Common Chondrite

Common chondrites, also known as ordinary chondrites, are the most abundant type of meteorite found on Earth. They are ancient stony objects that formed within the solar disc about 4.5 billion years ago and which are by far the most frequently discovered "space rocks." Many of these are found in large "strewnfields" in the North Western Sahara. While waiting for a full examination/description, they are referred to as unclassified NWA Meteorites (North West Africa Meteorites).  

These meteorites are composed primarily of silicate minerals, such as olivine and pyroxene, along with small amounts of iron-nickel metal. They are characterized by the presence of chondrules, which are small, spherical grains of silicate minerals that formed as molten droplets in the early solar system. Common chondrites are further classified into three main groups: H chondrites (high iron), L chondrites (low iron), and LL chondrites (low iron, low metal). These groups differ in their overall iron content and the amount of iron present as metal versus iron oxide.
