Stone -iron meteorites, formerly called Siderolithe make, with about five percent only a small fraction of all meteorites. They are, as the name suggests, a mixture of silicate minerals and the characteristic of iron meteorites iron -nickel alloy. They will continue in

Divided.

Inside the Pallasites you find cm - large, yellowish green magnesium - rich olivine crystals embedded in a metallic host matrix. Typically, the ratio of olivine and metal is about one to two. At still higher metal content observed even in the iron meteorite Widmanstatten structures occur. They probably originate from the border zone between the shell and the olivine dominated by iron and nickel core former asteroids. The other stone -iron meteorites have complex structures and compositions.
