        Some remnants of ancient geothermal activity, including fossil siliceous sinter, siliceous cap, silica cemented conglomerate and hydrothermal alteration, have been discovered and studied in the Shuikoushan ore area. The presence of these remnants shows that gold mineralization in the ore area had a close relation to geothermal activities and overprinted the contact metasomatism of Pb Zn. Therefore, the Kangjiawan gold deposit is a dissemination replacement deposit.

        Natural gas hydrate as a potential natural fuel resource, which occur worldwide in the polar regions, mostly associated with onshore and offshore permafrost, and in sediment of out continental and insular margins will provide human enormous energy in the coming 21 century. Three aspects of gas hydrates are important: their fossil fuel resource potential, their role as a submarine geologic hazard and their effects on global climate change. Gas hydrates have become the focus of intense international interest over the past few years because of their abundance and their potential role as a fuel, which could mitigate global climate change. Natural gas hydrate future face to challenges.

        人類在21 世紀后期面臨著油氣資源枯渴,尋求潔凈高效的新能源成為科學界追求的目標。為此,近三十年來,世界各國相繼投入了大量的資金和人力開展新能源研究。目前,人們在一種重要的新能源———氣水合物的基礎研究、地質調查、勘探開發等領域取得了較大的進展;但尚存在許多急待解決的重大理論問題,如天然氣水合物形成與分解的動力學過程和地質條件,氣水合物資源量計算辦法,經濟型天然氣水合物開采、開發模式,氣水合物對全球氣候的影響等。天然氣水合物作為化石燃料,具有巨大潛力;作為甲烷碳庫,是海底地質災害的誘因;作為溫室氣體,對全球氣候變化有著重要的影響作用。天然氣水合物研究未來面臨挑戰。

        Natural gas hydrates have become an exciting national and international research issue. Gas hydrates,also called gas clathrates, naturally occur in sollds comprised of water molecules forming a rigid lattice of cages with most of the cages, each containing a molecule of natural gas, mainly methane.Natural gas hydrates exists worldwide in the polar region, normally associated with onshore and off shore permafrost, and in sediment of outer continental and insular margins. The role that methane hydrates will play in contributing to the world's energy needs will depend on the availability, producibility, and cost of extracting methane from the hydrate phase. The generally accepted estimates of the total amount of methane that in gas hydrates is about twice the total methane of all fossil fuels (i. e. gas, oil, coal, etc. ) combined. However, if even a small portion of the suspected gas hydrate accumulation is producible, hydrates would have a significant impact as an energy resource. The total amount of methane in gas hydrates likely exceeds 1019g methane carbon. Three important research areas clearly emerge as common themes in all gas hydrate research plans: (1) hydrates as an energy resource, (2) hydrates as agent of global change, and (3) hydrates as a factor in sea floor stability and geohazards. Because natural gas hydrates represent a 1arge amount of methane within 2ooom of the earth's surface, they are considered to be an unconventional, unproven source of fossil fuel.Because gas hydrates are metastable, changes of pressure and temperature affect their stability. Destabillzed gas hydrates beneath the sea floor lead to geologic hazards such as submarine slumps and slides, examples of those are found worldwide. Destabilized gas hydrates may also affect climate through the release of methane, a "greenhouse" gas, which may enhance global warming and be an important factor in global climate change.I thought that in each of these aspects an imposing need arises for study that is both technically demanding and of publlc interest. Here we briefly review those three themes and their underlying scientific opportunitles,

        天然氣水合物廣泛存在于極地地區,通常與凍土帶的近海和深海以及陸架和島嶼邊緣密切相關。天然氣水合物具有三個方面的研究意義:作為化石燃料具有很大的資源潛力;作為臨界狀態物質,具有水下地質災害的潛在危害;作為有機碳庫,對全球氣候變化產生重要影響。氣體水合物賦存于地表淺層2000米深度。由于氣體水合物的不穩定性特征,溫度和壓力微小變化都將會造成水合物分解,發生地質災害,如海底滑塌、滑坡,此類災害在世界各地曾發生過多次,伴隨災害過程向大氣排放大量甲烷,對全球氣候變化產生一定影響。
