A bronze-colored mineral, of metallic luster. It is a sulphide of iron, and is remarkable for being attracted by the magnet. Called also magnetic pyrites.
A yellow-tan iron sulfide mineral, approximately FeS.
Yellow-brown, reddish, occasionally somewhat magnetic mineral composed of iron and sulfur. It sometimes contains nickel and is mined for its nickel content.
a common red to brown sulphide mineral.
a brownish iron sulfide mineral FeS having weak magnetic properties
FeS, an iron sulfide mineral.
Means the mineral pyrrhotite (FeS) Means tonnes (metric system of measurements). Means tons (imperial system of measurements).
A bronzed-colored, magnetic iron sulphide mineral, a high- temperature relative of pyrite.
A sulphide mineral of iron, FeS. rock chip sampling The collection of representative samples of rock fragments within a limited area.
A bronze-coloured, magnetic iron sulphide mineral. Quartz (SiO2): Common rock-forming mineral consisting of silicon and oxygen. Rhyolite: Any of a group of felsic extrusive rocks which have the same chemical composition as granite. Rock: Any natural combination of minerals.
a native iron sulfide having a reddish-brown to bronze color and a metallic luster, occurring in crystals and masses. It often contains nickel and is usually slightly magnetic. [AHDOS
Pyrrhotite is an unusual iron sulfide mineral with a variable iron content: Fe(1-x)S (x = 0 to 0.2). The FeS endmember is known as troilite. Also called magnetic pyrite because the color is similar to pyrite and it is weakly magnetic, the magnetism increases as the iron content decreases.
