پنتلاندیت
Sign in to savethumb|Pentlandite in pyrrhotite, ore specimen from the [[Sudbury Basin (field of view 3.4 cm)|300x300px]] Pentlandite is an iron–nickel sulfide with the chemical formula . Pentlandite has a narrow variation range in nickel to iron ratios (Ni:Fe), but it is usually described as 1:1. In some cases, this ratio is skewed by the presence of pyrrhotite inclusions. It also contains minor cobalt, usually at low levels as a fraction of weight.
