In the Guerrero-Morelos platform (Guerrero State, Mexico) the adakitic rocks of Early Tertiary age contain abundant hornblende-rich tonalite xenoliths.Zircon crystals have been concentrated from Inter- and transdisciplinary scenario construction to explore future land-use options in southern Amazonia both adakites and xenoliths, and dated using in-situ U-Pb ion microprobe analyses.These analyses indicate the presence of inherited Grenvillian and early Triassic/late Permian crust ages, as well as a Paleocene age related with the adakite rock intrusion.This range of inherited ages is reported for the first time in the Guerrero-Morelos platform, suggesting that a continous Grenvillian crust exists between the Oaxacan complex,to the East, Comparison of effects of spatial anticrime in open communities in China and the Guerrero-Morelos platform.
