| 中文摘要:本文对我国锶矿资源的类型、特征、时空分布和成矿谱系进行了分析和总结, 初步总结了我国锶矿床的成矿规律。介绍了我国锶矿产资源的特点, 对锶矿床预测类型进行了分类, 并对锶矿床的形成年代和空间分布进行了统计分析。将中国锶矿床划分为五大预测类型: 沉积型、层控型、热液型、岩浆型和表生型。初步总结了各类锶矿床的时空分布特征。将中国锶矿床成矿期划分为新元古代、早古生代、晚古生代、中生代和新生代五个时期, 并将其划分为11个锶成矿带。本文确定了30个与锶矿床有关的成矿系列, 并建立了锶矿成矿谱系。通过综合研究发现, 北方地区以新生代柴达木地区层控型锶矿为主, 南方地区集中在晚古生代、中生代、新生代四川盆地和长江中下游的层控型和热液型锶矿。柴达木、长江中下游、四川盆地可作为锶矿找矿远景区。 |

| Abstract:This article examines the characteristics, types, and spatiotemporal distribution of strontium resources in China and summarizes the ore-forming regularities of strontium deposits. It introduces the resource characteristics of strontium deposits in China, divides prediction types, and collates mineralization ages and spatial locations of strontium deposits. Strontium deposits in China can be classified into five types: strata-controlled, sedi-mentary, hydrothermal, epigenetic, and magmatic types. The spatiotemporal distribution characteristics of each type of strontium deposit are preliminarily delineated. According to statistics, the mineralization periods of strontium deposits in China can be divided into the Neoproterozoic, Early Paleozoic, Late Paleozoic, Mesozoic, and Cenozoic eras. Eleven strontium mineralization zones are divided, 30 mineralization series related to strontium are identified, and the mineralization lineage of strontium deposits in China is established. Based on comprehensive research, strontium deposits in northern China are mainly characterized as the strata-controlled type in the Cenozoic Qaidam. Strontium deposits in southern China are mainly characterized as strata-controlled type and hy-drothermal type in the Late Paleozoic, Mesozoic, and Cenozoic Sichuan Basin and the middle and lower reaches of the Yangtze River. The Qaidam Basin, the middle and lower reaches of the Yangtze River, and the Sichuan Basin can serve as exploration prospects for strontium. |
