我国找矿有重大发现！

Core Viewpoint - Jiangsu Province has discovered a large strontium ore deposit in the Lishui Basin, with inferred resource amounts reaching 545.55 thousand tons and an average grade of 48.65% [3][5]. Group 1: Discovery and Significance - The newly discovered strontium ore deposit is located in the northeastern part of the Lishui volcanic basin, surrounding the Aijing Mountain large strontium deposit [3]. - Strontium, as an important rare metal, is widely used in special ceramic materials and magnetic alloy manufacturing, playing a crucial role in national industrial development and technological advancement [3]. Group 2: Exploration Efforts - The geological survey team has spent four years on strontium exploration in the Lishui area, addressing challenges such as extensive Quaternary cover and significant human activity [5]. - The project team proposed a new understanding of the second mineralization space in the basement fault of the Kaitai-Baimashan area, based on the structural evolution history of the Lishui Basin [5]. Group 3: Findings and Models - The project team discovered five concealed strontium ore bodies in the Mashantou area and submitted one large strontium ore deposit, providing direction for future exploration in the Lishui Basin [5]. - A comprehensive study established a mineralization model and exploration model for strontium in the Lishui Basin, offering an effective technical methodology for future exploration [5]. Group 4: Additional Discoveries - The northeastern part of the Lishui Basin is a significant area for strontium resources, with four large and medium-sized strontium deposits already identified [6]. - The project team also discovered multiple concealed copper, lead-zinc, and iron-sulfur ore bodies, proposing a new multi-metal comprehensive exploration approach for strontium, copper, and lead-zinc [6].
