De- nudational Processes during tho Last 20,000 Years In the Basin of Mo- xico, Mexico

Year, pages: 1989, 353 - 367

The Basin of Mexico is one of a serie of continuous tectonic basins in central Mexico territory. Formed by the disruptions of the Pliocene and Pleistocene volcanic activity. The broad, pyroclastic-alluvial and lacustrine sediments filled the basin which is surrounded by volcanic (andesitic) highlands, which attain an elevation over 4000 m.a.s.l. Its floor lies at an altitude of 2240 m.a.s.l. Sediment in and around the margins of the basin, provides a record of alluvial conditions extending over Holocene period. Examinations of these deposits provides Information on the erosional procedure in terms of their sediments source. Key elements of this study includes: Tectonic activity and climate changes during the upper Pleistocene and Holocene periods and its effects on erosional and depositional processes. Finally deducing the soil formation periods by correlation with terrace sequences.
