Amorphous silica materials in soils and sediments of the Ex-Lago de Texcoco, Mexico : an explanation for its subsidence

Abstract

Mexico city is built on the sediments of the former Texcoco lake, which are characterised by the presence of a siliceous deposit, up to 70 m in thickness, called jaboncillo. The jaboncillo is composed dominantly of amorphous silica and iron oxides and hydroxides, with minor amounts of phyllosilicates and detrital volcanic minerals. The mineralogy, the micromorphology and physical and chemical properties are discussed. The AA. aim to determine how far some of their properties change with loss of water due to the artificial drainage : increase risk of instability and subsidence of the sediments when used for construction
