The genetic classification of rocks and ore deposits
The discussion concerning the classification of ore deposits has proceeded 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 Ore Deposit | PDF | Igneous Rock
Geologists classify ore deposits to group those with common characteristics. This allows information sharing to aid discovery. An effective classification should be easily applied, permit categorization, and provide useful information. Three common genetic classifications are described - based on mineral/metal associations, host rock relationships, and mode …

First, simple prediction can be carried out based on visual classifiers. The data used to distinguish the types of ore deposits should be reduced to two or three dimensions. The boundaries for different types of ore deposits distinguished by ML-based methods, such as DT, KNN, and SVM, can be displayed on plots from 2D or 3D models.

A scheme of classification of hydrothermal ore deposits by chemical composition and physicochemical properties of ore-forming fluid was developed. The limiting parameters of three main types of ...
Geological Classification of Canadian Gold Deposits
Classifications of ore deposits provide essential frameworks for designing exploration strategies, evaluating prospects, and performing resource assessments of selected areas. This paper proposes a geological classification of lode gold deposits, based largely on the nature of the ore and on the geological settings of the deposits. Sixteen common types …
Mineral Deposits: Types and Geology | SpringerLink
The use of terms associated with formation temperature of ore deposits is common. Examples are epithermal (formed at less than 1500 m and temperatures between 50 and 200 °C), mesothermal (originated at intermediate depths, 1500–4500 m, and temperatures between 200 and 400 °C), and hypothermal (formed at greater than 4500 …

Classification of Sandstone-Related Uranium Deposits
Sandstone type deposits are the most common type of uranium deposits in the world. A large variety of sub-types have been defined, based either on the morphology of the deposits (e.g., tabular, roll front, etc), or on the sedimentological setting (e.g., paleovalley, paleochannel, unconformity), or on tectonic or lithologic controls (e.g., …
Classification of Ore Deposits
Modified Lindgren's classification: Modified in 1985 to conform with Lindgren's original basis for classification. Only the term "epithermal" was retained (Table 3)! Still a very popular classification! Evans (1997): classified ore deposits on the basis of their "Geologic Setting" (Table 4). The classification is very simple, but it ...
Genetic Classification of ore-forming processes
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 ...

1. Introduction. In this contribution, I will firstly attempt to define the concept of a mineral system then I suggest a classification of mineral systems, following which I will look at what is generally understood in the present context for convergent, transform and divergent plate margins; followed in turn by a rather systematised succinct overview of …

What is an ore deposit? (Chapter 1)
An ore deposit is 'what is mined'. Precise definitions of the term are based on economics rather than geology, for instance: ore is rock that may be, is hoped to be, will be, is or has been mined; and from which something of value may be (or has been) extracted. (Taylor, 1989, Ore reserves – a general overview.
