苏北新沂—宿迂—泗洪沿郯庐断裂带地段经地质工作,相继发现和探明了新沂城岗石英白砂矿,宿迂白马涧、嶂山桥玻璃砂矿,泗洪梅花、重岗瓷石砂矿和其它一系列砂点及建筑黄砂矿。从目前掌握的资料来看,它们在实际上是一个矿田内一种类型的矿物组合,只是由于当时工业要求和勘探目的不同,对矿砂的粒度要求不一致,造成同一种原料而称法不同的矿床。为了更好地综合评价该种资源,有必要归类统一,以便研究和工业利用。
Northern Jiangsu Xinyi - Suqian - Sihong along the Tanlu fault zone by the geological work, have been discovered and proven Xinyi Chenggang quartz white sand, Suqian white horse stream, Dangshan bridge glass sand, Sihong plum, Dangang porcelain stone sand mine and a series of other sand spots and building yellow sand ore. Judging from the information available at the moment, they are actually a type of mineral assemblage in a minefield, only because of the different industrial requirements and exploration objectives at that time, which require inconsistencies in the particle size of the ore and result in deposits of the same type, . In order to better integrate such resources, it is necessary to classify them for research and industrial use.
