福建漳浦山门石英砂矿地质特征及成因探讨

Geologic Characteristic and Genesis of the Sanmen Quartz Sand Deposit in Zhangpu County,Fujian Province

山门石英砂矿主要贮存于长乐组海积层中,矿体近水平层状产出,主要受物质来源、地貌和水动力与新构造运动等条件控制,矿床成因类型属滨海堆积。区内石英砂资源量大且质优,成矿地质条件好。

The Sanmen quartz sand deposit exists mostly in the marine deposition bed of Holocene Changle Formation. The ore bodies are distributed as a near horizontal stratiform occurrence and are controlled by the geological conditions such as substance sources, landform, hydrodynamic forces and neoteetonic movements. The genetic type of the ore deposit is the type of an offshore accumulation. The ore-forming geological conditions are better for the deposit and the quartz sand in the surveyed area is larger in resources and excellent in quality.
