belle Plaine, Iowa was re-routed, resulting in extensive cuts through the Nebraskan and Kansan glacial drifts. Several exposures of Aftonian peat were found between the two drifts. The locality at which collections were made is 4.9 miles west of Tama county line on U. S. Highway 30. The peat was prepared for microscopic study and one hundred and fifty plant microfossils were counted. Percentages were computed for each of the levels and the percentages show the abundance of the microfossils at each level. The distribution of the tree-pollens in the study suggests a change from a cold climate at the upper contact to a warmer one at the two and four inch levels, and finally a return to the cold climate. This would seem to correlate with the retreat of the Nebraskan and the invasion of the Kansan ice sheets

Enterprise Modeling in the context of Enterprise Engineering: State of the art and outlook

[EN] Enterprise Modeling is a central activity in Enterprise Engineering and can facilitate Production Management activities. This state-of-the-art paper first recalls definitions and fundamental principles of enterprise modelling, which goes far beyond process modeling. The CIMOSA modeling framework, which is based on an event-driven process-based modeling language suitable for enterprise system analysis and model enactment, is used as a reference conceptual framework because of its generality. Next, the focus is on new features of enterprise modeling languages including risk, value, competency modeling and service orientation. Extensions for modeling collaborative aspects of networked organizations are suggested as research outlook. Major approaches used in enterprise modeling are recalled before concluding.Vernadat, F.

Seven New Species of Unassigned Plant Microfossils from the Des Moines Series of Iowa

The coals of the Des Moines Series of Iowa contain an abundance of unassigned plant microfossils and in this report a few of the more diagnostic new types are described. At the present time little can be stated concerning the vertical distribution of these microfossils but preliminary work has shown that some are definitely restricted to certain strata and should become useful horizon markers as more information is accumulated. In 1940, Wilson and Coe described eleven new species of unassigned plant microfossils from the Des Moines Series of Iowa. Several of these have since been transferred to other genera by Schopf, Wilson, and Bentall (1944). The specimens that constitute the types of species described here are in the collection of the senior author. The authors wish to express their appreciation to Dr. Theodor Just, University of Notre Dame, for checking the construction of the new specific names used in this paper

Application of PLM processes to respond to mechanical SMEs needs

International audiencePLM is today a reality for mechanical SMEs. Some companies implement PLM systems very well but others have more difficulties. This paper aims to explain why some SMEs do not success to integrated PLM systems analyzing the needs of mechanical SMEs, the processes to implement to respond to those needs and the actual PLM software functionalities. The proposition of a typology of those companies and the responses of those needs by PLM processes will be explain through the applications of a demonstrator applying appropriate generic data model and modelling framework
