Gold deposits can take many forms. The distribution of gold within a deposit may be relatively systematic, in which case it is possible to accurately estimate the resource with minimal data. In other cases, the distribution of gold in the deposit may be very irregular (known as "nuggety") and difficult to estimate. This difficulty delays mine permitting and creates challenges for resource extraction. I hypothesize that a fundamental difference in the way gold is transported and deposited by fluids may help explain the differences between deposit styles and provide tools for understanding the structural controls on gold grade.

金矿可以有多种形式。金在矿床内的分布可能是相对系统的，在这种情况下，可以用最少的数据准确地估计资源。在其他情况下，金在矿床中的分布可能非常不规律(称为“块状”)，很难估计。这一困难延误了采矿许可，并给资源开采带来了挑战。我推测，金的运移和流体沉积方式的根本不同，可能有助于解释不同矿床类型的差异，并为理解构造对金品位的控制提供工具。
