  We present BeppoSAX results of a spatially resolved spectral analysis of
A3571, a relaxed nearby cluster of galaxies. In the central 2' (130/h_50 kpc)
radius the metal abundance is 0.49 +- 0.08 solar and the absorption (1.13
+-0.28) x 10^21 atom/cm^2 whereas elsewhere within an 8'(520/h_50 kpc) radius
the abundance is 0.32 \+- 0.05 solar and the absorption consistent with the
galactic value of 4.4 x 10^20 atom/cm2. The significant central metal abundance
enhancement is consistent with the supernova enrichment scenario. The excess
absorption may be attributed to the cooling flow, whose mass flow rate is 80 +-
40 M_Sun/yr from our spectral fit. The BeppoSAX and ASCA radial temperature
profiles agree over the entire overlapping radial range r < 25' = 1.6/h_50 Mpc.
The combined BeppoSAX and ASCA temperature profile exhibits a constant value
out to a radius of 10' (650/h_50 kpc) and a significant decrease (T propto
r^-0.55, corresponding to gamma=1.28) at larger radii. These temperature data
are used to derive the total mass profile. The best fit NFW dark matter density
model results in a temperature profile that is not convectively stable, but the
model is acceptable within the uncertainties of the data. The temperature
profile is acceptably modeled with a ``core'' model for the dark matter
density, consisting of a core radius with a constant slope at larger radii.
With this model the total mass and formal 90% confidence errors within the
virial radius r_178 (2.5/h_50 Mpc) are 9.1+3.6-1.5 x 10^14 h_50^-1 M_Sun, by a
factor of 1.4 smaller than the isothermal value. The gas mass fraction
increases with radius, reaching f_gas(r_178) = 0.26+0.05-0.10 x h_50^-3/2.
Assuming that the measured gas mass fraction is the lower limit to the
primordial baryonic fraction gives Omega_m < 0.4 at 90% confidence.
