Phosphosiderite is a type of iron phosphate found only in a few locations worldwide.
Iron phosphate is a chemical compound of iron and phosphate. Iron is a metal, and phosphate is a group of atoms containing phosphorus and oxygen.
When both come together, they form iron phosphate.
Phosphosiderite was once known as metastrengite, but this name is no longer used.
Although phosphosiderite forms very small crystals in shades of red and pink, it's found more often with a crystal habit known as 'massive'.
Minerals with a massive crystal habit form crystals that grow so tightly together they form one large, shapeless mass.
