中文摘要:

      云南兰坪—思茅盆地是我国重要的成钾盆地。综合前人的研究成果,简要介绍了该地区的地质概况。对兰坪—思茅盆地钾盐矿床的物质来源进行了阐述和讨论,认为该盆地钾盐矿床的物质来源以残存古海水为主,并有陆源水体的补给。盆地内的富钾火山凝灰岩、古盐和风化盐也可能为该盆地钾盐矿床提供物源,至于深部地下卤水是否提供物源还需更深入的研究论证。兰坪—思茅盆地钾盐矿床成矿物源具有多源性。

英文摘要:

      Lanping-simao basin that contains potash deposit is an important basin in China.Based on previous research,the general geology of Lanping-Simao basin and the material sources of potash deposit are discussed here.The results show that the main material sources of the potash deposit in this basin are archaic seawater and terrestrial water.Potassium-rich volcanic tuff in this basin,ancient salt and weathering salt may also be the material source.For deep underground brine,further studies are needed.The materia...
