| Sumario: | [eng] The French speleologist Robert de Joly carried out a campaign on the island of Mallorca at the beginning of 1929, in which he applied the numerous technical innovations that gave him some international fame in the field of cave exploration. Several comrades were involved in this speleological campaign, including the geologist Georges Denizot and the archaeologist Henri Bauquier. During the almost two weeks that their activities lasted, they explored some interesting caves including Cova Figuera (Manacor), Cova Nova de Son Lluís (Porreres), Avenc d’en Corbera (Esporles), as well as Cova de les Rodes (Pollença) that hosts a small underground stream unknown until then. Some important chasms were also descended, such as Avenc d’en Trau (Andratx), Avenc de sa Marineta (Deià), or Avenc de Son Mas (Valldemossa) which became the deepest pot-hole in Mallorca at that time, with its depth reaching -83 m. This campaign did not provide any topographic survey of the visited cavities, limiting itself only to their written description. From the geological and morphogenetic perspectives, the contributions were quite modest and some of them not very accurate; however, interesting observations related to well-known caves such as Coves del Drac (Manacor) were supplied, including an explicit refutation of its marine genesis postulated by Édouard-Alfred Martel at the end of the 19th century. |
