Relief patterns of radial shape frequently may indicate range of various
nature processes and phenomena which determine its genesis. Among them are
karst, volcanism, fluvial processes and impact events. Some results of landscape
research, mineralogical and spectral analyses of sedimentary rocks from ring
structures on the territory of Darwin Natural Reserve indicate a probable impact
interaction took place in the past which transformed the surface into a radial
depression. Some aspects and approaches to the use of indicate features of ringshaped structures genesis are discussed in the article.
