However, this interpretation has been challenged by advocates of recycling and preservation models; they propose that the peaks record periods of enhanced preservation of crust during the assembly of supercontinents (Condie and Aster, 2009, 2010; Hawkesworth et al., 2010; Voice et al., 2011). In summary, it is a hot research topic which is still very much debated. If someone has the answer here at Stack Exchange, he/she should apply for the Penrose medal! :)
