Abstract

A quantitative analysis of laminaset geometries has been used to compare subsurface core with potential outcrop analogues. The Rannoch Formation core is characterized by numerous low angle truncations. We have measured these features in two wells (means of 7.2° and 12.1°). Mean apparent set thicknesses were 0.24 and 0.19m. In the outcrop sections studied, truncation angles ranged from 9.6° to 13.4° and mean set thicknesses from 0.24 to 0.34m. Mean bounding surface dips and 5.8° and 8.6°, and mean laminaset lengths of 2.3 and 4.1m were also measured, directly in the field and by using photomosaics. -from Authors
