tyle="MARGIN: 0cm 0cm 0pt" class=MsoNormal>The data processing and field investigation indicate that there are 42 iron deposits (spots) which have been found in ml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />t1:country-region w:st="on">t1:place w:st="on">Laost1:place>t1:country-region>. Some of them are very important, such as Vangviang iron deposit in t1:City w:st="on">Vientianet1:City> province, Phou Nhouan iron deposit in t1:PlaceName w:st="on">Xiangkhouangt1:PlaceName> t1:PlaceType w:st="on">Provincet1:PlaceType>, Pha Lek iron deposit in t1:City w:st="on">t1:place w:st="on">Vientianet1:place>t1:City> 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 t1:country-region w:st="on">t1:place w:st="on">Laost1:place>t1:country-region>, namely, Louangphabang, Muang Pek and Xam-Nua.
