The classification of the ore bearing rock type is challenging due to the fact that textures and mineral assemblage are obscured by post-magmatic alteration. In addition, the alteration causes fine and intricate intergrowth of the ore minerals with associated gangue. separate them from other minerals depends on mineral dep ortment and texture.

When the same minerals are found among both the phenocrysts and the groundmass, it is safe to ascribe this texture to two-stage cooling, with the fine-grained groundmass produced by a sudden increase in by: By Jesse Stay, Thomas Stay. Ores and minerals are an important part of Minecraft, and are often considered one of the main resources in the game. Typically, these supplies are acquired through the act of mining, which is one of the most common ways of harvesting ls that you find or mine such as coal, emeralds, iron, and diamonds can be crafted into blocks. Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of ore-bearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore.. SedEx deposits are the most important source of lead, zinc and barite, a major contributor of silver, copper, gold, bismuth and tungsten.

Ore microscopy involves not only the identification of individual mineral grains but also the interpretation of ore mineral textures, that is, the relationship between grains. Ore mineral textures may provide information on: Process of initial ore deposition. Texture and microstructure modeling (e.g. VPSC, FF-VPSC, ELLE, etc.) are quickly evolving to face paramount challenges on polycrystal plasticity.

This is an excellent resource for the exploration and field geologist. It contains clear logical steps in deciphering ore textures at the hand-sample and microscopic level together with plenty of photographs.

A very useful book highly recommended for any geologist involved in the mineral /5(9). Usually dispatched within 3 to 5 business days. Understanding ore textures is fundamental to unraveling the genesis of an ore deposit, which in turn allows exploration and mining geologists to build their conceptual models of the deposits they encounter and leads to more successful exploration and exploitation.

Textures of Ore Deposits Importance of studying textures Textural identification and interpretation for ore deposits and associated gangue minerals are tools necessary for understanding the processes involved in the genesis of these deposits, which in turn is very important for prospecting for other similar economic Size: 1MB.

Textures of economic ore deposits I- Magmatic ores: 1- Cumulus textures: result from the settling of an ore deposit from a crystallizing magma. The most common example is chromite which occurs as a cumulus phase relative to pyroxenes.

2- Intergranular or intercumulus textures: where the ore mineral occurs as an intergranular anhedral phase. Most ore deposits are mined for the exploitation of metals. A metal is any chemical element (or elements in an alloy) having a characteristic luster, is opaque, and is a good conduc tor for heat and electricity.

Approx imately 80 of our chemical elements are metals. Heavy metals have a density $ 5 g/ Size: 46KB. We would like to show you a description here but the site won’t allow more.

The dependence ofthe properties, textures, and associations of the minerals on their crystal chemistry, thermochemistry, and phase relations is an aspect of modern studies of ore minerals that is particularly emphasized.

Although there are a large number of mineral deposits, this article takes into consideration only a few general themes as type examples. The mineral deposits outlined and discussed are hydrothermal, syngenetic, epigenetic (vein, porphyry), skarn, magmatic, and Size: KB.

Metamorphic Textures provides definitions, descriptions and illustrations of metamorphic textures, as well as the fundamental processes involved in textural development. This book is composed of 11 chapters and begins with a presentation of the metamorphic processes and the production of metamorphic minerals.

Tis text has resulted from some forty years of experience during which the author has puzzled over the meaning of ore textures.

Te learning process has been slow and is still incomplete. Te bemusement began directly upon leaving the academic confnes, which in retrospect lef one keen young geologist very ill-equipped to interpret the mineralising process.

The term texture as used here refers to the smaller features of ores which are dependent on the size, forms, and arrangement of the component minerals and in some cases upon such features as mineral cleavage, mineral parting, mineral contacts, and minor fracturing.

These features can be observed in hand specimens either with the unaided eye or with the microscope. The peculiarities of ore textures observed in polished handspecimens and polished sections are observed using examples of three deposits of the Soviet Union and Cuba.

Each of the above mentioned three types of deposits have distinctly different textures of ores. These textures characterize depositional conditions of the main ore mineral Cited by: 5.

On a larger scale similar phenomena are shown in Figure 6 of Plate 9. None of the numerous pyrite areas are in contact with each other. This study presents the ore texture, mineralogy and whole rock geochemistry of iron occurrence from the Edea North area located at the upper limit of the Nyong Unit, part of the Congo craton.
