(2006)We present a detailed study of the co-diagenesis of Fe and P in hydrothermal plume fallout sediments from ?19?S on the southern East Pacific Rise. Three distal sediment cores from 340-1130 km from the ridge crest, collected ...
-
(2006)Helium isotopes have been measured in samples of two ferromanganese crusts (VA13/2 and CD29-2) from the central Pacific Ocean. With the exception of the deepest part of crust CD29-2 the data can be explained by a mixture ...

IS AMINO ACID CHRONOLOGY APPLICABLE TO THE ESTIMATION OF THE GEOLOGICAL AGE OF SILICEOUS SEDIMENTS? (2002)There are few conventional dating methods that can be used to estimate the geological age of siliceous sediments on the order of 104-105 yr. In contrast, methods such as δ18O are available for dating carbonate-containing ...
-
(2003)We analyzed normal saturated paraffins (n-paraffins) in 70 surface sediments in the northwest Pacific to examine the spatial distribution of organic materials. All sediments show bimodal n-paraffin abundance patterns against ...
-
(2006)Tree-ring based mass balance reconstructions developed for Peyto Glacier, Alberta, Canada are compared with measured conditions in the Pacific Ocean over the last century and, using reconstructions of Pacific climate ...
-
(2002)The inorganic silicate fraction extracted from bulk pelagic sediments from the North Pacific Ocean is eolian dust. It monitors the composition of continental crust exposed to erosion in Asia. 176Lu/177Hf ratios of modern ...
-
(2003)The internal microstructure of a ferromanganese nodule (#2392, from 154°37.52'W, 9°37.56'N, at water depth 5194 m) was examined in detail on polished sections, and radiometrically dated (230Thex/232Th) along a high-resolution ...
-
(2001)This paper presents a revised chemical purification method of Hf for the measurement of Hf isotope ratios of Fe-Mn crusts on a new generation of double focusing multiple collector plasma source mass spectrometer (MC-ICP-MS).By ...
-
(2006)By the synthesis study for three central Pacific ferromanganese crusts (hereinafter for short as crusts) of their biostratigraphy, structure and element geochemistry on the section along their growth directions, it was ...
-
(2006)QP factor at the top of the inner core (IC) is derived using the amplitude spectral ratio (PKPbc versus PKPdf) method applied to the waveforms of suitable, strong (magnitude > 6.0) intermediate depth and deep (h > 150 km) ...
-
(2006)Новые результаты статистического анализа распределения глубин Тихого океана на основе цифровых данных ЕТОРО 2' представлены в форме батиграфических и батиметрических кривых и поверхностей с интервалом 100 м по глубине для ...
-
(1996)Two dredging and profiling traverses were conducted across the Kermadec arc system at 30-33˚S. The system comprises, from the west, the Colville Ridge (remnant arc), Havre Trough (active backarc basin), Kermadec Ridge ...

НОВЫЕ ГЕОЛОГИЧЕСКИЕ И ПАЛЕОНТОЛОГИЧЕСКИЕ ДАННЫЕ ПО ГАЙОТУ ФЕДОРОВА (МАГЕЛЛАНОВЫ ГОРЫ, ТИХИЙ ОКЕАН) (2006)В результате экспедиционных исследований, проведенных ГКЦ "Южморгеология" в 2001-2004 гг. в Тихом океане на НИС "Геленджик", получены новые материалы, позволившие установить особенности геоморфологического строения гайота ...
-
(2005)По материалам полигонных исследований приводятся новые данные по литологии и стратиграфии кайнозойских отложений зоны трансформного разлома Кларион (Тихий океан). Установлено, что на приподнятых и опущенных блоках одноименной ...
-
(2006)Результаты геологического изучения абиссальных участков по периферии Магеллановых гор показали, что кобальтбогатые железомарганцевые конкреции (Со-ЖМК) образуют высокопродуктивные залежи (с весовой плотностью 20 кг/м2 и ...
