应用矿物资料统计分析方法研究海洋沉积物的来源、矿物组合区和沉积环境特点在国内外已有一些报导。在石臼所深水港选址期间,我们曾对鲁南近岸带的重矿物来源、扩散型式和分布特征作过初步研究。本文对该区的81个样品(站位)中的24种重矿物资料进行了Q型统计分析。此分析以Q因子为基础,兼用聚类法和多端元相关法。文中并根据统计分析结果给出的分区图示,对重矿物来源和海岸动态作了分析研究。
The application of statistical methods of mineral statistics to study the origin of marine sediments, mineral assemblages and sedimentary environment has been reported at home and abroad. During the siting of the Shijiu Su Depot, we conducted a preliminary study of the source, distribution and distribution characteristics of heavy minerals in the Lunan nearshore. In this paper, Q-type statistical analysis of 24 heavy minerals in 81 samples (stations) in this area was carried out. This analysis is based on Q-factor, using both clustering and multi-end correlation methods. Based on the zonation diagrams given in the statistical analysis results, the source and coast dynamics of heavy minerals are analyzed.
