The high natural abundance of nickel, copper, cobalt, zinc, iron, and manganese in ferromanganese nodules has promoted research into their use as a rare metal resource. The Clarion–Clipperton zone in the northeastern Pacific Ocean has been observed as an area containing the highest concentration of resource-grade nodules. [4]
Main ore minerals in SEDEX deposits are fine-grained sphalerite and galena, chalcopyrite is significant in some deposits; silver-bearing sulfosalts are frequent minor constituents; pyrite is always present and can be a minor component or the dominant sulfide, as it is the case in massive sulfide bodies; barite content is common to absent ...
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
Project Kaisei (from 海星, kaisei, "ocean planet" in Japanese [1]) is a scientific and commercial mission to study and clean up the Great Pacific Garbage Patch, a large body of floating plastic and marine debris trapped in the Pacific Ocean by the currents of the North Pacific Gyre. [2]
Economic metals In island arc settings where the host plutons are typically andesitic in composition, the elements of economic interest are mainly copper and gold. In contrast, those that occur in continental orogenic belts are typically rhyolitic in composition and carry copper, molybdenum and gold, and in some cases tin and/or tungsten .
The term diagenesis, literally meaning "across generation", [3] is extensively used in geology. However, this term has filtered into the field of anthropology, archaeology and paleontology to describe the changes and alterations that take place on skeletal (biological) material. Specifically, diagenesis "is the cumulative physical, chemical ...
The project was based off the coast of Papua New Guinea (PNG), near New Ireland province. The project was a joint venture between Papua New Guinea and Nautilus Minerals Inc. Nautilus Minerals held a 70% stake and Papua New Guinea purchased a 30% stake in 2011. [45] PNG's economy relies upon the mining industry, which produces around 30–35% of ...
A newer commercial use for pyrite is as the cathode material in Energizer brand non-rechargeable lithium metal batteries. [20] Pyrite is a semiconductor material with a band gap of 0.95 eV. [21] Pure pyrite is naturally n-type, in both crystal and thin-film forms, potentially due to sulfur vacancies in the pyrite crystal structure acting as n ...
