摘　　要：中国天然石英砂矿产地分布主要受新生代流域、海岸盆地、山间盆地及断陷盆地控制,成矿时间分布局限,形成时代主要集中于新近纪中新世至第四纪全新世,其中以全新世为主导,是中国天然石英砂矿的主要成矿时代,矿石质量较好。中国天然石英砂矿资源较丰富,地理分布较广,集中度高。矿床主要集中分布在广东、海南、广西、福建和山东的沿海地带。The distribution of natural quartz sand deposits in China is mainly controlled by Cenozoic basins,coastal basins,intermountain basins and fault basins.The distribution of mineralization time is limited,and the formation time is mainly concentrated in the Neogene Miocene to Quaternary Holocene,with Holocene as the dominant period,which is the main metallogenic era of natural quartz sand deposits in China,with good ore quality.China is rich in natural quartz sand resources,with wide geographical distribution and high concentration.The deposits are mainly distributed in the coastal areas of Guangdong,Hainan,Guangxi,Fujian and Shandong.
