This report gives the results of a research project undertaken to locate sources of base course materials in the Gulf Coastal regions of Texas. The sites that were found are used as case studies to illustrate the principles of exploration for each of the different types of aggregate that were found, including sandstones, river gravels, and high gravels. The exploration always starts on a broad scale using maps, aerial photographs, and color-infrared images to delineate areas with a high potential for producing aggregates. The forms and shades of color that these deposits take on are different in wet, east Texas than they are in dry, southwest Texas. A more refined investigation is undertaken in the more promising areas using either seismic or resistivity techniques to delineate the depth and extent of the deposits. These techniques are explained so that the way they operate can be easily understood and put into practice. The final step in the exploration process is an actual drilling, coring, sampling, and testing program which will prove out the deposit. This report does not contain sufficient detail to provide a strong working knowledge of some of the remote sensing methods. However, the references necessary to gain this working knowledge are included in this text.
