一、前言鋰鈹石Li_2BeSiO_4为一罕見高鋰、鈹的硅酸盐矿物,見于某地矽卡岩体接触带的鋰云母脉中。鋰鈹石于1959年采选矿试料时在薄片中发現,当时由于样品有限,未能对該矿物进行詳細研究工作,仅对該矿物作了初步光性測定及光譜半定量分析,发現其与任何已知矿物均不相同,1963年春,笔者又赴該区采集标本,继續进行工作,目前除部分X-光工作尚在进行外,其它工作已大部分进行完毕,据已取得之成果証实鋰鈹石为一前所未見的新矿物。
I. Introduction Lithium beryllium Li_2BeSiO_4 is a rare high-grade lithium and beryllium silicate mineral found in the leached mica vein at the contact zone of some skarn bodies. Lithium beryllium was found in flakes when ore samples were collected in 1959. At that time, due to the limited sample, the mineral was not studied in detail and only the preliminary photometric determination and spectral semi-quantitative analysis of the mineral were made and found that It is different from any known mineral. In the spring of 1963, the author went to the area again to collect specimens and continue the work. Currently, most of the other work has been completed except for some X-ray work. According to what has been obtained The results confirmed that lithium beryllium stone is an unprecedented new mineral.
