The battle between these forces strains the third factor: 这场力的较量 会作用在第三个因素上: the rock strength of the Earth’s crust. 地壳的岩石强度。 Usually, the rock is strong enough and heavy enough 通常,岩石足够坚固、沉重, to keep the magma in place. 可以让岩浆保持在原位。 But whe...

Magma: Magma is found below the surface of the Earth, often collecting in chambers below volcanoes and deep in the crust near the mantle. It is extremely hot. When magma reaches the surface of the Earth through volcanic vents, it is called lava. ...
This introductory chapter provides a broad overview of magma mixing processes in the volcanic and plutonic environments. The structural, textural and geochemical evidence for magma mixing is briefly discussed, with the aim to provide a general picture about this fundamental, yet relatively poorly known...
(source: Wikipedia). Indeed, the Magma Wyrms share similarities in appearance to crocodiles. Their scales, for example, are rock solid and resemble those of crocodiles. The same goes for the way they crawl on the ground. However, the part that doesn’t fit is how the “Makara” in ...
Hamilton’s quaternion number system is a non-commutative extension of the complex numbers, consisting of numbers of the form where are real numbers, and are anti-commuting square roots of with , , . While they are non-commutative, they do keep many other properties of the complex numbers: ...
The largest maars in the world are the Espenberg Maars on the Seward Peninsula of Alaska. These maars are up to 8000 meters across and up to 300 meters in depth. They were formed during the Pleistocene when ascending basaltic magma encountered frozen permafrost. It is believed that a slow ...
project, combining the efforts of professional and amateur mathematicians, automatic theorem provers, AI tools, and the proof assistant language Lean, to describe the implication graph relating the 4694 equational laws for magmas that can be expressed using up to four invocations of the magma ...
While kimberlite is the most common source of diamonds, finding it doesn’t guarantee finding diamonds. In fact, few kimberlite pipes actually prove worthwhile to pursue. Miners determine if a kimberlite pipe is worth pursuing by conducting regional sampling schemes and airborne geophysical surveys in...
