ABSTRACT
Geology, Hydrogeology and protection of Cervantes Spa in Santa Cruz
de Mudela (Ciudad Real)
Cervantes spa is situated, geologically, in the south east of Centro-Iberia Massif,
and near it there are several mountains, the Acebuche and the Águila, of preferent
direction North West-South East and West-East, in wich one can find a large
amount of slates, quarzites and sandstones, very some volcanites and limestones,
all of them from paleozoic age, separated by depressions filled with sediments
made by sands and clays.
The acuifer by the main well of the spa, named Bilbao, its associated to a quartz
formation, sometimes affected by fissures and fractures of preferred direction SSW
– NNE, inside the ordovicis slates, exploted in the antimony old mines.
Its waters proceding from the water filtration from the rain in the mentioned
paleozoic and terciary outcrops, they‘re acid, very mineralized and with high con-
teins of carbonic anhidrid originally endogenous, increasing through the brekage
and fissures related to the volcanic activity of the area.
The carbonic waters of the spa wells, denominated Bilbao and Villa Rosa, are
protected in quantity and quality by a mining perimeter protection of 2.308 hec-
tares.

Estratigrafía general de la zona
El balneario Cervantes, situado en el paraje del Salobral del tér-
mino municipal de Santa Cruz de Mudela (Ciudad Real), se encua-
dra, desde el punto de vista geológico, en el extremo suroriental de
la zona Centro-Ibérica del Macizo Ibérico [1], que se extiende desde
el Macizo Galaico-Portugués al noroeste de la península Ibérica hasta
la depresión del Guadalquivir al sudeste.
En esa zona y en sus proximidades existen varias cadenas mon-
tañosas, Sierras del Acebuche y del Águila de dirección preferente
NO-SE y O-E, en las que se encuentran abundantes pizarras, cuar-
citas y areniscas, y algunas vulcanitas y calizas, todas ellas de edad
paleozoica, muy tectonizadas y separadas por depresiones rellenas
de sedimentos constituidos por arenas y arcillas terciarias y cuater-
narias (Fig. 1).
