前言分析研究沉积物中重矿物含量、矿物组成、主要重矿物及标志性矿物的分布规律、相近物理化学性质的矿物比率变化、矿物组合分区特征、对于查明某区泥砂来源、运移方向及扩散趋势是一种有效的手段.重矿物分析在胶州湾洄淤调查中得到了应用。我们共分析海区表层沉积物样品70个(见附图1),岸滩及河流样品9个。海区样品分析的取样原则基本上是均匀分布,河口区略有加密。仅对粒径为0.063—0.125mm 的
Preface Analyzes the distribution of heavy minerals, mineral components, major heavy minerals and major minerals in sediments, mineral ratios of similar physical and chemical properties, and zoning characteristics of mineral assemblages. It is of great significance in identifying the source of sediment, the direction of migration and The trend of diffusion is an effective measure.Heavy mineral analysis has been applied in the investigation of the siltation in Jiaozhou Bay. We analyzed a total of 70 surface sediment samples from sea areas (see Figure 1), 9 from shore beaches and river samples. The principle of sampling for sea area sample analysis is basically uniform and the estuary area is slightly encrypted. Only for the particle size 0.063-0.125mm
