La ???Piedra de Sierra Elvira??? constituye una de las piedras ornamentales m??s significativas del Patrimonio Arquitect??nico de Andaluc??a Oriental. Es una roca caliza\uddel Lias que aflora en el Subb??tico Medio del sector central de las Cordilleras B??ticas. El litotipo m??s explotado es\uduna caliza con crinoides, en bastante menor importancia se ha extra??do tambi??n otra caliza micr??tica de la misma edad. Los bancos son muy potentes, en algunos casos de\udm??s de 5 m, con un paralelismo constante y un buzamiento que favorece su explotaci??n en los frentes de cantera.\udSus caracter??sticas petrogr??ficas y f??sico-mec??nicas le confieren una calidad t??cnica y durabilidad muy notables para su utilizaci??n como material de construcci??n estructural y ornamental. Los principales par??metros que determinan estas cualidades son su m??nima porosidad eficaz y asociado a ello sus excelentes propiedades h??dricas, as??\udcomo sus elevadas resistencias mec??nicas y el bajo coeficiente de anisotrop??a textural, tanto el??stico como mec??nico. Este conjunto de caracter??sticas ha permitido su utilizaci??n en muy diversas funciones constructivas.???Sierra Elvira stone??? is one of the ornamental building stones most widely used in the historical monuments of eastern Andalusia. A Liassic age limestone, it appears in the central section of the Baetic Mountains and more specifically in the Middle Subbaetic domain. While the most common variety is a crinoid limestone, a micritic limestone of the same age has also been quarried, albeit in much smaller quantities. These stones form very thick beds, up to nearly 5 m deep, that run in consistently parallel lines and have a dip angle that facilitates quarrying.\udWith petrographic, physical and mechanical properties that ensure stone strength and durability, it is a high quality building material suitable for both structural and ornamental purposes. These properties can be attributed to the minimal open porosity and concomitant excellent water resistance that characterize the stone, as well as to its high mechanical strength and low textural anisotropy, both elastic and mechanical. With such attributes, the stone can be successfully used for any number of purposes, including decorative stonework (portals, fountains, plinths), structural members (column shafts and bases) or urban curbing and paving. Intervention on Sierra de Elvira limestone structures should be limited to cleaning or repair, for consolidating or protective materials are scantly effective
