Primary dispersion (lithogeochemistry) patterns were determined for tin-bearing intrusive granitic phases of Late Cretaceous age, Seward Peninsula, Arkansas, using exploration bedrock (lithogeochemistry) at the Kougarok tin prospect. Tin was determined to be its own best pathfinder element from statistical analysis of the three dimensional data base that was assembled from exploration drilling data. Arsenic is a pathfinder element; it forms a discrete halo peripheral to the tin mineralization, and can be recognized in hand specimens by arsenopyrite and/or scorodite staining. Tin, tantalum, and niobium are concentrated in the igneous rocks containing the largest amount of fluorine-bearing minerals. Computer processing and high resolution graphics display of geochemical data were used to quickly, accurately, and efficiently obtain important data. Among these are: 1) the various concentrations of elements of interest, and the basic geometry of the different lithologic units. These techniques permit timely responses to what if questions, and the convenience of testing geologic concepts prior to laborious hand construction of geologic sections in mineral exploration.
