Sumario:Until very recently, most of the caves in Mallorca were considered to be of epigenic origin, where the endokarst phenomena was mainly originated by the circulation of meteoric waters carrying biogenic CO2, and by different speleogenetic mechanisms associated to the littoral mixing zone along with extensive breakdown processes. The breakthroughs achieved along the last years have contributed not only to identify new morphologies, but also to distinguish a new speleogenetic process hitherto unknown in Mallorca: the hypogenic speleogenesis, related to a water recharge of deep origin. To address challenging questions regarding with it, a detailed investigation of suspicious caves harbouring hypogenic evidences was carried out, yielding unexpected data. In this paper, special attention is given to the morphological signs found predominantly in caves located within the south-western sector of Migjorn karst region and surrounding area. The following morphologies have been documented: a morphologic suite of rising flow integrated by feeders, rising wall channels and outlets; dead ends; partitions; the associations of cave rims–vents and bubble trails–folia; as well as likely condensation-corrosion features in the form of bellholes and small subspherical chambers.
