Wulkan Shield

Shield wulcan are among thee largett wulcan one Earth by volume, yet they are specifized by a deceptively simple shape: a broad, gently sloping dome that resemble a contayor 's shield. Their low profile is a direct consusence of thee fluid nature of the lava that builds them.

Charakterystyka wulkanów Of Shield

  • Xi1; Xi1; FLT: 0 XI3; XI3; Basaltic Lava: XI1; XI1; FLT: 1 XI3; XI3; THE magma erupted at shield vulcan es is almost exclusively basaltic, with very low silica content (typically 45- 52%). Thi low silica content means the lava has low visity and can flow great distances before solidardifying.
  • Xi1; Xi1; FLT: 0 XI3; XI3; XI3; XILE SLOPES: XI1; XI1; FLT: 1 XI3; XI3; XI1; THE typical slope of a shield wulcan is only 2-10 disones. ThE wige, flattened shape results frem repeated, far- traveling lava flows that spread in all directions frem thel central vent or rift zones.
  • Refl1; FLT: 0 is 3; Effusive Eruptions: Xi1; Xi1; FLT: 1 is 3; Xi3; Eruptions are usually non-explosive (effusive). Lava fountains may occur, but the overall style is dominated byy quiet outpourings of lava rather than violent blasts. This allows the convolco to tano grow steadly over hundreds of exterands of years.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Calderas: Xi1; Xi1; FLT: 1 XI3; Xi3; Many shield vulcan sumit is marked by a caldera - a large, basin-shaped deppion formed by the fallsie of te te gerad after magma is accorn from a shallow w chamber. Examples include the sumit calderas of Mauna Loa and Kilauea.
