Abstract

Abstract: On the basis of tectonic-background analysis and drilling and log responses, electrofacies analyses were made on the pale-okarstic strata in Xuhei-Chengbei terrace region. Criteria for recognizing paleokarst zones were established, and evolutionary pattern of karstification was determined based on the regional tectonic history. The main factors leading to the development of paleokarst in the region were found to be multi-phase tectonic
cycle, complicated fault-block tilting and long-term dissolu-tion by chemically active fluids.

Key words: paleokarst, electrofacies, criteria, evolution-ary pattern, relative permeability
