The most reliable radiometrically obtained dates for this ignimbrite indicate an age of 73,000 years; previous estimates of their age were 560,000 B1 110,000 and 440,000 B1 10,000 years before present. The 73,000 age is considered to be more reliable but in 2022 an age of 54,600 B1 600 years was proposed for this eruption. The eruption reached level 6 on the Volcanic Explosivity Index and is also known as the first cycle ignimbrite. The eruption has been described as the largest caldera collapse at Cerro Blanco but the source vent for this eruption has not been found, and there is no agreement whether the Robledo Caldera is the source. The volcano-tectonic depression northeast of Cerro Blanco or the Pie de San Buenaventura and El NiC1o scarps have been proposed as a source. As with the Cortaderas Synthem, this ignimbrite was produced by a boiling-over vent and the pyroclastic flows lacked the intensity to override local topography. It is possible that the eruption proceeded in two phases, with a magmatic reinvigoration of the system between the two. After the ignimbrite cooled and solidified, cracks formed in the rocks and were later eroded by wind. The Campo de la Piedra PC3mez Ignimbrite crops out mainly on the southeastern and northwestern sides of the Carachipampa valley, as between these two outcrops it was buried by the later Cerro Blanco ignimbrite; other outcrops lie in the Incahuasi and Purulla valleys. The Robledo and Pie de San Buenaventura calderas were formed during the early activity.
