Apophyllite

鱼眼石是一种含水钾钙硅酸盐矿物。四方晶系,晶体常见尖锥状、等轴状或板状,集合体呈叶片状。无色和浅湖绿色为主,其他还有黄色、紫色、粉红色等,通常都为浅色调。透明至半透明,玻璃至珍珠光泽。光性特征:正交镜下常有异常干涉色,对蓝光而言是一轴负晶,对红光是一轴正晶。鱼眼石常见气液内含物,颇具特征,常伴有裂隙。

·鱼眼石晶体常呈尖锥状

·鱼眼石的生长纹

鱼眼石是低温热液矿物,产于基性火山岩的气孔中。产地主要有印度、墨西哥、美国、加拿大、巴西、芬兰、德国和中国等。巴西曾发现长20厘米的晶体。鱼眼石性脆,硬度不高,宝石一般用作收藏,天然晶体可作为精美的观赏石。

·鱼眼石双锥状晶体

Apophyllite is a widespread mineral belonging to the phyllosilicates group. It frequently occurs with zeolite in basalt and less commonly in granite cavities in massive, tabular, or prismatic form. Its clear, aqua,or green crystals have high water content and will conduct electricity but will also flake when heated, hence its name meaning “get” and“leaf” in Greek.
