[quote:Anonymous Coward 79479031:MV80OTMxMzAwXzkwMTM4MjU2X0ZFNTU2NzU=] [quote:Anonymous Coward 79479031:MV80OTMxMzAwXzkwMTM4MjIwX0E5Qzc2NTg3] [quote:Anonymous Coward 81002935:MV80OTMxMzAwXzkwMTM4MDk3X0Q3RDNGRDgx] [quote:Anonymous Coward 81002935:MV80OTMxMzAwXzkwMTM4MDQ0X0ZCNzREMjc2] I was thinking heavy mineral sands. But am not sure they're magnetic like that. https://en.wikipedia.org/wiki/Heavy_mineral_sands_ore_deposits [/quote] Just following up. Magnetite is often part of heavy mineral sands. Magnetic separation is often used to separate the heavy minerals from quarts. https://faculty.uml.edu/Nelson_Eby/Forensic%20Geology/Exercises/Heavy%20Minerals%20and%20Magnetic%20Separation.pdf [quote:Study]The simplest form of magnetic separation is by hand magnet, a procedure which works for only one common mineral - magnetite. Other minerals having magnetic susceptibility are separated by using an apparatus that can generate strong electromagnetic fields.[/quote] Not saying one way or another, but those ladies could possibly have just "discovered" magnetite-laden heavy mineral sands and then did a textbook method of hand separating them.

Watch this. Look how it grows and attaches to her hand (which isn't a magnet.) How did this get on the sand? Has it come off jabbed people? Been sprayed?
