Published multi-element stream-sediment exploration geochemical data from new brunswick are used to illustrate some pitfalls of correlation and regression. Large matrics of correlation coefficients. are easly mass-produced.These coefficient are susceptible to suprious values, clustering of samples and the effect of other variables on the relation un…
Fundamental questions of metallogenetic investigations are first donsidered. The difference betwen factors and indicators in metallogenetic analysis is discuss.Metallogenetic factors are geological phenomena which condition the formation of deposits.They are its cause.
An om a l .i es of s u l f u r d i ox i de and other gases have been defined, by direct measurement, around various sulfide bodies. These readings were made (1) in soil gas and (2) in the atmos• phere, from bo…
Manganese oxide coatings on gravels from 255 sites on tributary streams in the genesee river watershed were analyzed for Mn, Fe, Zn, Cd, Co, Ni, Pb and Cu. The result were compared with data on bedrock geology, surficial geology and land use, using factor analysis and stepwise multiple regression. All metals except Pb show strong positive correlatio…
methods can thus often be based on the measurement of trace quantities of the metal itself in waters, soils, sedi• ments or rocks. In Canada, for example, centre-lake sedi• ments and lake waters have been widely used during the National Geochemical Reconnaissance survey (Cameron A new t…
India has finalized plans to begin a massive magnetite ore mining project which will use some of the most sophisticated mining and refining operations to date. The Kudremukh Iron Ore Project, a cooperative trade agreement between Iran and India, will allow India to tap her vast mineral reserves and export the end product to Iran. HE KUD…
This morning (afternoon), we will discuss the various types of equipment used for the recovery of valuable- minerals from their ores. These minerals may be physically or chemically liberated from their host material and, in general, the same type of equipment is used in both process~s. Before discussing the particular machinery used for proces…
