Part of Chile's segment of the Andean volcanic chain, it is part of the Central Volcanic Zone of the Andes: "part of...part of".
The term taapaca may also be the origin of the term tarapaca: As "tarapaca" is a red link, could we get an inline explanation of it, since without that this isn't much use -- I'm assuming it's "taapaca" that could be a name for Viracocha. And why redlink to a dab?
with a noted increase about 27 million years ago: "noted" doesn't seem like the best choice here. Presumably we mean the increase was substantial, rather than just notable; can we find an adjective such as "substantial" to indicate that?

Continuing:
The largest eruption in the Central Volcanic Zone occurred at Huaynaputina in 1600: should this be "largest recorded eruption"?
Taapaca is located on the Altiplano, more specifically on its western margin where the Western Cordillera has developed since the Oligocene.Suggest "Taapaca is located on the western margin of the Altiplano, where the Western Cordillera has developed since the Oligocene."
sizes and shapes ranging from almost circular to ellipse shaped constructs: two points here. We give different shapes, but we don't give examples of different sizes; and could this be shortened to "from almost circular to elliptical"? "Elliptical" means "ellipse shaped", and "constructs" doesn't seem necessary.
generazed: typo for "generated"?
and reflects a calc-alkaline nature of magmatism: not sure what this is saying. Do you mean that the magma here is calc-alkaline in nature? Perhaps "and reflects the calc-alkaline nature of the local [or "regional", or "of Taapaca's"] magma"?
The formation of the magma has been inferred to occur through the initial mixing of basaltic andesite which is the typical calc-alkaline volcanic arc basalt with basalt derived from melting of sub-crustal basalt cumulates and the subsequent interaction of the resulting mixture with rhyodacite melts derived from Proterozoic crustal material; the initial melt contributes most of the material in mafic inclusions and the rhyodacite contributes most of the dacite material.A long and complicated sentence. Can it be broken up?
Pausing there for now. Mike Christie ( talk - contribs - library) 19:02, 12 May 2018 (UTC)
Continuing:
the noticeable Azorella compacta: what is "noticeable" telling me? Is it unusual, or does this mean it is seen everywhere?
The recurrence interval of eruptions at Taapaca is about 450 years: this seems to be in conflict with the information in the eruptive history section.
That's it for a first pass. This looks pretty clean to me; I will do another prose read through once these points are all addressed, but it seems close to ready. Mike Christie ( talk - contribs - library) 12:00, 13 May 2018 (UTC)
In particular, although lahars are typically associated with the effects of volcanic activity, lahars can occur even without any current volcanic activity, as long as the conditions are right to cause the collapse and movement of mud originating from existing volcanic ash deposits.
One more point:

Second pass:
starting during the Pliocene and Pleistocene: it can't have started during both.
The emplacement of lava domes was often accompanied by their collapse: this makes the events sound simultaneous; better to use a verb that indicates sequences -- perhaps "followed".
The subduction process generates fluids that are ultimately responsible for the evolution of subduction-associated magmas when they interact with the mantle wedge above the subducting plate.Any way to eliminate one of the three "subduct-" words in this sentence? And the very next sentence has three more (though I added one of them myself in a copyedit).
It consists primarily of overlapping lava domes, of which there are many at Taapaca, with shapes ranging from almost elliptical to circular: how about "It consists primarily of many overlapping lava domes, with shapes ranging from almost elliptical to circular."
block-and-ash flows up to 13 kilometres (8.1 mi) long and with thicknesses 20 metres (66 ft)-less than 2 metres (6 ft 7 in) thick farther away from the volcano have covered a surface of 110 square kilometres (42 sq mi): something wrong here; should it be something like "with thicknesses of 20 metres, down to less than 2 metres thick farther away..."?
At this time, Taapaca likely was a large stratovolcano[47] consisting of steep lava domes: I thought stratovolcanoes and lava domes were separate categories of volcano?
I really would like to see some kind of map or diagram to show the relationship of the various units and the geographical entities. I'll dig around on the web for sources of satellite imagery and see what I can find. Mike Christie ( talk - contribs - library) 01:06, 16 May 2018 (UTC)
