中国硼矿主要矿集区及其资源潜力探讨

DISCUSSION ON CHINA BORON-CONCENTRATING AREA AND THE RESOURCE POTENTIAL

在分析中国硼矿床成因类型的基础上,将中国硼矿床划分沉积变质、现代盐湖沉积、矽卡岩和地下卤水4个矿床类型8个矿床式,最为重要的矿床类型为沉积变质型硼矿和现代盐湖型沉积硼矿床。在硼矿成矿区带划分方案的基础上,综合成矿规律、地质构造背景等因素划分出辽-吉沉积变质型、川-鄂地下卤水型、湘-桂矽卡岩型、西藏现代盐湖型和青海柴达木现代盐湖型5个硼矿矿集区。其中辽-吉老矿区深部和外围、川鄂区的地下卤水及盐湖硼矿的综合利用等方向尚有较大潜力。

The paper divides China boron deposits into four types and eight styles according to the analysis on their cause of formation, those are sedimentary metamorphic type, modem saline sedimentary type, skam and underground brine type, the most important ones of which are sedimentary metamorphic and modern saline types. On the basis of boron-forming zone classification plan, as well as the forming regularity and geological structure background, we also classify five sedimentary metamorphic, modem saline sedimentary, skam and underground brine boron-concentrating areas, including Liaoning-Jilin sedimentary metamorphic type, Sichuan-Hubei underground brine type, Hunan-Guangxi skam type, Tibet modern saline and Qinghai Chaidamu modem saline type. The underground brine and saline boron in depth and periphery part of Liaoning-Jilin, Sichuan-Hubei district, have more potential for comprehensive utilization.
