There are two kinds of hydrothermal vent: black smokers and white smokers.

黑烟囱和白烟囱。

Black smokers release acidic, carbon-dioxide-rich water, heated to hundreds of degrees Celsius and packed with sulphur, iron, copper, and other metals essential to life.

黑烟囱释放出富含二氧化碳的酸性水，这些水被加热至数百摄氏度，并含有硫、铁、铜和其他对生命至关重要的金属。

But scientists now believe that black smokers were too hot for LUCA— so now the top candidates for the cradle of life are white smokers.

但科学家现在认为，黑烟口的温度对LUCA来说太高了——所以现在白烟口成为了生命摇篮的热门候选人。

Sometimes the chimneys are called white or black smokers because the erupting fluids full of minerals look like smoke rising out of the towers, but the whole accumulations are known more formally as massive sulfide deposits.

有时烟囱被称为海底白烟囱或黑烟囱，因为充满矿物质的喷发流体看起来像从塔中升起的烟雾，但整个堆积物更正式的名字是块状硫化物矿床。
