摘要
本文对珠江干流和珠江口海区悬浮体,首次应用微孔滤膜过滤,并作了初步研究。该区悬浮体主要为陆源粘土矿物伊利石、高岭石、绿泥石和碎屑矿物石英、钾长石、斜长石等无机成分;有机成分较少。它们的含量变化和分布状况,受大陆径流、也受潮汐和地貌等因素影响。它们大部分沉积在河口三角洲前缘,只有少量向远处扩散。
In this paper, the mineral composition of suspended matter collected through minipore filter has been preliminarily studied in the Zhujiang River and its estuary for the first time. In this area the suspended matter is basically terrigenous and is composed of clay minerals,such as illite,kaolinite,chlorite; and detritus minerals,such as quartz,potassium feldspar,oblique feldspar;while organic matter is relatively minor. Their content and distribution are affected by runoff, tide and relief. Most of them are deposited in the frontal edge of the estuary and its delta, only a small amount is being diffused far away.
