1. Bullet-shaped directional meteorites (as shown in Figure 1 and Figure 2) are characterized by the fact that the individual is generally not too big, bullet-shaped, with obvious melting lines and curling edges. Without good protective measures, the melting line of meteorites will be oxidized in the wild, and it will become shallow or even disappear with the passage of time.
Secondly, the nail-shaped meteorite (as shown in Figure 3 and Figure 4, directional meteorite) is characterized by obvious fuse and curl of rivets. Without good protective measures, the melting line of meteorites will be oxidized in the wild, and it will become shallow or even disappear with the passage of time.
3. Button-shaped (Figure 5, Figure 6) The button-shaped directional meteorite is characterized by buttons, a bulge at the back end, and obvious melting and curling. There may be a boiling molten shell on the edge of the stone meteorite (Figure 7). Without good protective measures, the melting line and boiling shell of meteorites will be oxidized in the wild, and will become shallow or even disappear with the passage of time.
4. Toothpick-shaped (as shown in Figure 8) Toothpick-shaped meteorites are characterized by toothpicks. Some meteorite lovers say that they are like earthworms, thin and long, with obvious melting lines. In the wild, the melting line of meteorites will be oxidized, and the melting line will become shallow or even disappear with time.
Fifth, there is little difference between shield-shaped meteorites (Figure 9) and button-shaped meteorites. Button-shaped meteorites have raised tails, while shield-shaped meteorites have flat tails with melting lines and curling edges, and some even have boiling molten shells. The definition of curling of all directional meteorites depends on the length of directional time, and the longer the directional time, the more obvious the curling will be.
Thank Mr. Yang Guang for providing meteorite pictures to promote meteorite knowledge.
