The formation of placer gold deposits colls for a source with abundant auriferous materials, advantageous exogenetic agencies, opportune neotectonic movement and favourable deposional enviroment.Having been exposured on the surface for a long time and subjected to sustained weathering, the gold-bearing geological bodies broke down and disintegrated. The products were then transported and sorted by running water along valleys, and the gold was finally concentrated to form placer deposits. In valleys, gold was...

The formation of placer gold deposits colls for a source with abundant auriferous materials, advantageous exogenetic agencies, opportune neotectonic movement and favourable deposional enviroment.Having been exposured on the surface for a long time and subjected to sustained weathering, the gold-bearing geological bodies broke down and disintegrated. The products were then transported and sorted by running water along valleys, and the gold was finally concentrated to form placer deposits. In valleys, gold was transported in four forms: as single gold grains, by carriers, in"relays"and in solution. Their distances of transportation were different. In the process of transportation, these four forms coexisted but operated in different extent.The gold placers were formed in the early stage of the cycle of erosion of valleys under exogeuitic force in a surficial enviroment (normal temperature and pressure). The formation of the gold placers were directly affected by the current velocity and flow of the streams, character of neotectonic movement, geomorphological features of the valleys, nature of bed rocks of the valley floors, velocity of weatering and erosion and amount of auriferous materials.The placer gold orebodies all occur as zones or bands in sands and gravels and/or debris in the lower part of the valley fills (Figs: 4,5 and 6). The grade of the placer gold orebody varies slightly longitudinally (Fig. 10) but greatly laterally (Fig. 11 and 12). The gold particles are mainly flaky, tabular and granular, and intergrowths with gangues are often seen.When formed, the gold places suffered scouring and reworking due to downward and lateral erosion of the streams and flood currents, which were very favourable for gold enrichment at the bottom of the valleys.

人类历史上空前规模的金矿勘查热潮方兴未艾。近几年来,矿床地质学家对金矿地质研究取得了巨大的成果,但对金矿成矿作用的一些有关向题仍有较大的争议。本文概略地综述了西方国家在区域性的金矿成矿作用、某些世界著名金矿的重新研究、金矿实验研究、找金技术方法及金矿成因模式等5个方面的研究现状。

Most of separate gold deposits with hydrothermal-type have no direct relation with country rocks in origin. As the hosting space of the hydrothermal gold deposits, wailrocks are very important in respect to geology. In China, the predominant country rocks of gold deposits are the Proterozoic and Palaeozoic metamorphic rocks, but the young volcanic rocks and volcaniclastic rocks are put in the first place on abroad. Gold mineralization is closely related to the temperature and pressure of magmatic eruption and...

Most of separate gold deposits with hydrothermal-type have no direct relation with country rocks in origin. As the hosting space of the hydrothermal gold deposits, wailrocks are very important in respect to geology. In China, the predominant country rocks of gold deposits are the Proterozoic and Palaeozoic metamorphic rocks, but the young volcanic rocks and volcaniclastic rocks are put in the first place on abroad. Gold mineralization is closely related to the temperature and pressure of magmatic eruption and intrusion. The prospecting target of distinctive hy-drothemal gold deposits should be focused on the distributing areas of young volcanic rocks, volcanicastic rocks and sedimentary clastic rocks.

热液型独立的金矿床,绝大部分与围岩无直接成因联系。围岩作为热液型金矿赋存的空间条件,具有重要的地质意义。国内的金矿围岩以太古界和元古界的变质岩系占优势;国外则以年轻的火山岩、火山碎屑岩占首位。金矿的成矿作用与岩浆喷发和侵入活动的温压条件关系密切。我国热液型独立的金矿床找矿重点,应着重于年轻的火山岩、火山碎屑岩和沉积碎屑岩分布区。
