STEREOLOGICAL INTERPRETATION OF JOINT TRACE DATA: INFLUENCE OF JOINT SHAPE AND IMPLICATIONS FOR GEOLOGICAL SURVEYS

The paper presents a new statistical model for the geometrical and spatial distributions of joints, incorporating a joint shape based on the parallelogram. The model is linked with geological surveys by analytical predictions of trace patterns, covering area and line sampling, distributions of trace lengths and spacings, and allowance for truncation. Care is taken to express the equations in suitable forms for numerical evaluation. The predicted trace patterns are examined over the full range of exposure orientations and are shown to be generally consistent with reported observations. Implications for geological surveys are discussed in some detail, together with ways of obtaining the parameters of the model from field data. The significance of the present theory is that it suggests a new approach to data collection and interpretation and establishes a stereological framework that can readily allow for future model developments.(a) (TRRL)
