Figure 5. Legend for symbols used to represent lithologic accessories, trace drilling disturbance, and contact types in barrel sheets (see Section 4, this volume). Slight, moderate, and extreme core disturbances are represented in the barrel sheets as thin, medium, or thick solid lines, respectively. The relative abundance of lithologic accessories present within cores is denoted in the barrel sheets by dotted, dashed, thin solid, medium solid, and thick solid lines for rare, moderate, common, abundant, and pervasive abundances, respectively.
