Tamdakht meteorite

Tamdakht 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 Tamdakht meteorite rather than just read about it. In short: The Tamdakht meteorite fell near Ouarzazate, Morocco on 20 December 2008 producing a strewn field of approximately 25 kilometres (16 mi) by 2 kilometres (1.2 mi) and two small impact craters, one of about 1.1 metres (3 ft 7 in) diameter and 70 centimetres (28 in) depth at 31°09.8′N 7°00.9′W and the other of about 20 centimetres (7.9 in) diameter and 10 centimetres (3.9 in) depth at 31°09.9′N 07°02.3′W. The meteorite…

Key takeaways

Tamdakht 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 Tamdakht meteorite to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tamdakht meteorite from memory before moving on to harder problems.

Reference excerpt

The Tamdakht meteorite fell near Ouarzazate, Morocco on 20 December 2008 producing a strewn field of approximately 25 kilometres (16 mi) by 2 kilometres (1.2 mi) and two small impact craters, one of about 1.1 metres (3 ft 7 in) diameter and 70 centimetres (28 in) depth at 31°09.8′N 7°00.9′W and the other of about 20 centimetres (7.9 in) diameter and 10 centimetres (3.9 in) depth at 31°09.9′N 07°02.3′W. The meteorite is named after a village close to the fall. On April 22, 2017, small bits of the meteorite were handed out to children at the Boston March for Science.

Mineralogy Petrology: (by Albert Jambon, Omar Boudouma, D. Badia UPVI and M. Denise, MNHNP): Abundant chondrules with visible but not well-delimited outlines. Chondrule size is 0.1 to 1.5 mm. Dominant olivine and orthopyroxene. Abundant chromite, rare clinopyroxene and ilmenite. Numerous pockets with chromite, plagioclase and phosphate (merrilite and Cl-apatite). Kamacite, with deformed Neumann bands, and taenite, twinned troilite. Copper. Mode: metal+troilite 10%. Mineral compositions and geochemistry: log χ = 5.3. Olivine Fa18 ± 0.5 Opx = En83 Fs16 Wo2 Minor calcic pyroxene. Plagioclase is Ab83–86 An5–15 Or7–2. Ca-phosphate (merrillite and Cl-apatite). Chromite: Cr# (100× molar Cr/[Cr + Al]) = 82. Metal: kamacite with 5% Ni and taenite with 36–47% Ni. Oxygen isotopes (C. Suavet, J. Gattacecca CEREGE): δ17O = 3.26‰, δ18O = 5.01‰, and Δ17O = 0.65‰. Magnetic susceptibility is log χ = 5.3 × 10–9 m3/kg.

Classification Ordinary chondrite (H5), S3, W0.

Other In 2016, the Cook Islands issued a collector coin in which a piece of the meteorite is embedded.

Worked examples

Example 1 — a first encounter with Tamdakht meteorite

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

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