  Diamonds are rare gemstones commercially mined in kimberlite, lamproite and placer deposits. Most originate from the earth's mantle, but the rare gemstone can be found in nature using sound prospecting methods. The author (the GemHunter) found many kimberlites and diamonds over the years as well as a variety of other gemstones. 1 1.

Rare Earth Minerals presents a current overview of this geologically and industrially important group of minerals. It presents a wide variety of formats, crystal structures, petrographic descriptions, analytical data and numerous illustrations from outcrop photos to SEM pictures and crystallographic models.

The text then tackles origin and nature of ore deposits book accumulation in limnic sediments, trace metals in fresh waters, nature and origin of Archaean strata-bound volcanic associated nickel-iron-copper sulphide deposits, and the significance of pyritic black shales in the genesis of Archean nickel sulphide deposits.

Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.

Kutcherov. Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth's crust.

Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate opes: α- β-rhombohedral, β-tetragonal (and more). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel —98% of the mined iron ore. According to shape fea tures, ore deposits can be classified into three group s as follows: i. Isometrical group: stock, nests, irr egular shapes but their dimensions in space do not differ.

Classification of ore deposits However, genetic classifications are very dangerous, as they assume that we know the origin of the ore deposit, which, in many cases, we don’t. divided into orthomagmatic, pneumatolytic to pegmatitic, and hydrothermal deposits.

Mineral deposit - Mineral deposit - Hydrothermal solution: Hydrothermal mineral deposits are those in which hot water serves as a concentrating, transporting, and depositing agent.

They are the most numerous of all classes of deposit. Hydrothermal deposits are never formed from pure water, because pure water is a poor solvent of most ore minerals. GOLD: History and Genesis of Deposits is the product of an effort by the Society of Economic Geologists to publish materials that will expand knowl edge concerning timely, specific topics important to the study of economic geology and to economic geologists.

The book first offers information on intracrustal and subcrustal. About this book. From the first attempts to understand the origin of giant iron ore deposits, numerous false assumptions have been used as the basis of genesis models that have become standard and unquestioned, with later research generally seeking to find evidence supporting the existing models and ignoring contrary evidence.

Regional Studies and Specific Deposits deals with regional studies of strata-bound and stratiform ore deposits. Topics covered include the geological association between coal and metallic ores; the genesis of iron ores in banded iron-formation (BIF) by supergene and supergene-metamorphic processes; mineral zoning in sediment-hosted copper deposits; and the formation of gossans.

Considering this, GEUS focusses on the study of basin architecture and evolution as a key contribution towards exploration, and we are working on assessing occurrence favourability, predicting locations for mineralisation, and understanding the origin of sediment-hosted ore deposits.

THE origin of early Precambrian gold-uranium ore deposits has indeed been a controversial issue. But, as I stated explicitly in my book, I have become convinced that the features acquired by hydrothermal processes are due to younger alterations.

These deposits are placers originally. The hydrothermal alterations have been important in enriching the original placers.
