本文试用两种多元统计法,对A区52个总γ强度较围岩明显偏高及有较大分布面积的、并具代表性的高场进行了分类和铀成矿远景对比。一、A区地质概况该区处在环太平洋构造区内一中生代构造带的南东部。由于它受到一东西耐构造带与某北东至北北东向构造带的复合部位控制,所以区内构造活动频繁而强烈,为本区成岩、成矿创造了重要的构造前提。
In this paper, two kinds of multivariate statistical methods are used to compare the classification and uranium metallogenic prospects of 52 high-intensity areas in Area A which are obviously higher than the surrounding rock and have a relatively large distribution area. I. Geological Survey of Area A This area is located in the south-eastern part of a Mesozoic tectonic belt within the Pacific Rim. Due to the fact that it is controlled by a composite structure of a structural resistance belt and a North-East-North-East structural belt, tectonic activity in the area is frequent and intense, creating important structural prerequisites for diagenesis and mineralization in this area.
