The Duobuza porphyry copper-gold deposit(proven Cu resources of 2.7 m.,0.94%Cu and 13t gold, 0.21 gt Au) is located at the northern m.rgin of the Bangong-Nujiang suture zone separating the Qiangtang and Lhasa *** m.jor ore-bearing porphyry consists of *** alteration zone extends from.silicification and potassic alteration close to the porphyry stock to m.derate argillic alteration and propylitization further *** alteration is not well ***-quartz veins only occur ***-tem.erature, high-salinity fluid inclusions were observed in quartz phenocrysts and various quartz *** fluid inclusions are characterized by sylvite dissolution between 180 and 360℃and halite dissolution between 240 and 540℃, followed by hom.genization through vapor disappearance between 620 and 960℃.Daughter m.nerals were identified by SEm.as chalcopyrite,halite,sylvite,rutile,K-feldspar,and *** indicate that the fluid is rich in ore-form.ng elem.nts and of high oxidation *** fluid belongs to a com.lex hydrotherm.l system.containing HO-NaCI-KCI±FeCI±CaCI±*** decreasing hom.genization tem.erature, the fluid salinity tends to increase from.34 to 82 wt%NaCI equiv.,possibly suggesting a pressure or Cl/HO increases in the original *** coexisting vapor-rich fluid inclusions with sim.lar hom.genization tem.eratures were found,so the brines are interpreted to have form.d by direct exsolution from.m.gm. rather than trough boiling off of a low-salinity *** m.nim.m.pressure of 160 m.a im.ly approxim.tely 7-km.*** indicates that the deposit represents an orthom.gm.tic end m.m.er of the porphyry copper deposit *** key factors are proposed for the fluid evolution responsible for the large size of the gold-rich porphyry copper deposit of Duobuza:(i) ore-form.ng fluids separated early from.the m.gm.,and(ii) the hydrotherm.l fluid system.was of m.gm.tic origin and highly oxidized.

金厂峪金矿床是冀东最大的金矿床 ,具有早期复脉型和晚期石英大脉型两种矿石类型。矿区产有多期钠长岩脉 ,且与含金矿脉有密切的时间和空间关系。青山口花岗岩体位于矿区西约 2～ 3km.有研究者认为金矿床成因上与花岗岩体有关。应用先进的 SHRIm.测年技术 ,测得肉红色钠长岩脉的锆石 w (2 0 7Pb) / w (2 0 6Pb)年龄为 (185 8± 8) m.,青山口花岗岩体锆石 w(2 0 6Pb) / w(2 3 8U )年龄为 (199± 2 ) m.。金厂峪金矿床的的复脉型矿化早于肉红色钠长岩脉 ,故其矿化的时代应在晚元古代。青山口岩体的年龄和区域上与辉钼矿化有关的花岗岩年龄一致 ,均为燕山早期。推测金厂峪金矿床晚期石英大脉型矿化中的辉钼矿化可能与青山口花岗岩体有关。
