Gran Canaria, Pico Basilé and Tenerife as pyroclastic shields edit
Interesting if true, but I have my doubts. The sources involved confirm they are shield volcanoes who have also had pyroclastic phases during their volcanic life cycles, but does that make them pyroclastic shields? From the description of pyroclastic shields in the article, I get the impression that pyroclastics are part of their eruption style as shield-building volcanoes. But the volcanoes in question seem to have shifted from chiefly one style of eruption (basalt shields) to chiefly another style (pyroclastic cones) over a long time. - Gilgamesh (talk) 11:41, 29 May 2019 (UTC)
- I don't think I've seen any source refer to Gran Canaria or Tenerife as "pyroclastic shields". Jo-Jo Eumerus (talk) 13:17, 16 July 2020 (UTC)
- Yes, I retain similar doubts, about those and Pico Basilé. But I suppose, as a retentionist at heart, I would prefer we are thorough with fact-checking before removing them from the list. Thing is, my level of knowledge on pyroclastic shields is limited to Wikipedia and whatever a superficial Google search will provide. This topic needs the attention of an expert who'll know what reliable references to cite and what citations simply won't exist. - Gilgamesh (talk) 12:50, 19 July 2020 (UTC)
- These are not examples of pyroclastic shields and a claim that they are pyroclastic shields is not supported by the cited source references. The editor who added these examples seems to have misunderstood their own sources. Pyroclastic deposits occur at many shield volcanoes but only a few shield volcanoes are pyroclastic shield volcanoes. Also, the Las Cañadas volcano of Tenerife was/is actually a stratovolcano not a shield volcano. Therefore, I shall delete these three entries from this article's list of examples.
