These processes fall into certain natural groups and sub-groups according to the way in which they operate on and modify the rocks of the earth's crust. The corresponding scheme for rocks may claim to be scientific. 1.

The use of intrinsic data and other non-genetic data in petrography finds its place in the definitions of rock types, but these definitions should be controlled by genetic and geological considerations. Copyright Geological Journal of China Universities, All Rights Reserved. On the basis of the preceding study, a new genetic classification scheme is tentatively put forward, in which 5 types and 13 subtypes are discriminated, and representative ore deposits examples are given for each type and subtype. Blockchain + AI + Crypto Economics Are We Creating a Code Tsunami? Like www.HelpWriting.net ? It is based on a well-defined genetic method. The existing genetic mineral deposit classifications has developed and embraced the genetic classification of ore-forming processes in accordance with system theory, structured taxons revealing the nature of the processes and the basis- information source of these processes.

Such a scheme of division into endogenetic and exogenetic processes is adopted in this paper, and the subdivision is made in accordance with the geological action of the processes concerned. The studies of recent years in ore genesis have largely extended the significance of solutions of deep-seated origin in connexion with ore deposition. Did u try to use external powers for studying? Agreement NNX16AC86A, IOP Conference Series: Earth and Environmental Science, Is ADS down? The geological mineralization types within ore formations and subformations are included in the genetic classification of ore-forming processes. Three subtypes are included: the metamorphic recrystallization subtype, the components recombination by metamorphic chemical reactions subtype and the metamorphic hydrothermal ore deposits subtype; (3)Metamorphic ore deposits of local metamorphism. An appeal to historical considerations likewise shows that the requirements of science, as regards the classification of rocks, seem to lie in the direction of a scheme based on what may be called genetic-geological principles. The SlideShare family just got bigger. A consideration of fundamental principles shows that petrography has its scientific basis in dynamical geology, and that any genetic scheme of classification for rocks should also be a geological scheme.

Having decided on a definite geological grouping of formative processes in this way, the grouping of rocks with reference to the processes that have determined their type characteristics becomes possible, the rock-groups corresponding to process-groups. There are, nevertheless, certain vein types which are known to arise from solutions of surface origin ; and although the criteria for determining the origin of vein deposits are not fully established for all types, it seems permissible to adopt a genetic scheme in which processes are grouped geodynamically in two broad groups according to their internal or external origin in relation to the earth's crust. Abstract: Mineralogical Magazine; July 1914 v. 17; no. (1)Metamorphosed ore deposits, which are subdivided into five subtypes: the metamorphosed banded iron formation (BIF) sedimentary subtype, the metamorphosed BIF volcanosedimentary subtype, the other metamorphosed sedimentaryvolcanosedimentary formation subtype, the metamorphosed igneous alteration ore deposits subtype and the metamorphosed spilitekeratophyric volcanoeruptive sedimentary ore deposits subtype; (2) Metamorphic ore deposits of regional metamorphism. 4.

The genetic classification of rocks and economic mineral deposits is thus essentially a classification of formative processes, and a correlation of these processes with the rock types the intrinsic characteristics of which they have developed. 79; p. 55-85; DOI: 10.1180/minmag.1914.017.79.02 Economic geology - Genetic classification of ores, Learn faster and smarter from top experts, Download to take your learnings offline and on the go.

The base involved the developed model system of ore mineralization- ore formations (geological formations with syngenetic mineralization) within poly-component and mono-component subformations; for convergent mineralization- geological types of deposits.

The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative The fact that uncertainty exists as to the nature of certain processes and the origin of certain types should be no bar to the adoption of such a scheme up to the limits of known facts and well-established theories, since it is one that will adapt itself to the progress of petrology. See our Privacy Policy and User Agreement for details. This paper discusses the definition of the metamorphic ore deposits. 0 / This attitude on their part made possible, at a comparatively early date, an approximation to a sound genetic-geological scheme of grouping for rocks.

A scientific classification in accordance with these principles presupposes the possibility of a geological classification of formative agents and processes.

Discussion on Genetic Classification of Metamorphic Ore Deposits[J]. The absence of a genetic classification of ore-forming processes is the result of a rather slow-paced accumulation of knowledge in ore-forming processes, which, in its turn, could be explained by objective conditions such as the fact that during the last few decades the genetic classification included only the description of mineral deposits. If you continue browsing the site, you agree to the use of cookies on this website. This, in its turn, makes it possible to forecast the functions and provide a regular transition into the geological-genetic classification of ore-forming processes in accordance to above-mentioned matrix-structure, and, simultaneously, further the development of the existing geological- genetic theory of ore formation. Two subtypes are included: the migmatiticmetasomatic subtype and the later stage migmatitichydrothermal subtype.

Ph.D. Petrologists have for the sake of convenience, but with lack of wisdom, refused to regard most economic mineral deposits as rocks. Dr. Abdel Monem Soltan Three subtypes are determined: the skarn ore deposits of contactmetasomatism subtype, the local thermal contactmetamorphic subtype and the local dynamometamorphic subtype;(4) Metamorphosed sedimentaryvolcanosedimentary ore deposits superimposed and transformed by metamorphic hydrothermal solutions; (5) Ore deposits by migmatism.
