Non Magnetic Meteorite Identification Pictures: A Comprehensive Guide

As an amateur rockhound or enthusiast of celestial bodies, identifying meteorites can be a thrilling experience. However, the process requires careful observation and attention to detail. In this article, we will provide you with a comprehensive guide on how to identify non-magnetic meteorites using pictures.

Desert Varnish: A Common Mimicry

If you found your rock in a desert environment, it's essential to consider whether its black surface might be desert varnish. Rocks in the desert often develop a shiny black exterior that resembles fusion crust, making it challenging to distinguish between the two. The fusion crust may appear like a black eggshell coating the rock.

Lack of Magnetic Anomalies

Non-magnetic meteorites are characterized by their lack of magnetic anomalies. If your rock does not exhibit any magnetic properties, it is most likely not a meteorite. This is because most meteorites contain iron and nickel, which are naturally magnetized.

Types of Meteorites

There are three main types of meteorites: stony meteorites, stony-iron meteorites, and iron meteorites. Stony meteorites are primarily composed of silicate minerals, while stony-iron meteorites have nearly equal amounts of metal and silicate crystals. Iron meteorites, on the other hand, are almost completely made of metal.

Fusion Crust: A Key Indicator

A fusion crust is a featureless, melt-like surface that forms when rocks pass through the Earth's atmosphere. It can include ripple marks and 'droplets' where molten stone had moved and resolidified. If your rock has a smooth, featureless surface with these characteristics, it may be a meteorite.

Desert Varnish vs. Fusion Crust

To distinguish between desert varnish and fusion crust, look for the following features:

* Desert varnish often develops on rocks that have been exposed to the elements for an extended period.

* Fusion crust is typically smooth and featureless, with ripple marks and 'droplets' where molten stone had moved and resolidified.

In conclusion, identifying non-magnetic meteorites requires a combination of observation skills, knowledge of meteorite types, and attention to detail. By considering the characteristics of desert varnish, fusion crust, and magnetic anomalies, you can increase your chances of correctly identifying a non-magnetic meteorite. Remember to consult with experts and reputable sources if you're unsure about the authenticity of your find.
