STONY-IRON METEORITE - Meteorite composed of roughly equal amounts by weight of silicate minerals and Ni-Fe metal. The stony-irons consist of two groups: mesosiderites and pallasites.
stony-iron meteorite: A meteorite that is a mixture of stone and iron.
stromatolite: A layered fossil formation caused by ancient mats of algae or bacteria that build up mineral deposits season after season.
Stony-iron Meteorite - A meteorite made partially of stone and partially of iron and other metals
Stratosphere - The region of the atmosphere of a planet immediately above the troposphere ...
Stony-iron meteorites constitute the remaining 1%. They are a mixture of iron-nickel metal and silicate minerals. One type, called pallasites, is thought to have originated in the boundary zone above the core regions where iron meteorites originated.
Pallasite
a stony-iron meteorite in which nodules of olivine (a silicate mineral) are surrounded by a network of iron-nickel metal.
Parallax
the apparent change in position of two objects viewed from different locations.
K- and S-class asteroids have moderate albedos and spectral reflectances similar to the stony-iron meteorites, and they are known to contain significant amounts of silicates and metals, including the minerals olivine and pyroxene on their surfaces.
Mesosiderite: A class of stony-iron meteorites consisting of metal and fragments of igneous rocks. These meteorites formed as breccias, but most have been recrystallized during metamorphism.
the solar magnetic field as it passed by Ida (a similar effect was found at Gaspra). This indicates the Ida must contain some magnetic material, though its density is far too low for it to be similar in composition to an iron or stony-iron meteorite.
There are three types of meteorites - stony, iron, and stony-iron meteorites - and they range in size from microscopic to the size of an asteroid. Several hundred tons of meteoric material are estimated to fall on the earth each day. [SILK90] ...
Stony-iron meteorites are roughly equal parts silicate and iron-nickel by mass. They account for only about 1% of the meteorites known to have fallen to Earth and also originate from differentiated asteroids.
