摘要:
河南内乡—淅川地区具有一完整的边缘成矿体系。应用边缘成矿理论,通过野外对该区控矿要素的实际 调研和室内对比分析,提出了豫西南内乡—淅川地区边缘成矿体系的新认识。一级成矿边缘为华北板块与扬子 板块边缘对接处(山阳—西峡断裂带两侧),控制了两个跨省大型成矿带的形成;二级成矿边缘为区域深大断裂 边缘,控制区域成矿带形成;三级成矿带边缘为岩体边缘、次级断裂带边缘和地层交界面等,控制矿田、矿床的形 成;四级成矿边缘为岩体边缘不同岩相分界面、不同岩性层间面和构造形态、产状变化处。不同边缘交叉、叠合 地段是成矿最有利地段。研究表明,边缘成矿体系的形成与地质异常事件密切相关,板块活动、区域构造、火山、 岩浆侵入、沉积环境演化是边缘成矿体系形成的主导因素。根据边缘成矿规律进行了成矿预测,指出主要找矿 方向和有利找矿区段(靶区)。
Abstract:
There is a complete marginal ore-forming system from Neixiang to Xichuan in the Southwest of Henan Province. It’ s a mineralized concentration area for all kinds of metals, gold, silver, copper etc. The different mineral deposits have different condition in orefield, but all have marginal ore-forming characteristic. Through researching the ore-forming characteristic in the area, this paper gets the marginal ore-forming regularity. The regularity possesses the important guiding and applied significance. Applying marginal ore-forming theory, this paper carries practical investigation on the ore control factors in field, poses the new knowledge of marginal ore- forming system in the Neixiang to Xichuan area of the southwest of Henan Province. The first ore-forming margin is the interface where Huabei plate and Yangzi plate(two sides of Shanyang to Xixia faulted zone), which control the forming of two major mineralization belt; the second ore-forming margin is the largely region fault margin and the vice-structural unit margin,which control the forming of region mineralization belt; the third ore- forming margin is the rock mass margin,vice-faulted zone margin and stratigraphic plane, which control the forming of orefield and mineral deposit; the forth ore-forming margin is the different facies plane,the different facies interlayer plane and the area of changing with structural form and occurrence. The different marginal intersection and superimposed section are the beneficial for ore forming. The marginal ore-forming system is close related to geological anomaly event. Plate motion, areal structure, volcano, magma, intrusion, sedimentary environment evolution are dominant factors that the forming of marginal ore-forming system, and with the marginal ore-forming regularity. This offers the ore-forming prediction, then indicate the major direction for ore hunting and the beneficial region for ore-forming(target area).
