Abstract

A number of empirical laws which state that a simple relationship exists between the size and ranking of objects have been used in assessing undiscovered petroleum and minerals resources. The most well known of these, the log-log and log-linear laws, are described and compared with log-normally distributed statistics which I have assumed give a good description of sizes of petroleum and mineral deposits. The log-log law, which states that the log of size of a mineral deposit plots as a straight line against the log of the rank of the deposit sizes, was found to give a fair fit for the bigger deposit sizes, but the smaller sizes would be over-estimated. The log-linear law which states that the log of size of a deposit plots as a straight line against the rank of the deposit sizes was found to give a poor fit for both the big and small sizes. The log-log law may be useful for assessing undiscovered resources where geological analogues exist and the largest deposit can be assessed by other means.
