摘　　要：根据加里福尼亚州的"加州玉"和缅甸"困就"的物理性质、矿物组成、化学成分及红外光谱特征,确定"困就"的主要矿物成分是透闪石,"加州玉"的主要矿物成分为阳起石,两者的宝石名称是软玉。此两玉石较新疆和田、江苏溧阳、辽宁岫岩、俄罗斯贝加尔湖软玉具有较高的Fe、Cr、Ni含量,其矿床类型均为透闪石化或阳起石化超基性岩型。紫外可见吸收光谱特征及化学成分表明:Cr是它们的一个重要致色元素。Based on physical properties, mineral composition, chemical components and infrared spectra, the main mineral components of 'Kunjiu Jade' and 'California Jade' are proved to be tremolite and actinolite respectively. Both Jades belong to nephrite in gem classification and ultrabasic rock in mineral deposit classification. There are more Fe, Cr and Ni in 'California Jade' and 'Kunjiu Jade' than those in the nephrite from Hetian (Xinjiang), Liyang (Jiangsu), Xiuyan (Liaoning) and Baikal Lake (Russia).And the UV/VIS spectra and chemical components from both Jades indicate that Cr is an important coloring element.
