Sa Corona 'e sa Craba area, whose name in Sardinian means "The crown of the goat", was explored for Pb, Zn and Ba ores in the early 1930s, and economic exploitation went on for a little more than 30 years after 1950.
A natural cave, located to the SE of Barbusi village and named Sa Corona 'e sa Craba cave, is entirely developed within a quartzite vein at the contact with Cambrian dolostones. Its natural entrance, enlarged during mining operations, opens at 260 m a.s.l. It is composed of an over 200 m long and 20 m wide gallery developed in a NW-SE direction. The cave was discovered in 1971 by cavers of the Gruppo Ricerche Speleologiche E.A. Martel of Carbonia and, because of its mineralogical interest, became immediately the object of intense collection activities. The cave is composed of a series of rooms entirely developed inside the quartzite rocks. The host rock appears dark, greyish to brownish. Carbonate speleothems, typical of caves carved in limestones and dolostones, are missing. After the first room, the cave continues with a wide and high gallery that hosts a large guano deposit generated by an important bat colony inhabiting the cave during spring-early summer.
The cave is well-known among minerals collectors for baryte (in gorgeous crystals turning bluish when exposed to light), calcite, quartz, dolomite, and aragonite. The study of fluid inclusions found in baryte suggests their deposition at a temperature lower than 50°C, only when the rising reducing fluid became more oxidative (Sauro et al., 2014). Various secondary sulfates, phosphates, silicates, and oxihydroxides have been identified in recent times (Baldoni et al., 2013; Sauro et al., 2014; D'Angeli et al., 2018; Audra et al., 2019).
