摘要
作者用实体镜和偏光显微镜对浙江沿岸重矿物进行了鉴定和研究。已鉴定出重矿物约40种,其中角闪石、绿帘石、磁铁矿、钛铁矿含量较高,白云母、黑云母、绿泥石、黄铁矿以及辉石、锆石、石榴石、(?)石、磷灰石、十字石等次之。根据重矿物含量变化,我们将浙江沿岸碎屑矿物大致划为8个组合类型,并认为控制矿物组合的主要因素是母岩性质和水动力条件。
The heavy minerals in the Zhejiang coastal region have been studied by using stereoscopic and polarizing microscopes and about 40 minerals have been identified in which higher contents are hornblende, epidote, magnetite and ilmenite, others are muscovite, biotite, chlorite, pyrite, augite, zircon, garnet, apatite, sphene and staurotide. The minerals can be divided into eight assemblages based on the differences of heavy minerals. Nature of mother rock and hydrodynamic conditions are considered to be the main factors controlling mineral assemblages.
