Una aproximación al Periodo Formativo en el valle del Chillón

Abstract

An Approach to the Formative Period in the Chillón Valley

The author describes 29 Formative sites in the Chillon Valley subdivided into monumental architecture (U-shaped buildings, pyramid with circular sunken courts and simple pyramids) and 17 domestic sites. A typology of the recollected ceramics is given as well as comparisons with other sites and chronological proposals. U-shaped complexes are concentrated in the lower valley but located up to km 59. Huacoy is the largest one of them, communicated with Ancon and related with 8000 has of arable land. Chocas is probably a minor copy of Huacoy and part of the system, while Pucara integrates the middle valley.
