Potassic-magnesio-fluoro-arfvedsonite

Potassic-magnesio-fluoro-arfvedsonite is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Potassic-magnesio-fluoro-arfvedsonite rather than just read about it. In short: Potassic-magnesio-fluoro-arfvedsonite is an amphibole mineral first discovered in Quebec, Canada, in an area which is part of the Canadian Shield which is where some of the oldest exposed rocks are that can date back to over 4 billion years ago. Potassic-magnesio-fluoro-arfvedsonite is also the mineral with the longest name of any mineral with 34 letters and 37 characters.

Key takeaways

Potassic-magnesio-fluoro-arfvedsonite belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Potassic-magnesio-fluoro-arfvedsonite to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Potassic-magnesio-fluoro-arfvedsonite from memory before moving on to harder problems.

Reference excerpt

Potassic-magnesio-fluoro-arfvedsonite is an amphibole mineral first discovered in Quebec, Canada, in an area which is part of the Canadian Shield which is where some of the oldest exposed rocks are that can date back to over 4 billion years ago. Potassic-magnesio-fluoro-arfvedsonite is also the mineral with the longest name of any mineral with 34 letters and 37 characters.

Occurrence Potassic-magnesio-fluoro-arfvedsonite is found in igneous rocks. The rocks it is found in are classified as a complex mafic ultrapotassic peralkaline igneous rock with high silica contents. Most commonly it is found with Lamproite. Potassic-magnesio-fluoro-arfvedsonite is a uniquely rare mineral, as it occurs in small amounts in very few locations around the world.

Physical properties Potassic-magnesio-fluoro-arfvedsonite is a bluish-gray mineral with a vitreous luster. It exhibits a hardness of 6 on the Mohs hardness scale. It leaves a white streak of powder behind when you rub it against another surface. Potassic-magnesio-fluoro-arfvedsonite shows perfect cleavage along the {110} plane. The calculated density is 3.174 g/cm3.

Age Potassic-magnesio-fluoro-arfvedsonite has only been found in a handful of regions. These regions are Quebec, Canada, Montepuez District, Mozambique, Troms Og Finnmark, Norway, Dakhla-Oued Ed-Dahab. Morocco, and Las Vegas, USA. One thing all these locations have in common is the rock formations are older rocks that range from the late Archean eon to the Proterozoic. This range goes from around 2.5 billion years ago to 538 million years ago.

Name When potassic-magnesio-fluoro-arfevdsonite was first discovered in Quebec in 1985 it was named Potassium fluor-magnesio-arfvedsonite. It was seen as a potassium rich fluor-magnesio-arfvedsonite (now renamed magnesio-fluoro-arfvedsonite). In 2006 it was renamed by the IMA as fluoro-potassic-magnesio-arfvedsonite. and later in 2012 it was renamed again as potassic-magnesio-fluoro-arfvedsonite. It has this name as it is an arfvedsonite that has magnesium, potassium, and fluorine. Potassic-magnesio-fluoro-arfvedsonite has 37 characters which is the longest for any approved mineral.

Chemical composition

X-ray diffraction and Crystallography

The X ray diffraction of potassic-magnesio-fluoro-arfevsonite gave values of the chart above.

Worked examples

Example 1 — a first encounter with Potassic-magnesio-fluoro-arfvedsonite

Start with the simplest possible case. Write down what Potassic-magnesio-fluoro-arfvedsonite claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Potassic-magnesio-fluoro-arfvedsonite 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 Potassic-magnesio-fluoro-arfvedsonite 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 Potassic-magnesio-fluoro-arfvedsonite

In research: Potassic-magnesio-fluoro-arfvedsonite appears in 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 Potassic-magnesio-fluoro-arfvedsonite 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: Potassic-magnesio-fluoro-arfvedsonite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibole group, so understanding it makes those chapters shorter.
In everyday life: Look for Potassic-magnesio-fluoro-arfvedsonite 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.
