The non-uniform temperature and abundance distribution in the central region of A3571 is investigated. Our previous analysis of ASCA data suggested that the cluster experiences a relatively large scale group infall. By the advantage of XMM-Newton's high angular resolution, we are able to investigate dynamical structures down to the 100 kpc scale. We found several cool and hot patchy regions within the angular extend of 6′ from the center. There is a significant temperature difference among patchy clumps of about 2 keV in the ambient ICM, which has an average temperature of 7.1 keV. Referring to the abundance map of the same region, we found a variation of metalicity ranging from 0.28 to 0.65 times solar, while the average value is 0.33 times solar. Using the temperature, metalicity and galaxy distribution, as well as the pressure and entropy maps, we discuss the dynamical structure of the ICM.
