Abstract
本申请实施例公开了基于沉积耦合控制下的龙门山锰矿成矿数据预测方法及系统，为地质勘探与数字仿真交叉技术领域；本申请实施例可以获取目标研究区采样点的三维构造变形强度张量及多维成因特征，解算构造演化历史并构建逆变换矩阵。利用该矩阵对当前地质体进行逆向复原，重建去构造化的成矿期古地理模型与古水动力场格架。将成因特征量化为边界条件，在复原格架内对锰元素沉积富集过程进行三维耦合数值模拟，得到初始沉积相模型。结合模型分布特征与有利地质标志计算成矿概率分布。利用互逆的正向变换矩阵将高概率区域映射回当前大地坐标系，生成锰矿成矿预测图。本申请实施例提升复杂造山带深部及隐伏锰矿靶区预测的准确性、科学性与可靠性。
