Meteorites are "rocks", not from Earth, but from somewhere else in the solar system. Because they contain some of the same mineralogy - plagioclase, pyroxene, olivine, etc., weathering can cause most that have been here for a while to look like Earth rocks. Similarly, the weathering of Earth rocks can make some resemble meteorites.
If rocks are buried deep enough, they melt. When the rock material is molten, it is called a magma. If the magma moves upward toward the surface it cools and crystallizes to form igneous rocks. This whole process is called the Rock Cycle. [ Return to Rock Key Table of Contents]
Answer. A1. Platinum can occur in many forms in nature. The platinum group elements (platinum, palladium, rhodium, ruthenium, iridium and osmium) generally occur as alloys with iron or with transition group metals such as arsenic, tellurium, antimony and vanadium; or as mixed platinum-palladium sulphide minerals (cooperite and braggite).
