Two episodes of monazite crystallization during metamorphism and crustal melting in the Everest region of the Nepalese Himalaya
New monazite U-Pb geochronological data from the Everest region suggest that ∼20–25 m.y. elapsed between the initial India-Asia collision and kyanite-sillimanite–grade metamorphism. Our resultsExpand

The Ecology of Freshwater Tidal Wetlands
ties of less than one percent, but insufficient flow to dampen upstream tidal movement. Odum et al. (1979) conservatively estimate that there are 500,0001,000,000 ha of freshwater tidal wetlandsExpand

A mechanism for the accumulation and retention of heavy metals in tidal freshwater marshes of the upper Delaware River estuary
A mechanism for the accumulation and retention of heavy metals in tidal freshwater marshes is proposed. Although metals are incorporated into tidal freshwater marsh substrates through the year byExpand

SEED BANK OF A FRESHWATER TIDAL WETLAND: TURNOVER AND RELATIONSHIP TO VEGETATION CHANGE
Depletion during spring germination (turnover), longevity, and successional relationships were studied at High Marsh (HM), Cattail (CT), and Shrub Forest (SF) sites in a freshwater tidal wetland overExpand

The role of Delaware River freshwater tidal wetlands in the retention of nutrients and heavy metals
Tidal cycle budgets for June, July, August, September, and November 1979 showed that inorganic N was imported to the wetland from the Delaware River early in the growing season and exported late inExpand
