The first two types of setting are well represented in the North American Precambrian Shield; the third one is found along the North Amer

They are truly “stratiform” deposits, i.e., occurring as continuous and extensive blankets concordant with the encasing sediments, as opp

Evaluation of the Probability of Detection of Mineral Deposits, approach to the problem of detection, namely, the direct and indirect methods, which are commonly used simultaneously or sequentially to best advantage. Table 2.1 summarizes the main aspects of the two paths with respect to the types of target sought and detection environment, as well as the methodology and procedures involved.

The spectacular successes of the 1960s and the 1970s resulting from the massive injection of new technology were often accompanied by much waste of talent and resources and unnecessary duplication which cannot be repeated in the present circumstances of economic difficulties and financial stringency.
