摘　　要：硅石矿为宁夏的优势矿种,基本查明硅石矿产地的有34处。硅石矿类型有受变质型、变成型、机械沉积型、砂矿型。长城纪、中新世和渐新世为主要成矿期。根据对现有矿床(点)的成矿地质规律的研究,在宁夏成矿区带的基础上,明确了与硅石资源相关的7个Ⅳ级成矿亚区(带)和2个Ⅴ级矿集区,总结了硅石矿时空分布规律。厘定出5个与硅石相关的矿床成矿系列,总结了硅石矿成矿谱系。提升了硅石矿成矿规律研究的程度,为宁夏硅石资源的潜力评价预测工作提供了理论依据。The silica ore is the dominant mineral species in Ningxia,there are 34 basic identified silica ore areas.The types of silica ore include metamorphic type,metamorphic type,mechanical deposit type and placer type.The Changcheng period,Miocene and Oligocene are the main metallogenic periods.Based on the study of metallogenic geological rules of existing deposits(points),on the basis of metallogenic belt in Ningxia,sevenⅣ-grade metallogenic subregions(belts)and twoⅤ-grade ore concentration areas related to silica resources are identified,the spatio-temporal distribution rules of silica ore are summarized.Five metallogenic series related to silica deposit were determined and the metallogenic pedigree of silica ore was summarized.The research on metallogenic regularity of silica ore is improved,which provides a theoretical basis for the potential evaluation and prediction of silica resources in Ningxia.
