The goal of this project is to use ArcGIS to create models based on characteristic features that may be useful as indicators of the presence of ore deposits in West Texas, and to use these models to perform a suitability analysis within the region to predict the potential locations of other such deposits that are yet to be discovered.
An ore body model has three distinct components, viz. (i) the physical geometry of the geologic units that formed and host the ore body; (ii) the attribute characterisation in terms of assays and geomechanical properties of all materials to be mined; and (iii) the value model in terms of economic mining of the ore .
Not all skarns have economic mineralisation; skarns which contain ore are called skarn deposits. In most large skarn deposits, skarn and ore minerals result from the same hydrothermal system even though there may be significant differences in the time/space distribution of these minerals on a .
have identified 1,124 individual podiform chromite deposits, based on a 100meter spatial rule, and have compiled them in a database. Of these, 619 deposits have been used to create three new grade and tonnage models for podiform chromite deposits. The major podiform chromite model .
May 19, 2015· SEDEX ore deposits are formed due to concurrent release of orebearing hydrothermal fluids into aqueous reservoir mainly ocean, resulting in the precipitation of stratiform zinclead sulfide ore in a marine basin environment. The stratification may be obscured due to post depositional deformation and remobilization.
Geologic modelling, geological modelling or geomodelling is the applied science of creating computerized representations of portions of the Earth''s crust based on geophysical and geological observations made on and below the Earth surface. A geomodel is the numerical equivalent of a threedimensional geological map complemented by a description of physical quantities in the domain of .
This disconnect between wellestablished ore deposit models from the actual 3D geometry of ore deposit geology was the rationale for the development of a fast, threedimensional, and structurally focused method of implicit geological modelling (Cowan et al., 2002). Used in conjunction with structural concepts, implicit modelling methods
porphyry copper deposits were the first type of metallic mineral deposit to be exploited by largescale, bulk tonnage, open pit mining methods. Economies of scale and advances in technology have made it possible to profitably mine these deposits despite their relatively low ore grades.
Thus we summarize the state of knowledge regarding ore deposit models, and we call them "mineral deposit models" with the hope that what we have learned about large and highgrade metal concentrations will help us sort out all mineral occurrences to identify their true character and, we hope, to recognize which have potential to constitute ore ...

of the deposit, geochemical anomalies, and important orecontrolling conditions. Lang et al. (2017) established a comprehensive information prospecting model with the aim of searching for Cu–Au ore deposits and expanding the quantity of resources. To date there are no ore prospecting models to guide prospecting for Te deposits.
A polymetallic replacement deposit is an orebody of metallic minerals formed by the replacement of sedimentary, usually carbonate rock, by metalbearing solutions in the vicinity of igneous intrusions. When the ore forms a blanketlike body along the bedding plane of the rock, it is commonly called a manto ore ore geometries are chimneys and veins.

Sedimentary deposits are formed through the erosion, transportation, and redeposition of minerals that can survive the rigors of transportation. The most common is silica, which forms a number of materials, including silica sand, sand and gravel, and flint. The precursor is igneous quartz (, in granite), and then the sedimentary deposit may undergo metamorphism and recementing to produce ...

Marblehosted ruby deposits represent the most important source of colored gemstones from Central and South East Asia. These deposits are located in the Himalayan mountain belt which developed during Tertiary collision of the Indian plate northward into the Eurasian plate.
Oct 20, 2012· yes, quite so! but if english is your native tongue, there is a significant difference between ''good'' (beneficial) ''goods'' (tradeworthy products) as you point out. also ''deposit'' can be interpreted in 2 ways. if you just added an ''s'' to ''good'' also to the deposit itself, it would make it .
