Stony-iron meteorites are all differentiated, meaning that they show signs of alteration. Scientists have divided these meteorites into three main types: stony, iron, and stony-iron. This distinguishes them from the stony meteorites, that are mostly silicates, and the iron meteorites, that are mostly meteoric iron. Types of Meteorites More than 60,000 meteorites have been found on Earth. It weighs in at a whopping 3780 grams/8.3 lbs. Stony-iron meteorites or siderolites are meteorites that consist of nearly equal parts of meteoric iron and silicates. This exceptionally large and well preserved stony meteorite is a rare and fantastic find. Most of our stony meteorites are found in the Sahara desert in Morocco, and along the Algerian border.

One of the most prominent characteristics of stony meteorites is, "Fusion crust" this crust, usually black, forms as a result of friction and ablation caused by the intense cosmic velocity, which these meteorites experience during passage through Earth's atmosphere. Achondrites, which consist of stony-irons, and irons were formed by melting, either on or deep within a planetary parent body.Īchondrites include asteroidal chondrites, and Martian rocks. These four categories can be further subdivided, but we will skip that to keep things simple. Chondrites can be further subdivided into four categories: Ordinary chondrites, Carbonaceous chondrites,R-Chondrites, and E-Chondrites.

Stony Meteorites are broken up in two major classes, Chondrites, and achondrites. Irons and stony-irons require equipment or labor really beyond what the collector probably wants to invest. The remaining minerals are commonly referred to as accessory minerals, and they only make up about 10-15% of the total weight. Pyroxenes make up about 15 to 25%, and third, nickel-iron metal with about 3-23% by weight. Between the three major minerals that make up the common stony meteorites, Olivine usually takes up 40 to 50%. Olivine and pyroxenes are the most abundant minerals in stony meteorites. Stony meteorites, while not as iron/nickel rich as the other types, still have enough magnetism for a strong magnet to attach. Stony meteorites are comprised of three primary minerals, Olivines, Pyroxenes, and Nickel-Iron Minerals.
