Reference excerpt

Large-volume volcanic eruptions in the Basin and Range Province include Basin and Range eruptions in Utah, California, Idaho, Colorado, New Mexico, Texas, Arizona, Nevada, Wyoming, and Oregon, as well as those of the Long Valley Caldera geological province and the Yellowstone hotspot.

Volcanic fields The volcanic fields within the Basin and Range Province include Northwestern Nevada, the Modoc Plateau, Central Nevada, the Great Basin, Southwestern Nevada, the Mojave Desert, and the Long Valley Caldera regions. Named fields include Coso Volcanic Field, Mono Lake Volcanic Field, Marysvale Volcanic Field, San Juan volcanic field, Indian Peak, Central Colorado volcanic field, Jemez volcanic lineament, Mogollon-Datil volcanic field, Santa Rosa-Calico, and Boot Heel volcanic field.

Geological features Many geological features in Western United States have a Northeastern orientation; the North American craton motion has the same orientation as well. For example: the Trans-Challis fault zone in Idaho, the Snake River in Oregon, the Garlock Fault in California, the Colorado River in Utah, the Colorado Mineral Belt, Crater Flat-Reveille Range-Lunar Crater lineament, the Northwestern Nevada volcanic field, the San Juan caldera cluster in Colorado, the Socorro-Magdalena caldera cluster in New Mexico, Jemez Lineament, and the Yellowstone hotspot trail. But the Yellowstone hotspot trail was modified through faults and extension.

Geology Prior to the Eocene Epoch (55.8 ± 0.2 to 33.9 ± 0.1 Ma), the convergence rate of the Farallon and North American Plates was fast and the angle of subduction was shallow. During the Eocene, the Farallon Plate subduction-associated compressive forces of the Laramide orogeny ended, plate interactions changed from orthogonal compression to oblique strike-slip, and volcanism in the Basin and Range Province flared up. It is suggested that this plate continued to be underthrust until about 19 Ma, at which time it was completely consumed and volcanic activity ceased, in part. Olivine basalt from the oceanic ridge erupted around 17 Ma and extension began. The extension resulted in roughly north-south-trending faults, the Great Basin, the Walker trough, the Owens graben, and the Rio Grande rift, for instance.

Worked examples

Example 1 — a first encounter with List of large-volume volcanic eruptions in the Basin and Range Province

Start with the simplest possible case. Write down what List of large-volume volcanic eruptions in the Basin and Range Province claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of large-volume volcanic eruptions in the Basin and Range Province before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of large-volume volcanic eruptions in the Basin and Range Province ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of large-volume volcanic eruptions in the Basin and Range Province

In research: List of large-volume volcanic eruptions in the Basin and Range Province appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of large-volume volcanic eruptions in the Basin and Range Province in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of large-volume volcanic eruptions in the Basin and Range Province is common in secondary-school and first-year university syllabi. It links to neighbouring topics Basin and Range Province, Calderas of the United States, Cenozoic volcanism, so understanding it makes those chapters shorter.
In everyday life: Look for List of large-volume volcanic eruptions in the Basin and Range Province outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
