广东濒临南海,海岸线2 000余km,蜿蜒的海岸构成无数的海湾,入海江河发育,大陆上的各种花岗岩、混合岩、砂岩等岩石经受长期的风化剥蚀、搬运、淘洗分选,为石英砂矿的富积成矿提供了良好的条件。以往常把石英砂统划为滨海沉积的海砂,我们根据野外观察研究,按照石英砂矿产出的部 Guangdong is on the verge of the South China Sea, with a coastline of more than 2,000 km. The winding coasts form countless gulfs. The rivers entering the sea are developed. Various types of granites, mixed rocks and sandstones on the mainland are subject to long-term weathering and erosion, handling, Quartz sand enrichment mineralization provides good conditions. Quartz sand has always been planned for the coastal sediment of the sea sand, according to our field observation study, according to the Department of quartz sand output
