El Gres: un hito geográfico, económico y simbólico. Los sistemas de cazoletas y canalillos en la comarca de els Ports

The open-air engravings of the northern part of Castellón province (Spain) are usually made on sandstone outcrops. The geology of Els Ports region determines a rigid organization of land exploitation, caused by a shortage of soft lithology to grow. As a result, coastal Cretaceous formations (loams and clays) concentrate the archeological sites and the traditional-farmer settlement. Derived to this, sandstone outcrops of these coastal formations include large part of the fifty known engraving sites. We have documented several aspects about the style, the slope of the engraved blank and the position of the site, identifying some relations between system’s morphology, place and function. Some of these systems types can be analyzed from an archaeological and geological framework, and they offer important conclusions about some of the connected cup-marks systems
