China has widely distributed silver deposits,and is rich in silver resources.Although silver deposits are mainly associated with Pb-Zn deposits,a number of independent silver deposits have also been discovered in recent years.Silver deposits include different types,such as submarine volcanism and continental volcanism related type,intrusion related type,and sedimentary related type.This study summarized the metallogenic regularity of China’s silver deposits systematically based mainly on the data from 490 silver deposits.It is shown that submarine volcanic sedimentary type,continental volcanic or sub-volcanic type,skarn type,hydrothermal type(including vein type and stratabound type),sedimentary metamorphic type,sedimentary type and regolith type should be regarded as the most important prediction types of silver deposit.A total of 32 silver mineralization belts and 111 silver concentration areas have been delineated.The map of “Spatial distribution of silver mineralization belts in China” and other series of maps finished in this study may provide a theoretical basis for the evaluation and prognosis of silver resources potential in China.

根是植物由海洋登上陆地后,逐渐演化出的杰出的营养器官之一。有了根,植物才得以在地球陆地复杂多变的气候条件下“驻足”吃喝,以静为动,生生不息……避免了像许多动物那样,以全身运动的能耗去换取生活必需的食物。因此,植物中的长寿者可以活上千年甚至近万年,而体形巨大者的地上部分可以长到上百米高,重量达2000多吨。同时,植物又通过根的种种变态本领,以变应变,在森林、草原、山岳、湿地和沙漠等陆地生态环境中为自
