    The Greenstone Flow is one of the world's largest known lava flows, estimated at a volume ~1650 to ~6000 cubic kilometers of mafic lava. [2] [3] In places, the lava pooled to depth of 487 meters. [4] The flow was generated by a flood basalt eruption during the Midcontinental Rift, which occurred 1.1 billion years ago. [5]

    The volcanic field consists of two lava flows, the Broken Back flow and the Carrizozo lava flow (Carrizozo Malpais), the second youngest in New Mexico. [5] Both lava flows originated from groups of cinder cones. The Broken Back flow is approximately 16 kilometres (10 mi) long and the Carrizozo, one of the largest in the world, is 68 kilometres ...
