美國(guó)夏威夷島上的基拉韋厄火山已持續(xù)噴發(fā)了43天,一種被叫作橄欖石的小綠寶石像下雨般落在街道和海灘上。
The minerals are found in volcanic rocks and land around Hawaii. They have always been there but have been dislodged by the recent eruptions and are coming shooting down on resident as a result.

Olivine is a green mineral which has been used for centuries to make jewelry, and in some cases, can be worth as much as $450 per carat.
橄欖石是一種綠色礦石,幾個(gè)世紀(jì)以來(lái)一直用于生產(chǎn)珠寶,有時(shí)每克拉價(jià)值可高達(dá)450美元。
Cheryl Gansecki, a geologist at the University of Hawaii-Hilo that studies the composition of Kilauea's lava, told Mashable that there were two reasons the gems were being discovered more frequently because of the eruptions.
專門研究基拉韋厄熔巖的夏威夷大學(xué)希洛分校的地質(zhì)學(xué)家謝麗爾·甘瑟斯基向Mashable網(wǎng)站透露,該寶石在火山爆發(fā)期間較頻繁出現(xiàn)是由兩個(gè)原因造成的。
'The lava that is erupting now is very crystal-rich and it is quite possible that residents might be finding olivine. It can be carried in the pumice pieces that have been rained all over the area or left behind when weaker lava rocks are crushed,' she said.
