No single rating entry fits this description exactly, but that of ‘rough or irregular, planar’ seems most appropriate for such a large-scale feature as a bedding plane. The rating value is then 1.5. The jointing is slightly weathered and slightly rough. WebFor example, where one type of rock contacts another, there is a geological boundary, a type of structure. Geological boundaries include: faults; bedding planes; the edges of igneous intrusions (intrusive contacts) ancient erosion surfaces (unconformities) You should have heard about all these types of boundary in your introductory courses. cheap motel in boston massachusetts
