A grade-tonnage deposit model represents the distribution and the statistical relationships of the pre-production tonnages and the average grades of the commodities of well-explored deposits of a particular mineral deposit type. The purpose of constructing such a model is to further define some of the more common mineral deposit types that occur in Ontario. This report documents 16 such grade-tonnage deposit models, representing Ontario deposit types for which there are no available or adequate models from the United States Geological Survey. The deposit types include: lode gold, Archean volcanic-associated massive sulphide, volcanic-hosted copper, paleoplacer uranium, stratiform chromite, Precambrian porphyry, lithium and uranium pegmatites, talc, magnesite, Cobalt type silver-sulpharsenide vein, Canadian komatiite-hosted nickel-copper, and mafic intrusion-hosted titanium-iron-vanadium-phosphorus.

Geological Classification Of Canadian Gold Deposits written by Knud Howard Poulsen and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2000 with Geology categories.
This bulletin 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 of bedrock gold deposits are distinguished and their main geological attributes are summarized. These do not correspond to an equal number of genetic types; many of these deposit types represent different components of larger hydrothermal systems and are genetically related. Most of the deposit types identified are represented by at least one large example (containing over 100 tonnes of gold). Descriptions are provided of Canadian gold deposits, including Archean & Proterozoic deposits in the Canadian Shield, Late Proterozoic to Palaeozoic deposits in the Appalachian Orogen, and Mesozoic to Cenozoic deposits in the Cordilleran Orogen. The final section discusses the application of gold deposit models.
