Stony Meteorite :
Stony meteorites are one of the most abundant meteorite types, consisting largely of silicate minerals, divided into two groups named chondrites and achondrites.
Stony meteorites are primarily composed of silicates, but up to 25% of their mass can come from iron and nickel.
STONY METEORITE - Meteorite composed of silicate minerals, but that may have up to 25% Ni-Fe metal by weight.
a stony meteorite containing small, round, silicate granules called chondrules

A stony meteorite, composed primarily of silicates. About 93 percent of all known falls are aerolites. They include the carbonaceous chondrites, other chondrites, and achondrites. (lit. "air stone.")

A type of stony meteorite that contains numerous small spherules of silicate (silica, silicon dioxide) minerals. A subset of this type of meteorites, the carbonaceous chondrites, contains several per cent organic carbon.

chondrite -- A stony meteorite, composed of finely crystallized material.
coma -- A roughly spherical region of diffuse gas which surrounds the nucleus of a comet. Together, the coma and the nucleus form the comet's head.
Achondrite
a stony meteorite representing differentiated planetary material.
Chondrites are stony meteorites that have not been modified due to melting or differentiation of the parent body.

Christopher Chyba and others have proposed a process whereby a stony meteorite could have exhibited the behavior of the Tunguska impactor.
CARBONACEOUS CHONDRITE - Rare type of stony meteorite, carbonaceous chondrites are the most primitive and unaltered type of meteorite known, with elemental compositions probably similar to that of the nebula from which the Solar System formed.
Chondrite: An abundant class of stony meteorites with chemical compositions similar to that of the Sun and characterized by the presence of chondrules (see definition below).
The rarer of the two main types of stony meteorite, accounting for about 9% of all meteorite falls. Achondrites are made of rock that has crystallized from a molten state.
The most common meteorites are chondrites, which are stony meteorites. Radiometric dating of chondrites has placed them at the age of 4.55 billion years, which is the approximate age of the solar system.
(Chondrites, the most common type of stony meteorite, are so called because they contain small primordial silicate spherules known as chondrules.) Ages measured by the decay of potassium to argon show that this shock metamorphism took place quite ...
Stony meteorites are further classified as chondrites, achondrites, or carbonaceous chondrites based on their carbon content and texture.

20 (a) A stony meteorite often has a dark fusion crust, created when its surface is melted by the tremendous heat generated during passage through the atmosphere. (b) Iron meteorites, much rarer than stony ones, usually contain some nickel as well.
They are of different types, Stony meteorites, iron meteorites and the rare carbonaceous chondrites.
Three-quarters of the asteroids visible from earth, including Ceres, belong to the C type, which appear to be related to a class of stony meteorites known as carbonaceous chondrites.
Meteorites have traditionally been divided into three broad categories: stony meteorites are rocks, mainly composed of silicate minerals; iron meteorites are largely composed of metallic iron-nickel; and, ...
The aerolites, or stony meteorites, show a diversity of mineral elements including large percentages of silicon and magnesium oxides; the most abundant type of aerolite is the chondrite, ...
Big Manitoba Meteorite. A retired Canadian farmer discovered the second largest stony meteorite ever found in Canada in 1997 while operating a road grader. The Elm Creek meteorite was the largest ever found in Manitoba.
ACHONDRITIC METEORITE
An achondritic meteorite is a stony meteorite, coarsely crystallized, with large bits of various minerals visible to the naked eye.

A preliminary analysis of asteroid samples returned last year by Japan's Hayabusa probe show evidence the dust grains have a similar composition to stony meteorites that commonly fall to Earth.
Most meteoroids burn up completely in the atmosphere but occasionally one survives to actually hit the Earth. This object is then termed a meteorite. Meteorites are subdivided into two main categories: stones (stony meteorites) and irons ...
