Quartal or Double Fourth Chords, are chords made up of the Root, fourth and flatted seventh:
Q3=[1,4,7b]
So, my question for you guys is. Is this chord Major or minor?
And do you know of any chord progression that includes a Q3 chord?
Notice in the generic formula that the seventh is flatted, making it a minor seventh. But both major and minor triads can have a flatted seventh added.
7=[1,3,5,7b]
-7=[1.3b,5,7b]
.
Q3 Chords.

It's neither major nor minor, it's quartal.
Hmm...Lemme see, you COULD, in Aminor use a G quartal chord: G-C-F
You could use an A quartal as well, or an E quartal chord.
But since the chords are based around an entirely perfect interval (the fourth) they can be neither major nor minor. Kind of the same way power chords are neither major nor minor.

The way I see it. It`s a minor chord. Let me show you why.
A Quartal chord is based in Quartal Harmony instead of Tertian Harmony. That means using intervals of fourth to build chords.
Take a "C Major Scale"
C D E F G A B C D E F
1 2 3 4 5 6 7 8 9 10 11
Now start on the 2nd(D) and add intervals of fourth above it. You get:
DQ=[D,G,C,F]
That "F" at the end defines the chord as a minor.
So, in a common Jazz Progression( ii7-V7-I )
in the key of "C"; that`ll be........( Dm7-G7-C )
Now take a look at the notes of the (Dm7 chord) and the notes in the (DQ chord):
Dm7=[D,F,A,C]
DQ= [D,G,C,F]
You can sustitut the Dm7 and play the jazz progression as fallows:
DQ-G7-C.

Also, if you have a progression that includes a G7sus chord, you can throw a DQ chord.
G7sus=[G,C,D,F]
DQ=[D,G,C,F]
By the way when I say "DQ" I`m not talking about Dairy Queen.
And if you wanna writte a "B flat quartal" would you say BbQ.
I think I`m hungry.
G7sus=[G,C,D,F]

Yeah, but a minor seventh doesn't make a chord major or minor as far as the root third and fifth are concerned. You could have a Major-minor seventh chord...but hmm... Yeah, I guess I'd call it a Quartal-minor seventh chord...eeeenteresting.
