The focus of this chapter is a recently discovered archaeological site, Arroyo Piedras Azules, located on the northern Pacific coast of Jalisco, Mexico. Excavated materials provide considerable information about the colonization of this area by Aztatlán groups in the Early Postclassic period, as well as the nature of the expansion of the Aztatlán phenomenon in West Mexico. Based on the data thus far obtained from the site, the authors offer five significant conclusions regarding the development and the spread of the Aztatlán archaeological culture in West Mexico, concerning the timing of development, subsistence strategies of Pacific coastal groups, the nature of Aztatlán expansion, specialized production, and links between the Arroyo Piedras Azules site to the Mixteca-Puebla area.

AbstractAuthigenic clay minerals in the German Rotliegend formed mainly at burial depths >1.5 km. Illite is the dominant cement, although kaolinite, dickite and early radial chlorite are abundant locally. Illites contain more AI and late chlorites more AI and Fe in sequences showing extensive grain dissolution. This relationship between clay chemistry and grain dissolution suggests that clay cementation is linked to grain dissolution. Sequences at relatively shallow burial depths (<3-5 km) contain less clay cement. In the more deeply buried sections, increased illite and kandite cementation, together with extensive grain dissolution, is evident where the Rotliegend is juxtaposed against Carboniferous Coal Measures. Faults also acted as important conduits for acidic fluids. Illite and kandite growth occurred at similar depths and from waters of similar isotopic composition (618O = 1-6‰ SMOW) throughout most of the Southern Permian Basin. However, the timing of illite growth varied between areas and corresponded to periods to tectonic activity.
