Magma prospecting in usu volcano
WebMagma is the molten rock that lies several kilometres below the Earth's surface. It contains many minerals that we want, but in very dilute form. It's better to let nature concentrate them for us before we try to mine them. There are two main processes: Preferential crystallisation concentrates minerals when the magma moves towards the Earth's ... WebMay 7, 2010 · Abstract. We estimated the depth of the magma chamber system beneath Usu volcano, one of the most active volcanoes in Japan, by melting experiments on the eruptive product of the ad 1663 plinian eruption (Us-b pumice). This pumice is a low-K rhyolite with a K 2 O content of only 1 wt %. The experiments were conducted using …
