Controls on authigenic carbonate precipitation at cold seeps along the convergent margin off Costa Rica
[1] Five sediment cores from cold seeps at the forearc off Costa Rica were used to explore the relationship between fluid advection, dissolved Ca concentrations in upward migrating fluids, and authigenic CaCO3 precipitation. A numerical transport‐reaction model was used to determine rates of anaerobic oxidation of methane (AOM), CaCO3 precipitation, and benthic fluxes of solutes. Production of ...
متن کاملFluid flow paths in the Middle America Trench and Costa Rica margin
The hydrology of the subducting plate and its dewatering behavior through the shallow subduction zone is linked to the structure and deformation of the forearc prism, the nature of the seismogenic zone, the composition of seawater for selected elements, and the composition of the residual slab subducted to depths of magma generation at the volcanic arc. Two locally independent systems of fluid ...
متن کاملNeural network interpretation of LWD data (ODP Leg 170) con¢rms complete sediment subduction at the Costa Rica convergent margin
The internal structure of a convergent plate boundary was the focus of ODP Leg 170 in 1996 at the subduction zone off Costa Rica. Although the structure of the subduction zone is rather well known from seismic surveys, prior to drilling of ODP Leg 170 it was a matter of discussion whether it is accretionary or non-accretionary. With a neural network approach, we confirm the evidence gained duri...
متن کاملThe Case of Costa Rica
In this paper, I discuss the reasons for Costa Rica’s economic performance over the last quarter of a century. Three complementary sets of policies (investments in human capital, careful stabilization, and an intelligent and aggressive integration into the world economy) explain the successful trends, and can be thought of—at least in hindsight—as a development strategy. While fruitful, this st...
متن کاملThe dystrophinopathies in Costa Rica.
A five-years long study aiming to describe the basic genetic epidemiology of the dystrophinopathies in Costa Rica recruited 31 patients with clinical symptoms of DMD/BMD at the National Children's Hospital (HNN). This center is the obligate reference hospital of the national health system for genetic diseases, however, the geographic origin of the patients, a low percentage of deletions and a h...
