The discussion concerning the classification of ore deposits has pro- ceeded on independent lines, and in a more well-balanced manner than has that of rocks. With ore deposits, as with rocks generally, genetic principles have triumphed; but the application of these principles to rocks long preceded their application to ore deposits.

Classification of mineral deposits into types using

In order to determine whether it is desirable to quantify mineral-deposit models further, a test of the ability of a probabilistic neural network to classify deposits into types based on mineralogy was conducted. Presence or absence of ore and alteration mineralogy in well-typed deposits were used to train the network. To reduce the number of minerals considered, the analyzed classifications of iron ore - izolacjeskawina.plClassification, Distribution and Uses of Ores and Ore Deposits 21 .

Mineral Ore Deposits Meaning Origin and Types Geology. In this article we will discuss about:- 1. Introduction to Ore Deposits 2. Origin of Ore Deposits 3. Types. Introduction to Ore Deposits: Minerals form chief source of all the industrial metals and non-metals. The commonly used metals like aluminum, copper, iron, lead, zinc etc. are all Origin and Classification of Ore Deposits . Charles R. KeyesOrigin and Classification of Ore Deposits. By CHARLES R. KEYES. Trans. American Inst. Mining Eng., Vol. XXX; 34 PP., 1900. The various attempts that have been made in the past to formulate a rational and at the same time a useful classification of ore deposits have met with only indifferent success. The fundamental factor in the proposed scheme by Dr. Keyes is Cut-off grade estimation - QueensMineDesignWikiPolymetallic Deposits. Polymetallic cut-off grade estimation is explained here. Mineral Classification. Cut-off grades are used to determine the point at which material becomes economically valuable. Therefore, they are necessary to define the amount of ore in a deposit. The classification of ore depends entirely on cut-off grade. Increasing EXPRESSIONS OF ORE DEPOSITS – Geology Academy19.05.2022 · A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages, i.e., the ore-host rock association (e.g., Stanton, 1972). This association broadly reflects the geological environment and processes that have formed the ore. Identified associations have been widely and successfully used in an empirical [PDF] Classification of Ore Deposits. | Semantic ScholarPROF. NIGGLI has followed his important monograph of 1920 on the function of the volatile constituents in petrology by an interesting essay on their importance in the classification of ore deposits. He adopts the view that an ore is a rock and should be studied as such, and that "ore deposition is a part problem of magmatic differentiation in its widest sense".

Ore deposit classifications attempt to group ore bodies which share certain common characteristics. Ideally, by grouping similar deposits together we can pool information and learn facts which might be useful in the discovery of similar ore deposits.
