摘要
重点论述开展大比例尺找矿预测是实现科学找矿的重要途径,也是当前寻找隐伏矿、深部矿的有效方法之一。论述大比例尺找矿预测工作的特点和任务、基本准则、方法技术要求以及预测中GIS应用。大比例尺找矿预测是指在已知成矿区带或矿田内开展的1∶25000—1∶50000、1∶10000或更大比例尺找矿预测。以往找矿经验表明,开展大比例尺找矿预测是实现科学找矿的重要途径,也是提高地质找矿效果的有效方法之一。因而它应贯穿勘查工作的始终,尤其是在普查找矿的前阶段更需要加强这项工作。在地质工作程度较高,且以寻找隐伏矿、深部矿为主要任务的地区,更需进行大比例尺找矿预测,以提高地质找矿效果,为我国矿业发展提供足够的后备资源。因此,在已具备条件的地区,应有计划、有步骤的开展大比例尺找矿预测工作,力争用较快的速度发现又多又好的矿产地。
This paper focused on expounding that big-scale ore-prospecting prognosis is an important way of achieving scientific exploration of ores and is currently one of effective methods for seeking hidden and deep-seated ore deposit. It also described the characteristics, task, basic rules, methodological and technical requirements and application of GIS in prognosis. Big-scale ore-prospecting prognosis refers to carrying out 1：25000 - 1：50000,1：10000 or bigger-scale prognosis in already known ore-forming zone or ore field. Past experiences in ore prospecting has proved the importance of the method, so it should be valued in the whole process of exploration, especially at the initial stage of reconnaissance. It is more necessary to conduct big-scale ore-prospecting prognosis in regions with high-degree geological work and with seeking hidden and deep-seated ore deposit as the major task, thus improving the work effect.
