    Platinum can occur as a native metal, but it can also occur in various different minerals and alloys. [16] [17] That said, Sperrylite (platinum arsenide, PtAs 2) ore is by far the most significant source of this metal. [18] A naturally occurring platinum-iridium alloy, platiniridium, is found in the mineral cooperite (platinum sulfide, PtS).

    The largest grouping of minerals by far are the silicates; most rocks are composed of greater than 95% silicate minerals, and over 90% of the Earth's crust is composed of these minerals. [102] The two main constituents of silicates are silicon and oxygen, which are the two most abundant elements in the Earth's crust.
