La plate-forme du Yucatàn (Mexique)
HeraudpiÑa, M. A.
Abstract:
The Platform of the Yucatan peninsula, south of Mexico, is constituted by a tertiary carbonated series (Eocene to Pliocene). The karst landforms are a "Kuppenkarst" whose positive reliefs are more conspicuous in the centre because of greater altitude (0 to 400 m). Most caves are developed under the base level. The cenote corres-ponds to drowned pits which can be 100 m deep or more. The flooded caves, like Nohoch Nah Chich (40km long), are the longest in the world. The history of karstification began during the Tertiary, between the end of Eocene to Pliocene in relation with uplift. The crypto-dissolution occurs under an alte-ritic cover which comes from a former silicated detritic cover (south peninsula crystalline massif). Speleogenesis depends on the halocline i.e. mixing corrosion zone (salt water/fresh water) and the fluctuations of the sea level.
