Recovering a Gaussian distribution from its minimum

Let $X=(X_1,X_2, X_3)$ be a Gaussian random vector such that $X\sim \mathcal{N} (0,Σ)$. We consider the problem of determining the matrix $Σ$, up to permutation, based on the knowledge of the distribution of $X_{\mathrm{min}}:=\min(X_1, X_2, X_3)$. Particularly, we establish a connection between this identification problem and a geometric identification problem in the context of the theory of the circular radon transform.
