Tlalocite

Tlalocite is a earth 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 Tlalocite rather than just read about it. In short: Tlalocite is a rare and complex tellurate mineral with the formula Cu10Zn6(TeO4)2(TeO3)(OH)25Cl · 27 H2O. It has a Mohs hardness of 1, and a cyan color.

Key takeaways

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

Reference excerpt

Tlalocite is a rare and complex tellurate mineral with the formula Cu10Zn6(TeO4)2(TeO3)(OH)25Cl · 27 H2O. It has a Mohs hardness of 1, and a cyan color. It was named after Tlaloc, the Aztec god of rain, in allusion to the high amount of water contained within the crystal structure. It is not to be confused with quetzalcoatlite, which often looks similar in color and habit.

Occurrence Tlalocite was first identified in the Bambollite mine (La Oriental), Moctezuma, Municipio de Moctezuma, Sonora, Mexico and it was approved by the IMA in 1974. It often occurs together with tenorite, azurite, malachite and tlapallite. It is found in partially oxidized portions of tellurium-bearing hydrothermal veins.

Worked examples

Example 1 — a first encounter with Tlalocite

Start with the simplest possible case. Write down what Tlalocite 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 Tlalocite 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 Tlalocite 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 Tlalocite

In research: Tlalocite 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 Tlalocite 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: Tlalocite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Copper(II) minerals, Hydrate minerals, Mineral stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Tlalocite 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.

Frequently asked questions

What is Tlalocite in simple terms?

Tlalocite is a rare and complex tellurate mineral with the formula Cu10Zn6(TeO4)2(TeO3)(OH)25Cl · 27 H2O. It has a Mohs hardness of 1, and a cyan color.

Why does Tlalocite matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Tlalocite?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
