Highly positive Ce anomalies of hydrogenetic ferromanganese micronodules from abyssal basins in the NW and NE Pacific: Implications for REY migration and enrichment in deep-sea sediments
Huanzhen Zhang,Jun Zhou,Peng Yuan,Yanhui Dong,Wenxiao Fan,Fengyou Chu,Wansheng Xiao,Dong Liu +7 more
TL;DR: In this article , the authors selected micronodules from surface sediments of the NW Pacific inter-seamount basins and the NE Pacific Clarion-Clipperton Zone (CCZ), both distal from oceanic ridges and largely impervious to hydrothermal activities.

The Tafak manganese deposit (Dursunbey-Balıkesir, NW Turkey): implications for the submarine hydrothermal origin of İzmir-Ankara-Erzincan Neotethyan Ocean
TL;DR: In this article, the Tafak manganese deposit is mined from large-to medium-scale lenses (ca. 10 × 100 m) and interlayers with the mudstone and silicious pelagic sediments.

Plio-Pleistocene deep-sea ventilation in the eastern Pacific and potential linkages with Northern Hemisphere glaciation
Li Yi,Martín Medina-Elizalde,Liangcheng Tan,David B. Kemp,Yanzhen Li,Gunther Kletetschka,Qiang Xie,Huiqiang Yao,Huaiyu He,Chenglong Deng,James G. Ogg +10 more
TL;DR: In this paper , the authors derive a record of abyssal ventilation spanning the past 4.7 million years and evaluate its linkage to AABW formation over this period, finding that abyssal ventilation was relatively weak in the early Pliocene and persistently intensified from 3.4 million years ago onward.

Taxonomic assessment of deep-sea decapod crustaceans collected from polymetallic nodule fields of the East Pacific Ocean using an integrative approach
TL;DR: In this article , deep-sea decapod crustaceans (Crustacea: Decapoda) collected during nine research cruises to the Clarion-Clipperton Zone in the NE Pacific Ocean and the Peru Basin in the SE Pacific Ocean were studied comprehensively using an integrative taxonomic approach.

Alternative Resources for Producing Nickel Matte - Laterite Ores and Polymetallic Nodules
TL;DR: Polymetallic nodules and nickel laterite ores are composed of various valuable metals and have similar nickel concentration, which makes them ideal alternatives for industries seeking to meet the requirements of metallurgical applications.

Submarine Thermal Springs on the Galápagos Rift
John B. Corliss,Jack Dymond,Louis I. Gordon,John M. Edmond,Richard P. Von Herzen,Robert D. Ballard,Kenneth Green,David L. Williams,Arnold E. Bainbridge,Kathy Crane,Tjeerd H. van Andel +10 more
TL;DR: It is suggested that two-thirds of the heat lost from new oceanic lithosphere at the Gal�pagos Rift in the first million years may be vented from thermal springs, predominantly along the axial ridge within the rift valley.

Rare earth elements: critical resources for high technology
Abstract: The rare earth elements (REE) form the largest chemically coherent group in the periodic table. Though generally unfamiliar, the REE are essential for many hundreds of applications. The versatility and specificity of the REE has given them a level of technological, environmental, and economic importance considerably greater than might be expected from their relative obscurity. The United States once was largely self-sufficient in these critical materials, but over the past decade has become dependent upon imports (fig. 1). In 1999 and 2000, more than 90% of REE required by U.S. industry came from deposits in China. Although the 15 naturally occurring REE (table 1; fig. 2) are generally similar in their geochemical properties, their individual abundances in the Earth are by no means equal. In the continental crust and its REE ore deposits, concentrations of the most and least abundant REE typically differ by two to five orders of magnitude (fig. 3). As technological applications of REE have multiplied over the past several decades, demand for several of the less abundant (and formerly quite obscure) REE has increased dramatically. The diverse nuclear, metallurgical, chemical, catalytic, electrical, magnetic, and optical properties of the REE have led to an ever increasing variety of applications. These uses range from mundane (lighter flints, glass polishing) to high-tech (phosphors, lasers, magnets, batteries, magnetic refrigeration) to futuristic (hightemperature superconductivity, safe storage and transport of hydrogen for a post-hydrocarbon economy).

Uptake of elements from seawater by ferromanganese crusts: solid-phase associations and seawater speciation
Andrea Koschinsky,James R. Hein +1 more
TL;DR: In this paper, the authors proposed a simple sorption model related to the inorganic speciation of the elements in seawater, as has been proposed in earlier models, in order to determine the host phases of 40 elements.

Sequential leaching of marine ferromanganese precipitates: Genetic implications
Andrea Koschinsky,Peter Halbach +1 more
TL;DR: In this paper, the results of leaching experiments were carried out on twentyone hydrogenetic crust samples from different locations in the central Pacific and the results were compared with four crust and nodule samples of different genetic origin.
