摘要
本文详细剖析了胶东地区招掖金矿带的成矿构造体系——新华夏系断裂构造的结构特点、力学性质、演化特征、形成机理及其对金矿带的控制作用,突出了构造活动与成矿时序的研究。同时,还采用当代新崛起的灰色系统理论和方法解决本征小样本地质构造离散数据建模的问题,揭示了控矿构造内部和外部标志,在其性质、程度、范围、趋势等方面的变化和关联特征,以及与矿化标志、矿体相对优劣程度,在多维时空上的传递演化规律,为隐伏矿床(体)和远景区的研究及预测提出了新的认识与途径。
The paper analyses in details the structural features, mechanical properties, evolutionary characteristics and formation mechanism of the metallogenic structural system——Neocathaysian fracture structre——in the Zhaoyuan-Yexian gold belt of Jiaodong peninsula and its control on the gold ore belt. The emphasis is put on the study of structural activity and mineralization time sequence. By applying the theories and methods of the gray-system the authors have solved the problems of establishing a model of the dispersion data of the geological structure of the intrinsic small samples and revealed the changes in the characters, extent, scope and tendency of the inner and outer ore-controlling structure indicators and the regularity of the transfer evolution in multi-dimensional time-space for the mineralization marks and the relative quality of the orebodies. This study presents a new knowledge and way for the study and prediction of concealed ore deposits and prospects.
