That troglobite is 1. an animal living permanently underground in the dark zone of caves and only accidentally leaving it [10]. 2. a creature that is fully adapted to life in total darkness and can only complete its life cycle underground [13]. 3. a creature that lives permanently underground beyond the daylight zone of a cave. many troglobitic species are adapted in some way to living in a totally dark environment. synonyms: (french.) troglobie; (german.) troglobiont; (greek.) troglothitis; (italian.) troglobio; (russian.) troglobiont; (spanish.) troglobio; (turkish.) troglobit, kor balik.?

RESERVOIR CHARACTERISTICS OF THE COMPLEX KARST OF THE LLUCMAJOR PLATFORM, MALLORCA ISLAND (SPAIN): TOOL FOR HYDROCARBON RESERVOIR APPRAISAL

Abstract:
The development of porosity in carbonate platforms takes many forms. Dissolution porosity as a result of karst processes is unique as it produces organized porosity and permeability over a variety of scales, and can do so in very short periods of time, geologically speaking. Karst developed in the Miocene formations of the Mallorca Island exhibits a complexity that seems to be very similar to the Kashagan or Aktote (Kazakhstan) or Kharyaga (CIS) karst reservoirs architecture characterized by different phases of island karst (mixing water) type with caves of different sizes and sponge karst, reworked and partly filled by paleosoils related to plateau karst developed during major sea level drops and finally hydro- (geo)-thermal processes. The Miocene rocks of the Llucmajor platform in the southwest of Mallorca island exhibit the three main types of karst developments that occurred through time, linked or not to glacio-eustatic changes: -1 Island karst (the flank-margin model); -2 Meteoric karst; -3 Hydrothermal karst/ These developments allow defining the so-called Complex Karst. Each of the terms is identified by specific overprints found in drilled wells (logs and cores) or on outcrops. The outcrops and subcrops of Mallorca Island represent an excellent analogue for understanding the complexity of the past carbonate platforms which are hydrocarbon targets for the industry
