Abstract

During the years of 2013-2014 the Institute of Geology and Environment carried out one research for establshing the geological - mineral map at the scale of 1:50.000 of the whole enlarged Hà Nội City. The map was established on the basic of old geological maps, the results of additional field trips on the distribution of some geological units, the locations of some mineral deposits and the results of remote sensing data interpretation. The map is on VN 2000 coordinate system with topographic base, contains many information layers and covers the whole territory of new Hà Nội (old Hà Nội and the new added areas). On this map, the main contents are interpreted, such as: the distribution of geological units (23 stratigraphic units and one intrusive magmatic complex); geological bounaries; photolineaments; ring structures; mineral deposits; some types of geoharzads and the other additional informations.
