| 英文摘要 | The Dachang superlarge Sn-polymetal deposit in Guangxi, China, is one of the largest tin deposit all over the world. However, this deposit has long been in debate as to its origin. One of the opinions is that the Dachang deposit was formed by replacement of hydrothermal solution originating from Yanshanian granites, and the other is that this deposit was formed by submarine exhalation in the Devonian. This paper presents some new isotopic geochronology data obtained with the Ar-40-Ar-39 method for quartz and sanidine from massive ore in the No. 91 and No. 100 orebodies. Analytic results show that the No. 91 orebody was formed at 94.52 +/- 0.33 Ma (the plateau age obtained with the Ar-40-Ar-39 method for quartz) or 91.4 +/- 2.9 Ma (the plateau age obtained with the Ar-40-Ar-39 method for feldspar), while the No. 100 orebody was formed at 94.56 +/- 0.45 Ma (the plateau age obtained with the Ar-40-Ar-39 method for quartz), suggesting that both the No. 91 and the No. 100 orebodies were formed at the Late Yanshanian instead of the Devonian. The No. 100 orebody might be formed by filling of ore materials into caves in Devonian reef limestone. Because the ore-bearing solution released its pressure and lowered its temperature suddenly in a cave environment, ore minerals were formed concentratedly while water and other materials such as CO2 evaporated quickly, resulting less alteration of host rocks. |
