Physical Controls Of Mud Deposition In A Backbarrier System, Spiekeroog Island German Wadden Sea, N. Nyandwi Dec 1995

Physical Controls Of Mud Deposition In A Backbarrier System, Spiekeroog Island German Wadden Sea, N. Nyandwi

Tanzania Journal of Science

The areal distribution of the mean grain size of the sand fraction indicates presence of a shore-normal energy gradient with a shoreward fining from a mean grain size of 2.0 phi (0.25 mm) on Spiekeroog island to 3.5 phi (0.09) mm) near the dyke which forms the landward boundary of the tidal flat. This energy gradient is also reflected by the shoreward increase in the mud content of the sediment. Until recently, the relation of the mud distribution to the energy level variation in the Wadden Sea was not clearly known. Purely mud zones (˃ 50% mud) occur in the …


The Mozambique Of Eastern Tanzania: Evidence For Pan-African Reactivation Of Early Proterozoic Usagaran Basement, M.A.H. Maboko Dec 1995

The Mozambique Of Eastern Tanzania: Evidence For Pan-African Reactivation Of Early Proterozoic Usagaran Basement, M.A.H. Maboko

Tanzania Journal of Science

The high grade metamorphic rocks of Eastern Tanzania belong to two distinct tectonothermal belts; the early Proterozoic Usagaran Belt and the late Proterozoic (Pan–African) Mozambique Belt. Rocks of the Usagaran Belt, which locally sow evidence of eclogite facies metamorphism, experienced peak metamorphic conditions at ⁓ 2000 Ma. Tectonic activity in the Usagaran added at ⁓ 1800 Ma with the emplacement of post-organic granites. In contrast, the Mozambique Belt, which is characterized by extensive granulite complexes, experienced peak metamorphic conditions at about 700 Ma. Due to the similarity of both structural trends and metamorphic grade, the boundary between the two belts …


Palynostratigraphy Of Cretaceous Sediments, Rufiji Basin, Tanzania, E. Msaky Dec 1995

Palynostratigraphy Of Cretaceous Sediments, Rufiji Basin, Tanzania, E. Msaky

Tanzania Journal of Science

Cretaceous sediments from Luhio - 1 borehole drilled in the Rufiji basin yielded a palynomorph assemblage of spromorphs and dinoflagellate cyst species. The age of the sediments penetrated ranges from Early Cretaceous (Albian) to Late Cretaceous (Senonian). The Early Cretaceous is characterized by presence of the following dinocyst key species: Litosphaeridium arundum, Dinopterygium tuberculatum, Florentinia Cooksoniae, Systematophora cretacea and Oligosphaeridium pulcherrimum. The Late Cretaceous (Senonian) is characterized by the presence of the following dinocyst key species: Cannosphaeropsis utinensis, Dionogymnium pustulicostatum, Florentinia ferox, Odontochitina porifera, Odontochitina operculata, Xenascus sarjeantii and Xiphophoridium asteriforme …

A Wellhead Protection Study Of A Small Agricultural Community In Glaciated Terrain, As A Model For Wellhead Protection Efforts By Similar Communities, Cole Kevan Lovett Jun 1995

A Wellhead Protection Study Of A Small Agricultural Community In Glaciated Terrain, As A Model For Wellhead Protection Efforts By Similar Communities, Cole Kevan Lovett

Dissertations

The purpose of this study was to create a wellhead protection approach for a small town in a rural watershed that could be used by other, similar, communities.

Lacustrine clay and melt-out till interbedded in outwash sands and fine gravel, separate an unconfined aquifer from a deeper aquifer. The lower aquifer was determined to be semiconfined due to (a) high vertical conductivity, (b) lack of continuity in the clay/till, (c) absence of significant seasonal water level changes, and (d) tritium levels above 1-2 tritium units in deep wells.

Tritium level falls and water age rises along flowpaths. A low-high-low pattern …
