| 中文摘要:粤西是我国华南的主要金、银矿床集中医，医内金矿床与银（金）多金属矿床具有相间排列的分布规律，即从南到北分为以下5个矿带：廉江地区银（金）多金属矿带、高州-信宜金矿带、罗宁-云浮银（金）多金属矿带、德庆-清远金矿带、连山地区银（金）多金属矿带。本文从区域地层、岩浆岩及成矿作用等方面对粤西金、银矿床区域分布规律进行了探讨，认为影响金、银矿床分布的主要因素是不同区域地层、岩浆岩Au、Ag含量的差异及金矿床与银（金）多金属矿床成矿作用的差异。 |

| Abstract:Western Guangdong is an area where gold and silver deposits occur concentratedly. In this area, gold deposits and silver (gold) polymetallic deposits are arranged alternately: from south to north, there exist five metallogenic belts: silver (gold) polymetallic ore belt of Jianjiang area, Gaozhou-Xinyi gold ore belt, Luoding-Yunfu silver (gold) polymetallic ore belt, Deqing- Qingyuan gold ore belt, arid silver (gold) polymctallic ore belt of Lianshan area. In the light of regional strata, magmatic rocks and ore-forming processes, the present paper has made a relatively thorough discussion on the distribution regularity of gold and silver deposits. It is held that the main factors affecting the distribution of gold and silver deposits are discrepancies in gold and silver contents of different strata and magmatic rocks as well as differences in metallogenesis between gold deposits and silver (gold) polymetallic deposits. |
