火山口

Other rocks are breccias — crushed and broken rock fragments, fused by the heat from impact collisions and ejected from the resulting crater.

其他岩石是角砾岩——由粉碎和破碎的岩石碎片，经挤压的高温融化并在火山口喷发出来。

The caldera wall sequences are up to 0.6km thick and consist of lavas with 51-69 percent SiO2 and 0.2-5 percent MgO as well as breccias, dikes, sills, domes and minor ignimbrites.

火山口壁序列均达到0.6公里厚的熔岩组成，SiO2和0.2-5 51-69百分之百分之氧化镁以及角砾岩，堤防，窗台，圆顶和次要ignimbrites。

A series of collapse cr at er s, or calderas, lie at its summit.

其顶端有一系列崩塌的火山口，或称火山臼。

These impact points stirred up subterranean waters and minerals, turning the calderas into life-filled pockets on the planet's surface.

这些陨石撞击影响了地下水以及矿脉，使得火山口成为地表上孕育生命的地方。

The distribution and formation of epithermal gold deposits in northern Xinjiang are structurally controlled by calderas, craters, diatremes and related faults.

金矿的形成和分布受破火山口、隐爆角砾岩筒、与火山机构有关的断裂以及区域断裂控制。

Before the West Coast of the US starts adjusting to the new position of Mexico, with slip-slide adjustments, there will be a bending of the Arizona desert area that will fracture the dry soil, create a breach in the great Colorado River dam, and allow magma to rise in the calderas in the US - Mammoth Lake in California and Yellowstone.

在美国西海岸把位置调整到墨西哥的新位置，进行滑动调整之前，亚利桑那州沙漠地区将会破裂，使干燥的土地开裂，造成科罗拉多州大坝的崩裂，让美国巨火山口处的岩浆涌出来-----即马姆莫斯湖和黄石火山。

The epithermal gold deposits in East China can be divided into low-sulfidation and high-sulfidation types, which are related to granitic and alkaline series magmatic rocks.

这些金矿的形成和分布受区域构造制约，具体地说是受破火山口、火山角砾岩筒以及与火山机构有关的断裂控制。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
