Carbonate Eolianites from a Eustatically Influenced Ramp-Like Setting
2001Abstract Quaternary carbonate eolianites, accumulated through eolian reworking of marine sediments, occur extensively in the southern Arabian Gulf. In Abu Dhabi and Qatar these include widespread deposits belonging to the middle-late Pleistocene Ghayathi Formation, scattered coastal outcrops belonging to the Sangamonian Fuwayrit ...

Carbonate ramps and the Pleistocene-Recent depositional systems of the Arabian Gulf
Geological Society, London, Special Publications, 1998Abstract The term ramp was devised to be helpful. It was to provide an interpretative model with genetic significance for a specific category of carbonate body and one with predictive value in oil exploration. The present-day southern Arabian Gulf is commonly cited as a ramp but it fails to provide a good example. In contrast with most of its

Tuning Microstructure of Mesophase Pitch Carbon Fiber by Altering the Carbonization Ramp Rate
Advanced Engineering MaterialsThe microstructure of mesophase pitch carbon fibers (CFs) are tuned by varying ramp rates from 1 to 50 °C min−1 up to 1000 °C to study the effect of ramp rate on CFs’ microstructure, thermal and mechanical properties with the goal of offsetting the cost by decreasing cycle time.

Carbonate ramp regional seismic anlaysis in the Neuquen Basin (Argentina)
SEG Technical Program Expanded Abstracts 1997, 1997SUMMARY: Integration of data from an area of 800 km 2 , helped to localize the best facies of a carbonate Jurassic reservoir, and determine the optimal facies and structural conditions. Well data supports a detailed seismic interpretation and the detection of subtle changes produced by the target of the project. Seismic characteristics of the reservoir

Two-dimensional modeling of carbonate ramp sequences and component cycles
Bulletin (Kansas Geological Survey)Two-dimensional stratigraphic models incorporating antecedent platform topography, rotational and regional driving subsidence, sediment and water loading using an elastic beam model, water-depth-dependent sedimentation rates and rock types, lag time of the flexural response, depositional lag time following initial platform flooding, and third- to fifth-

Prestressed Carbon Strands Utilized in Repair of Football Stadium Ramp
SP-245: Case Histories and Use of FRP for Prestressing Applications, 2007This paper describes how prestressed concrete planks that use carbon fiber reinforced polymers (CFRP) tendons were used to replace badly deteriorated hollow core planks for the access ramp of the University of Wyoming football stadium. The test program for the planks is described in the paper and this is followed by the issues associated with the ...

Facies sequences on a carbonate ramp: the Carboniferous Limestone of South Wales
Sedimentology, 1986ABSTRACTDuring early Carboniferous times a major sea‐level rise led to the development of an extensive carbonate ramp over what is now South Wales. Differential subsidence and sea‐level changes resulted in distinctive facies sequences in the ramp succession and a model is offered which recognizes three distinct geomorpho‐tectonic settings; inner, mid ...

Structural complexity and fault roughness properties of carbonate relay ramps
The geometry and kinematics of small faults within relay ramps are affected by local stress perturbations due to coeval propagation of laterally overstepping normal faults with negligible separations. Independent of their stepping sense and relative fault slip rates, previous studies documented the high structural complexity of carbonate relay ramps ...Fabrizio Agosta +6 more
