I'm copyediting as I go; please revert if I mess anything up.
This region of volcanism spans the borders of Peru, Bolivia, Chile and Argentina and contains a number of individual volcanic centres, including the world's two highest volcanoes Ojos del Salado and Llullaillaco.Not really necessary in the lead; suggesting cutting this and merging the first two lead paragraphs.
6,145 metres (20,161 ft), 6,142 metres (20,151 ft) or 6,163 metres (20,220 ft) high San Pedro: ugly; can we find a more readable way of giving the alternative heights? Maybe pick an authoritative one or the most recent, and give the others in a note?
prismatically joined blocks: what does this mean?
instead features groves and radial ridges: should this be "grooves"?
which dropped down an elevation difference of about 2,845 metres (9,334 ft): not sure what is meant by "dropped down" here.
a lava dome at an elevation of 5,000 metres (16,000 ft) dots the southwestern flank of San Pedro: "dots" requires a plural subject.
Either cone, San Pedro volcanic rocks belong to...: suggest "In each cone, San Pedro volcanic rocks belong to..."
one eruption reported from 1877 may instead have occurred in 1891: that seems odd enough to be worth an inline explanation, if it's easy to give one.

Two points left: it's "prismatically" that is baffling me. To me it means "in the manner of a prism" and I can't see what it's telling me. Is it a standard technical term? Second, the "dots" point is unaddressed. Once can say "plants dot the landscape", or use a mass noun like gravel to make a plural that functions like a singular: "gravel dots the ground", but I don't think you can say "a tree dots the landscape". How about " a lava dome at an elevation of 5,000 metres (16,000 ft) on the southwestern flank of San Pedro seems to be a parasitic vent"?

The southwestern dome is situated at about 5000m on the southwestern flank of San Pedro, and overlies pumice flow H; I'll see about another wording. Jo-Jo Eumerus ( talk, contributions) 11:29, 26 February 2018 (UTC)

San Pedro is a composite volcano in northern Chile and one of the tallest active volcanoes in the world. It is part of the Andean Volcanic Belt and, like other Andean volcanoes, was formed by the subduction of the Nazca Plate beneath the South America Plate. San Pedro is formed of two separate edifices, the Old Cone and the Young Cone, and is adjoined to a neighbouring volcano, San Pablo. The Old Cone was active over one hundred thousand years ago and was eventually truncated by a giant landslide that removed its northwestern side. Within the landslide scar lava flows and pyroclastic flows constructed the Young Cone as well as the lateral centre La Poruña. Some eruptions have been reported during historical time, and presently the volcano is fumarolically active. This photograph shows San Pedro in the foreground, with San Pablo visible behind it to the right. Photograph credit: Diego Delso
