【摘要】 采用电子探针、等离子质谱、等离子光谱等测试方法对河南栾川透闪石玉进行了研究,并结合国内其他产地的透闪石玉进行了分析比较。结果表明,河南透闪石玉的主要矿物组成为透闪石,其化学组成特征与和田玉相似。初步推断其矿床成因为岩浆热液交代成因。更多还原

【Abstract】 Using such means as electron microprobe analysis,ICP-MS and ICP-AES,the authors studied the tremolite jade from Luanchuan tremolite jade deposit in the western part of Henan Province.The results show that the samples are almost exclusively composed of tremolite,and are quite similar to Hetian jade in chemical composition.It is held that this tremolite jade deposit is probably a magmatic hydrothermal replacement deposit.更多还原
