Prominence of ichnologically influenced macroporosity in the karst Biscayne aquifer: Stratiform “super-K” zones

Kevin J. Cunningham, Michael C. Sukop, Haibo Huang, Pedro F. Alvarez, H. Allen Curran, Robert A. Renken, Joann F. Dixon
Journal: GSA Bulletin
Published: 01 January 2009
GSA Bulletin (2009) 121 (1-2): 164–180.
