Textures of the ore minerals by Austin Burton Edwards Download PDF EPUB FB2
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.
About this book. Understanding ore textures is fundamental to understanding the genesis of an ore deposit, which in turn allows exploration and mining geologists to build their conceptual understanding of the deposits they encounter and leads to.
If you are involved in any way in hand identification of mineral exploration samples, this is a book to get.
The images are excellent. The detailed descriptions are succinct and take into account the limit of what can be done with a hand sample.
Provides logical steps to systematically examine ore textures with at most a hand lens. by: The Ore Minerals and Their Intergrowths focuses on the properties, characteristics, and reactions of ore minerals.
The book first offers information on genetic systematics of ore deposits and ore textures. Discussions focus on meteorites, magmatic, sedimentary, and metamorphic sequences, fabric properties considered from a purely geometric.

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.

the fractures. On a small scale this texture is shown in Figure 5 of Plate 9 in which all stages from incipient to nearly complete replacement of Pyrite are shown.
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.
This iron mineralization is of magnetite quartzite type enclosed by metamorphic rocks of the granulite facies.
Two main facies have been identified over the study area including the Author: Bravo Martin Mbang Bonda, Jacques Etame, Arnaud Patrice Kouske, Elie Constantin Bayiga, Gilbert Fran.
