A Hilarious Chemistry Joke about Magnesium Iron Silicate Hydroxide!

Magnesium Iron Silicate Hydroxide (abbreviated as MISH) is a metamorphic amphibole with the chemical composition (Mg, Fe2+)2 (Mg, Fe2+)5 Si8 O22 (OH)2.

It looks like this:

Thus we can see that it has a dark green, brown, gray, beige; colorless to pale green in thin section. Its diagnostic features are: It is characterized by light brown color and needlelike, often radiating habit. MISH is difficult to distinguish from anthophyllite or gedrite without optical and/or X-ray tests.

Monoclinic MISH is compositionally similar and polymorphic with orthorhombic anthophyllite, which is a much more common form of magnesium-rich amphibole, the latter being metastable.

Cummingtonite shares few compositional similarities with alkali amphiboles such as arfvedsonite, glaucophane-riebeckite.

There is little solubility between these minerals due to different crystal habit and inability of substitution between alkali elements and ferro-magnesian elements within the amphibole structure.

Magnesium Iron Silicate Hydroxide is commonly called as Cummingtonite:

Why the vulgar name, you ask? Cummingtonite was named after the town of Cummington, Massachusetts, where it was discovered in 1824:

A nice story for you:

Bob and Alice are a married couple living in Glendale, Arizona. Bob is a geologist at an university and Alice is a middle school English teacher.

One summer Bob goes to the state of Massachusetts to examine ores and mining practices on behalf of the government. At work on Monday, Bob is busy at mining sites at a particular town. Alice calls him and asks "Honey, where are you and what're you doing?"

Bob answers, "I can't talk now honey as I'm busy working with Cummingtonite in Cummington! See you in a month!" and hangs up the phone.

Alice cannot believe what she just heard! Furious, she calls him up again and Bob is in trouble through no fault of his own. They talk for hours on the phone! Geology as a career proved a deadly choice for Bob!
