2 Geological Setting and Sampling. The nine volcanic islands of this Azores Archipelago straddle the triple junction associated with North‐American, Eurasian, and Nubian lithospheric dishes into the mid‐North Atlantic Ocean

The nine volcanic islands of this Azores Archipelago (36.9В°N–39.8В°N, 24.9В°W–31.3В°W) straddle the triple junction associated with the North‐American, Eurasian, and Nubian lithospheric dishes into the mid‐North Atlantic Ocean (inset of Figure 1). Pico Island (447 kilometer 2 ) comes with an elongated form with a maximum length of 46 and 16 kilometer, correspondingly. It’s the youngest area regarding the Azores Archipelago (270 В± 150 ka; Demande et al., 1982 ) and it is consists of three volcanic systems: Topo volcano, Planalto da Achada fissure area and Pico volcano (Figure 1). Topo is definitely an extinct volcano situated in the southern the main area this is certainly profoundly eroded and included in more youthful lavas. Planalto da Achada fissure zone corresponds up to A wnw‐ese‐oriented ridge of scoria cones, в€ј30‐km long, that forms the eastern area of the island. Pico volcano could be the youngest volcano associated with archipelago (53 В± 5 ka; Costa et al., 2014 ) and comprises the western an element of the area. This volcano that is central described as mild reduced slopes with numerous scoria cones, rising as much as 2,351 m being a conical form edifice with high slopes toward the very best (Nunes, 1999 , 2020 ; Zanon et al., 2020 ). The geological record of Pico Island reveals a higher eruptive usually through the datingmentor.org/escort/columbia/ Holocene (Nunes, 1999 ). Planalto da Achada fissure area erupted at the very least 13 times within the last 2,000 years and Pico volcano erupted 22 times within the last 1,500 years (Nunes, 1999 ). Read more
