Abstract.For integers $1 le p < n$, we consider $mathbb{R}^{n imes n}$-valued Radon measures $mu = (mu_{alphaeta})$ on an open set $Omega subset mathbb{R}^n$which satisfy $$int_Omega left({
m div} phi dmu_{alphaalpha} - p , frac{partialphi^alpha}{partial x^eta} dmu_{alphaeta}
ight) = 0$$ for all $phi in C_0^1(Omega,mathbb{R}^n)$. We show that under certain conditions, $mu$]*> has an (n - p)-dimensional density everywhere, and the set of points of positive density is countably (n - p)-rectifiable. This simplifies the proofs of several rectifiability theorems involving varifolds with vanishing first variations, p-harmonic maps, or Yang-Mills connections.
