摘要:

巨型矿床是矿产勘查的理想目标,其形成与定位是当前地球科学领域重大国际研究前沿。矿体空间分布规律对认识巨型矿床形成与定位和预测找矿至关重要。胶东作为世界第三大金矿集区,产出焦家、三山岛、玲珑3处超千吨巨型金矿床,成为研究巨型金矿床的热点地区。台上-水旺庄金矿床位于胶东金矿集区招平断裂带北段,近年来在500~2 500 m深度取得重大找矿突破,累计探明金资源量700余吨,达到巨型规模,是研究巨型金矿床矿体空间分布规律和找矿模型的理想对象。本文在系统梳理浅部和深部勘查成果的基础上,剖析了矿体的空间分布规律,提出了分段富集规律,构建了深部找矿模型,并进行了深部矿体定位预测、定量预测和靶区验证。研究发现:(1) 主矿体的空间分布受控于招平断裂带,呈较规则的脉状赋存于主裂面下盘的黄铁绢英岩化蚀变带内,沿走向和倾向具有膨胀夹缩和尖灭再现的特点;(2)矿化强度与控矿断裂倾角变化密切相关,控矿断裂倾角陡-缓转折部位和倾角相对较缓(倾角为10°~35°)部位易富集成矿;(3)主矿体总体向NEE侧伏,沿侧伏方向具有分段富集且富矿段之间具近似等间距的分布规律;(4)Ⅰ号矿体53~149号勘探线-2 800~-1 200 m标高范围为深部有利赋矿位置;(5)体含矿率法预测-5 000~-2 000 m潜在金资源量为642~723 t;(6)靶区验证结果证明本文建立的预测方法科学有效,为矿区及胶东同类型金矿的深部找矿提供了有力指导。

Abstract:

Giant deposits are prime targets in mineral exploration, and understanding their formation and localization is a major research frontier in earth sciences. The spatial distribution pattern of ore bodies is crucial for this understanding and for prospecting. The Jiaodong Peninsula, the world’s third-largest gold province, is a hotspot for giant gold deposit studies, hosting multi-hundred-ton deposits like Jiaojia, Sanshandao, and Linglong. The Taishang-Shuiwangzhuang deposit, located in the northern Zhaoping Fault belt, is a recent successful exploration case at depths of 500 to 2 500 m, with proven resources exceeding 700 tons, making it an ideal site for studying ore body distribution and prospecting models. Based on a systematic review of shallow and deep exploration results, this study analyzes the spatial distribution pattern of ore bodies, proposes sectional enrichment characteristics, constructs a deep exploration model, and performs predictive targeting and verification. The results show that: (1) The distribution of the main orebodies is strictly controlled by the Zhaoping Fault. They are hosted in pyrite-sericite-quartz altered rocks beneath the main fault plane and exhibit pinch-and-swell structure and recurrence along strike and dip. (2) Mineralization intensity correlates with variations in the fault’s dip angle. Enrichment zones are primarily found where the fault transitions from steep to gentle dips and in the gently dipping segments with angles between 10° and 35°. (3) The main orebodies generally pitch towards NEE, showing a sectional enrichment pattern along pitch with approximately equally spaced gold-enriched zones. (4) The elevation range of -2 800 to -1 200 m between exploration lines 53 and 149 of No.Ⅰ orebody is highly prospective for deep ore bodies. (5) The potential gold resources from -50 00 to -2 000 m elevation are predicted to be 642-723 tons using the volume -grade method. (6) Verification in the target area confirmed the effectiveness of this predictive methodology, providing robust guidance for deep prospecting.
