摘要

 
    

The data processing and field investigation indicate that there are 42 iron deposits (spots) which have been found in ace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />ace w:st="on">Laosace>. Some of them are very important, such as Vangviang iron deposit in Vientiane province, Phou Nhouan iron deposit in aceName w:st="on">XiangkhouangaceName> aceType w:st="on">ProvinceaceType>, Pha Lek iron deposit in ace w:st="on">Vientianeace> Province, Ban Nonglao iron deposit in Khammouan Province and so on. These important deposits are occurred in the form of stratiform-like and vein-shaped bodies with high ore quality, and belong to contact metasomatic deposits and hydrothermal deposits. According to the conditions of strata, magmatic rocks, tectonics and the distribution of deposits (spots), 3 metallogenic prognosis districts can be divided in ace w:st="on">Laosace>, namely, Louangphabang, Muang Pek and Xam-Nua.
