Rapid sedimentation by fine-grained sediments on the upper slope of the New Jersey margin has generated nearly lithostatic fluid pressures. We use measured porosity from ODP Site 1073 to predict the in situ fluid pressures. We then simulate the pressure history with one-dimensional and two-dimensional sedimentation-compaction models. Two-dimensional models simulate a compaction-driven flow fiel...

this research was done in order to determine the basic criteria for “tehran oil refinery effluemt treatmentunit” to prove the feasibility of the application of powdered activated carbon in aeration zone of activated sludge system. the main stages of this research included: determination of qualitative and quantitative characteristics of raw wastewater preparation of two pilot scale units of act...

This study contributes to our understanding of the evolution Hal?lar Cu-Pb (±Zn) mineralization (NW Turkey) based on mineralogical and geochemical results sulfur isotope data. The area represents local with some Zn brecciated-stockwork vein type along NE–SW fault gouge zone at lower boundary Sakarkaya Düztarla granitoid rocks. Two main zones, consisting sericite–quartz–chlorite ± kaolinite pyri...

It is a fundamental task to monitor the topography and understand changes of intertidal zone for rational utilization sustainable development. A new method proposed identifying terrain zone, using ICESat-2 data replace large amount on-site observation data, thereby reducing costs improving efficiency. Based on pre-experiments correlation analysis, time phase index, water transparency index susp...

Rock-walled archaeological features are notoriously hard to date, largely because of the absence of suitable organic material for radiocarbon dating. This study demonstrates the efficacy of dating clam garden wall construction using optical dating, and uses optical ages to determine how sedimentation rates in the intertidal zone are affected by clam garden construction. Clam gardens are rock-wa...

Inversion of NASA Operation IceBridge airborne gravity over the Abbot Ice Shelf in West Antarctica for subice bathymetry defines an extensional terrain made up of east-west trending rift basins formed during the early stages of Antarctica/Zealandia rifting. Extension is minor, as rifting jumped north of Thurston Island early in the rifting process. The Amundsen Sea Embayment continental shelf w...

Bulk X-ray mineralogy of 47 hemipelagic mud and clay samples from the Blake Outer Ridge has revealed that the sediments contain low magnesian calcite, calcian dolomite, ferroan dolomite, and magnesian siderite. Dolomite and siderite are authigenic and occur as rhombohedrons scattered through the sediments, whereas calcite is mostly biogenic. Pliocene dolomitic lenses are made up of interlocking...
