There's no way to answer your question. More accurately, there is no way to answer your question without sounding like a smart-ass. We can't tell which has more mass unless we know how much of each you have to begin with! If you've got a pound of quartz and 10 pounds of pyrite, the pyrite is more massive, because objects with greater mass have greater weight. If you've got only an ounce of pyrite, your one-pound sample of quartz is more massive. Here's a question for you: What weighs more, a pound of feathers or a pound of rocks? Many people who answer too quickly say, "Rocks." And they'd be wrong. Since both weigh a pound, they have the same weight and, therefore, have the same mass. In other words, they both contain the same amount of matter. Perhaps what you meant to ask is What has the greater density? Density is mass per unit volume. So, if you had, say, a cubic foot of quartz and a cubic foot of pyrite, then you could ask Which is more massive? or Which has greater mass? That would be a question we could answer definitively. Quartz has a density of about 2.65 grams per cubic centimeter. Pyrite's density is about 4.9 g/cc. So a cubic centimeter of pyrite is more massive than a cc of quartz.
the density of pyrite or fool's gold is 5.01g/cm3
Pyrite has the property fracture. - Raymond Cheung
Pyrite is FeS2, an iron sulfide.
Pyrite
Because of the pressure and time used to create natural pyrite, more crystals develop, giving it that shiny, crystalline look, whereas man made is created in such a short amount of time that there isn't a lot of gold, and once it dries, many colors show after rust appears on the pyrite.

A pyroxenite is an ultramafic rock composed mainly by clinopyroxene, orthopyroxene and in minor amount, olivine (less than 40%). Depending of the modal mineralogy, the can be subclassified as orthopyroxenite (90% or more of opx), clinopyroxenite (90% or more than cpx), websterite (10% or less of olivine) and olivine-websterite (10-40% of olivine). Because the composition of these mineral phases is highly variable, pyroxenites have a broad range of compositions, however, they usually tend to have more SiO2 than peridotites.

I only know the minerals... They are quartz and pyrite and etc.
Quartz is harder than the streak plate, so instead of some of the quartz rubbing off and leaving a streak, when you rub quartz on the plate you're just scratching the plate itself.
