12,212 datasets found for "geology"

Obtaining geochemical profiles using X-ray fluorescent (XRF) techniques has become a standard procedure in many sediment core studies. The resulting datasets are not only...

During the 2007 ANDRILL campaign in the Ross Sea, Antarctica, the AND-2A core was recovered through a stratigraphic succession spanning 1138.54 m of Neogene sedimentary rocks...

Lava, dyke and volcanic glass samples from across the northern Semail ophiolite were collected to provide references for geological mapping of the Semail volcanic units. These...

We reconstruct the provenance of aluminosilicate sediment deposited in Ulleung Basin, Japan Sea, over the last 12 Ma at Site U1430 drilled during Integrated Ocean Drilling...

The distribution patterns of calcareous dinoflagellate cysts were studied in the classic Cretaceous Tertiary (K-T) boundary section of Stevns Klint, Denmark, focusing mainly on...

Laminated sediments spanning the last 20,000 years (though not continuously) in the Shaban Deep, a brine-filled basin in the northern Red Sea, were analyzed microscopically and...

The Wüstebach catchment is located in the Eifel National Park and covers an area of 38.5 ha, with mean altitude of about 610 m. The geology is dominated by Devonian shale, which...

The Late Devonian envelops one of Earth's big five mass extinction events at the Frasnian-Famennian boundary, corresponding to the lower and upper Kellwasser black shales. The...

Lake George, New York, is the site of a new discovery of iron-manganese nodules. These nodules occur at a water depth between 21 and 36 m along a stretch of lake extending for...

The GH72-2 shipborne survey was carried out in the northwest Pacific during 31 days under the 'Basic investigations for exploration of deep sea mineral resources' program. The...

Eighty-seven manganese nodules, representing 6 different locations at depths ranging from 2400 to 7400 m, from the eastern edge of the Blake Plateau were studied. Most of the...

Among the geological discoveries of the end of the 19th century, one of the most remarkable and certainly most important from the economic point of view, is that lime phosphate...

The D'Entrecasteaux Zone (Southwest Pacific) is an arched submarine horst- and graben structure, which extends from the northern end of the New Caledonia ridge to the western...

Ferromanganese concretions from ten stations in the Barents Sea have been analysed for 24 elements. The deposits occur as discoidal and flat concretions and as coatings, in the...

Manganese nodules collected from three areas (C, F, and G) on a N-S equatorial Pacific transect at 134° W by R. V. Sonne show differences in size, morphology, surface density...

Petrological, mineralogical and chemical investigations of marine manganese nodules from the West Pacific revealed the intimate relation between the chemical and mineral...

The study of lake deposits containing iron-manganese nodules is of significant interest for the understanding of one of the continental manganese and iron concentration...

The abundance and distribution of palladium, iridium and gold has been determined in manganese nodules from widely varying locations and geological environments within the...

A gravelly sand deposit at 103 m depth on the summit region of Mount Palinuro, a seamount approximately 100 km off the Italian west coast, is made up of a mixture of manganese...

72 surface sediments associated with manganese nodules from 31 sites in the Central Pacific Ocean were obtained during CCOP/SOPAC cruises in 1980, and from the core collections...
