Characterization of fracture surfaces in dolomite rock, Culebra Dolomite Member, Rustler Formation
- New Mexico Univ., Albuquerque, NM (USA)
The Culebra Dolomite Member, Rustler Formation, southeastern New Mexico, is characterized by a high fracture porosity. Bedding plane fractures are predominant, but vertical and high-angle fractures are also common. The information presented in this report for horizontal fractures shows that: horizontal water-bearing fractures in dolomite and calcite rock tend to occur in zones where clay and quartz are concentrated, particularly along clay seams, and secondary minerals, primarily gypsum and some calcite, are precipitated from solution onto the fracture surfaces. No surfaces of vertical or high-angle fractures that were clearly identifiable as water-bearing were discovered in the cores examined. 4 refs., 30 figs., 7 tabs.
