Rodingitización y formación de pectolita en diques graníticos de las Peridotitas de Ronda (Cordilleras Béticas, España)

Abstract

This work reports the local occurrence of rodingites formed from granitic dykes intrusive in the Ronda Peridotites. Representative mineral assemblages include chlorite, hydrogrossular, and prehnite but also pectolite, and xonotlite uncommon mineral in rodingites. In addition, some granitic dykes are characterized by the albitization of plagioclases. The development oflizardite in the adjacent serpentinites suggests that rodingitization was a low-temperature metasomatic process, which affects the granitic dykes in contact with peridotites during serpentinization
