Chondras in the body of a meteorite. In the context.
Chondras (from other Greek: χόνδρος - grain ) are rounded formations with an average size of 0.5-1.0 mm , which are the main structural element of 90% of meteorites called chondrites . These are rapidly solidified drops of molten silicate. They are classified into three types:
- eccentric radiant;
- grate;
- microporphic.
There are various hypotheses regarding their formation, some of them:
- are formed as a result of a sharp temperature drop when a meteorite enters the dense layers of the earth's atmosphere .
- are formed directly from the protoplanetary cloud surrounding and surrounding the Sun by condensation of matter and accretion of dust with intermediate heating.
