Zaklodzie meteorite 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 Zaklodzie meteorite rather than just read about it. In short: The Zakłodzie meteorite is a stony-iron meteorite found in Poland in 1998. Its mass is 8.68 kilograms (19.1 lb).

Key takeaways

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

Reference excerpt

The Zakłodzie meteorite is a stony-iron meteorite found in Poland in 1998. Its mass is 8.68 kilograms (19.1 lb). It is composed predominantly from enstatite and meteoric iron. Currently classified as an ungrouped enstatite achondrite its classification is still an ongoing scientific debate.

Naming and history The Zakłodzie meteorite was found beside a dirt road by Stanisław Jachymek who was searching for fossils and rocks. The site lies south of the village Zakłodzie (Lublin Voivodeship), after which the meteorite is named. A fireball, which may well have been the Zakłodzie meteorite, was seen in the area of the find on 21 April 1897; its weathering is consistent with such an age. As of 20 December 2012 part slices were on sale at US$100/g.

Mineralogy The meteorite is composed of 60% orthoenstatite, 20% meteoric iron, 10% troilite and 10% feldspar. Accessory minerals include schreibersite, oldhamite, alabandite, keilite and amphibole. The meteoric iron has a Nickel content of 16%. The mineral composition is similar to an enstatite chondrite with strongly metamorphosed chondrules. A second interpretation is that the textures are a result of cumulate crystallization or an impact-melt breccia. It's the type locality of two minerals: browneite (IMA 2012-008) and buseckite (IMA 2011-070).

Classification The meteorite was classified as an "ungrouped enstatite-rich meteorite" in 2000. In 2005 it was proposed that the meteorite was the product of magma crystallization and therefore an achondrite. The magma originated from the partial melt of an enstatite chondrite source. It was therefore proposed that the Zakłodzie meteorite should be classified as a "primitive enstatite achondrite". It was classified as an Aubrite-an (anomalous) in 2006. Currently the recommended classification is that the Zakłodzie meteorite is an ungrouped enstatite achondrite. Some scientists propose that many aubrites and enstatite achondrites are in fact impact breccias or impact-melt breccias. The later being proposed for Zakłodzie and NWA 4301. The main arguments for this hypothesis are the relics of chondrules, the euhedral enstatites surrounded by meteoric iron and the occurrence of keilite. Keilite is possibly a product of reactions that take place when enstatite achondrites are melted and quenched (a quick decrease in temperature). This could happen during impact events on the surface of the parent body.

Worked examples

Example 1 — a first encounter with Zaklodzie meteorite

Start with the simplest possible case. Write down what Zaklodzie meteorite 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 Zaklodzie meteorite 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 Zaklodzie meteorite 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 Zaklodzie meteorite

In research: Zaklodzie meteorite 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 Zaklodzie meteorite 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: Zaklodzie meteorite is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1998 in Poland, Achondrite meteorites, Meteorites found in Poland, so understanding it makes those chapters shorter.
In everyday life: Look for Zaklodzie meteorite 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.
