Geological hammers come in a few different sizes, and therefore weights. My experience has been that hammers around the 22-24 oz weights (680 gms) are perfect. They are heavy enough to provide a good impact when swung but don’t weigh you down when hiking around the field. Larger heavier hammers also have their place – but more …TITLE: GEOLOGIC LOGGING CATEGORY: GEO 4.8 REVISED: March 1998 1. Introduction Geologic logging involves keeping detailed records during the drilling of boreholes, the installation of monitoring wells, and the excavation of test pits, and entering the geologic de­ scriptions of the soil and rock samples recovered on a standardized form.
