锂是重要战略性矿产，是中国实现“双碳”目标的新能源产业关键资源，目前中国锂资源对外依存度较高，亟需解决锂矿资源储备，提高锂资源自给率。江西花岗岩云母型锂矿具有规模大、品位低、埋藏浅、易开采的特点，是重要的锂矿资源来源，该类型锂矿的快速找矿突破与开发利用，将有效降低中国锂资源对外依存度，对中国新能源产业的可持续、高质量发展具有重要的战略和政治意义。文章以江西宜春地区九岭南缘甘坊矿集区花岗岩云母型锂矿为研究对象，通过对花岗岩云母型锂矿成矿地质背景、成岩成矿作用及时空分布特征进行研究，总结成矿规律，构建了“高分异复式花岗岩+岩浆热液流体交代+化探和重砂异常+地质工程验证”花岗岩云母型锂矿综合找矿模式，为花岗岩型锂矿找矿靶区快速圈定，实现锂矿找矿快速突破提供理论依据和勘查关键方法技术。

Lithium, as a crucial strategic mineral, serves as the core resource for China’s new energy industry in realizing the“ Dual Carbon” goals. Currently, China exhibits a high external dependence on lithium resources, making it imperative to expand lithium reserves and enhance the self-sufficiency rate. The granite-mica type lithium deposits in Jiangxi Province are characterized by large scale, low grade, shallow burial depth, and easy exploitation, which have become an important source of lithium resources in China. The rapid prospecting breakthrough and rational development and utilization of this type of lithium deposit will not only effectively reduce China’s external dependence on lithium resources but also exert profound strategic and political significance for the sustainable and high-quality development of China’s new energy industry. In this work, the granite-mica type lithium deposits in the Ganfang ore concentration area, situated on the southern margin of the Jiuling Mountains within the Yichun region of Jiangxi Province, were selected as the research focus. Through systematic investigations into the metallogenic geological setting, magmatic-rock forming and mineralization processes, as well as the temporal and spatial distribution characteristics of the granite-mica type lithium deposits, the metallogenic regularity was comprehensively summarized, and a prospecting model specific to this type of lithium deposit was constructed. This research is intended to provide theoretical foundation and key exploration methodologies for the rapid delineation of prospecting targets of granite-type lithium deposits, thereby facilitating the achievement of major breakthroughs in lithium prospecting.
