Title: Matallo Gelolgical Conditions of Silver Deposits in the Northwestern Part of Hebei Province
Abstract: The northwestern part of Hebei province is a trigonal terrane conjoined by Siberian plate, North china plate and pacific ocean plate, in which regional structure is complicated, magma acts frequentely, and so it is a favourable terrane for ore forming, Silver ore resources are abundant in the area Silver ore deposits can be divided into three types,they are magmatic hydrothermal,volcano subvolcanic hydrothermal and strata bound The ore deposits were densely distributed in the tectono magmatic rock belt of circum pacific ocean within the eastern area of east longitude 115°. The most favourable metallo geological conditions for ore forming were the litho stratagraphic beds or rock bodies contained more ore forming materials,the structural environments provided the space for ore originating and ore hostig,and the frequent magmatic activities suplied the heat source and ore materials Yanshanion is the major ore forming period of silver deposits in this area
