On the Drake Passage, between the tip of South America and the South Shetland Islands of Antarctica, there is a small island. The island is the caldera of an active volcano, eerily called Deception Island on account of its "outward deceptive appearance as a normal island" 🌋 1/6

Cristobalite and diktytaxitic textures are common in lavas. Do they influence rock properties? We try to answer this question by measuring rocks from submarine volcano Havre 🌋
